I am using particle js as a background image.Now
<div id="particles-js"></div>
<div class="text">
<h1>Particles Background</h1>
</div>
I have to set position attribute of .text as absolute. Otherwise the section remains hidden. I don't seem to understand why others become hidden. I can't use absolute as it will break my code. Below is the css. Only if I set .text as position:absolute it will display
#particles-js {
position: relative;
width: 100%;
height: 100%;
background: grey;
}
.text {
position: relative;
top: 50%;
right: 50%;
}
<div id="particles-js"></div>
<div class="text">
<h1>Particles Background</h1>
</div>
You are facing this issue possibly because of heighr z-index value for #particle-js
You can do it by either making position: absolute; for #particle-js and/or increasing the z-index for .text
To understand more about positions please check this link
You are using divs which by default have layout but with no contents have no size. You also position the right of one element so the text is off screen. You can then fix that by right align of the text in the div. Here I put two examples to help understand the differences, one with no content as you have and one with a right aligned text.
I put some borders on just so you have a visual of the elements.
#mycontainer{border:solid lime 1px;}
#particles-js {
position: relative;
width: 100%;
height: 100%;
background: grey;
border: solid 1px blue;
}
.text {
position: relative;
top: 50%;
right: 50%;
border: solid 1px red;
}
<div id="mycontainer">
<div id="particles-js">cheese </div>
<div class="text">
<h1>Particles Background</h1>
</div>
</div>
Second example
#mycontainer {
border: solid lime 1px;
width: 100%;
height: 100%;
}
#particles-js {
position: relative;
width: 100%;
height: 100%;
background: grey;
border: solid 1px blue;
}
.text {
position: relative;
top: 50%;
right: 50%;
border: solid 1px red;
text-align:right;
}
<div id="mycontainer">
<div id="particles-js">
</div>
<div class="text">
<h1>Particles Background</h1>
</div>
</div>

I have a div, which has an image inside another div. I would like to place the inner div over the second div. So the arrow in the image below should go over the red. Is this possible?
.puscicaAnimacija {
bottom: -2%;
height: 5%;
margin-bottom: -10px;
z-index: 2;
position: absolute;
}
<div class="first">
<div style="display: flex; justify-content: center;">
<img src="https://via.placeholder.com/100" class="puscicaAnimacija" />
</div>
</div>
<div class="second">
</div>
You should put position:relative on the second div that refers to the .puscicaAnimacija class, then using the property z-index on the second element with an higher value than in the first.
.puscicaAnimacija{
position: relative;
}
.second{
position: absolute;
z-index: 3;
}
Note:
I've converted a few of your classNames to use named classes as well as added some additional CSS for demonstration purposes
Perhaps try something like this:
.first {
background: navy;
width: 300px;
height: 100px;
position: relative;
}
.ontop {
background: whitesmoke;
width: 300px;
height: 50px;
position: absolute;
bottom: 0;
}
.second {
background: red;
width: 300px;
height: 50px;
}
.puscicaAnimacija {
bottom: -40%;
left: 10%;
height: 48px;
position: absolute;
}
<div class="first">
<div class="ontop">
<img src="https://cdn-icons-png.flaticon.com/512/159/159119.png" class="puscicaAnimacija" />
</div>
</div>
<div class="second">
</div>
In order to use z-index the parent element must be positioned. Use position:relative on the div you want to go under.
I'm trying to create a design using multiple divs using CSS.
I'm already written code for it but don't know what is the problem with my code as my left and right side div not aligning at vertically center and all the divs are not overlapped with main yellow centered div which is I'm unable to achieve.
Note: I tried this with z-index but did not get what I want.
Output I'm getting:

Please somebody help me with the Source Code I tried almost all the related answer.
You can use Flexbox or Positioning.
Using Positioning makes it more flexible to add content to the holder element.
While Flexbox is more flexible when it's about adding and aligning boxes.
# Positioning
Description:
Create 4 elements to be the boxes.
Each .box has it's direction.
Example: <div class="box top"></div>.
Wrap all of them in div.boxes. This way you can separate the .boxes from the content (if there) in the holder,
<div class="boxes">
<div class="box top"></div>
<div class="box right"></div>
<div class="box left"></div>
<div class="box bottom"></div>
</div>
Style the the position of .wrapper so all the positioned absolute elements stays in the .wrapper.
.wrapper {position: relative;}
Finally, set the position of each box:
Example:
.box.top {
top: 0;
left: 50%;
transform: translateX(-50%);
margin-top: -40px;
}
Notes:
Don't use:
left property on .box.right.
top property on .box.bottom.
It won't set the negative margin which pushes them to edges.
In case content added to the holder (.wrapper), wrap the content in div.content and add inner space using padding. The value of padding in the code example is 40px, which it's related to the .boxes dimenstions.
The space (padding) is added to prevent overflow between content and .boxeses. And we can go further with styling the .boxes with overflow and z-index property.
For more about using negative maring and the boxes dimenstions:
Check for Notes in Flexbox
The Code:
* {
margin: 0;
padding: 0;
box-sizing: border-box;
}
.wrapper {
position: relative;
width: 600px;
height: 600px;
border: 1px solid;
margin: 50px auto;
}
.box {
position: absolute;
border: 1px solid;
background-color: red;
}
.box.top, .box.bottom {
width: 200px;
height: 80px;
}
.box.left, .box.right {
width: 80px;
height: 200px;
}
.box.top {
top: 0;
left: 50%;
transform: translateX(-50%);
margin-top: -40px;
}
.box.bottom {
bottom: 0;
left: 50%;
transform: translateX(-50%);
margin-bottom: -40px;
}
.box.left {
top: 50%;
left: 0;
transform: translateY(-50%);
margin-left: -40px;
}
.box.right {
right: 0;
top: 50%;
transform: translateY(-50%);
margin-right: -40px;
}
.content {
padding: 40px; /* check notes */
}
<div class="wrapper">
<div class="boxes">
<div class="box top"></div>
<div class="box right"></div>
<div class="box left"></div>
<div class="box bottom"></div>
</div>
<div class="content">
<h1>Hello World!</h1>
</div>
</div>
# Flexbox
Description:
Create 3 elements to hold the .boxes.
top: holding top box
center: holding left and right boxes
bottom: holding bottom box
In other words:
Each .box is nested (a child) in a div that has the class of the direction.
Example: <div class="top">BOX</div>.
Left and right are nested in center.
HTML:
<!-- top box -->
<div class="top">
<div class="box"></div>
</div>
<!-- left, right boxes -->
<div class="center">
<div class="left">
<div class="box"></div>
</div>
<div class="right">
<div class="box"></div>
</div>
</div>
<!-- bottom box -->
<div class="bottom">
<div class="box"></div>
</div>
Wrap all of them in a div.wrapper:
<div class="wrapper">
<!-- top box -->
<div class="top"></div>
<!-- left, right boxes -->
<div class="center"></div>
<!-- bottom box -->
<div class="bottom"></div>
</div>
The lines below will style the 3 elements and set them to their positions, .top will be centered (left right) and on top, .center will be centered from all the directions, .bottom is centered (left right) and at the bottom, by displaying the .wrapper children horizontally (flex-direction: column;) and centered (align-items: center;) with (space-between) them, using flex.
Check: A Complete Guide to Flexbox
.wrapper {
display: flex;
flex-direction: column;
align-items: center;
justify-content: space-between;
}
Then we do something similar with the .center element, by displaying both of left and right next to each other, centered and space-between them.
(No flex-direction property in the declaration, since the default is in a row (vertically))
.wrapper .center {
width: 100%; /* Don't delete, check notes */
display: flex;
justify-content: space-between;
align-items: center;
}
And finally, with negative margin we move the boxes to the edges.
.top .box {
margin-top: -40px;
}
.bottom .box {
margin-bottom: -40px;
}
.center .left .box {
margin-left: -40px;
}
.center .right .box {
margin-right: -40px;
}
Notes:
The left and right boxes are (width: 80px), each, which means the margin should be -40px (80 / 2 = 40) to set on center.
left: margin-left: -40px
right: margin-right: -40px
Same for top and bottom, since the dimensions are flipped.
top: margin-top: -40px
bottom: margin-bottom: -40px
This way, all the boxes are gonna be centered at the edges.
By default, when displaying with flexbox, the parent(.center) will take the width of it's content/children (fitted)! which means, width: 40px * 2, since we have 2 boxes in there. Now to make sure that the space-between value works, we should "stretch" the .center element (parent) by styling it's width to 100% which allows to the boxes to have as much as space-between, then every box is gonna be on it's position.
.wrapper .center {
width: 100%; /* Don't delete, check notes */
}
The Code:
* {
margin: 0;
padding: 0;
box-sizing: border-box;
}
.wrapper {
border: 1px solid;
max-width: 600px;
min-height: 600px;
margin: 60px auto;
display: flex;
flex-direction: column;
align-items: center;
justify-content: space-between;
}
.box {
border: 1px solid;
background-color: red;
}
.wrapper .top .box,
.wrapper .bottom .box {
width: 200px;
height: 80px;
}
.wrapper .center .box {
width: 80px;
height: 200px;
}
.top .box {
margin-top: -40px;
}
.bottom .box {
margin-bottom:-40px;
}
.wrapper .center {
width: 100%; /* Don't delete, check notes */
display: flex;
justify-content: space-between;
align-items: center;
}
.center .left .box {
margin-left: -40px;
}
.center .right .box {
margin-right: -40px;
}
<div class="wrapper">
<div class="top">
<div class="box"></div>
</div>
<div class="center">
<div class="left">
<div class="box"></div>
</div>
<div class="right">
<div class="box"></div>
</div>
</div>
<div class="bottom">
<div class="box"></div>
</div>
</div>
EDIT:
As #anatolhiman mentioned in the comments:
but negative margins will create a problem by having the elements
overflowing right and left (especially on narrow screens).
A simple solution:
(same works for both examples)
wrap the HTML that we added before in another div, .container for example, and add spacing with CSS, either padding or margin works, depends on your situation.
So the question is...
Is it a space within the .container? --> padding.
Or outside of it? --> margin.
Give the .container a background-color, resize the window, and check both margin and padding to see the differences.
HTML - Update:
<div class="container">
<div class="wrapper">
</div>
</div>
CSS - Add:
/* outside space */
.container {margin: 50px;}
/* Or */
/* inside space */
.container {padding: 50px;}
You may have to edit the margin property in .wrapper for top bottom.
Extra space added (50px) to include spaces for the .boxes as well.
Remember: .wrapper{max-width: VALUE} is taking a place in this functionality, since it's max-width is X but it could be smaller. So if the property is width: and not max-width then it'll behave differently, and won't work as expected (fully responsive), unless we use #media query or JavaScript.
Maybe something like following snippet, with absolute positioning:
.maind {
margin: 0px auto;
width: 90%;
padding: 10px;
height: 900px;
background-color: rgb(9, 252, 9);
position: relative;
}
.fdiv {
margin: auto;
width: 25%;
padding: 10px;
height: 100px;
background-color: rgb(10, 233, 222);
margin-top: 30px;
border: 2px solid red;
position: absolute;
top: 0;
left: 35%;
z-index: 22;
}
.sdiv {
width: 80%;
position: absolute;
top: 10%;
left: 10%;
height: 600px;
background-color: #ffff00ec;
z-index: 12;
margin: 0 auto;
}
.tdiv {
margin: auto;
width: 25%;
padding: 10px;
height: 100px;
background-color: rgb(10, 233, 222);
border: 2px solid red;
position: absolute;
bottom: 20%;
left: 35%;
z-index: 22;
}
p {
text-align: center;
}
.wrap {
display: flex;
flex-direction: row;
}
.wr1 {
width: 25%;
height: 100px;
background-color: rgb(10, 233, 222);
border: 2px solid red;
position: absolute;
top: 35%;
left: 0;
z-index: 22;
}
.wr2 {
width: 25%;
height: 100px;
background-color: rgb(10, 233, 222);
border: 2px solid red;
position: absolute;
top: 35%;
right: 0;
z-index: 22;
}
<div class="maind">
<div class="fdiv">
<p>Top...</p>
</div>
<div class="wrap">
<div class="wr1">

I have a position absolute element which has a min-width. What I want to do is to align the absolute element's end to the relative element's end.
The relative element DOES NOT have a fixed width. The width can be vary depending on the content inside.
The use case here is, I'm building a custom dropdown. The relative element is the label which has the selected text and the position absolute element is the dropdown.
<div class="container">
<div class="text">Text from list</div>
<ul class="list">...</ul>
</div>
The image above has the look I'm expecting. What should I do to get this alignment? Can it be done with pure CSS?
.relative-div {
position:relative;
min-height: 50px;
background:#BB9A9B;
}
.abs-div {
position: absolute;
right: 0;
top: calc(100% + 10px);
min-width: 100px;
min-height: 50px;
background: red;
}
<div class="container">
<div class="relative-div">
relative-div
<div class="abs-div"></div>
</div>
</div>
.element {
padding: 0.75rem 1rem;
border: 1px solid navy;
background-color: dodgerblue;
color: white;
margin: 10px 0px;
}
.parent-class {
position: absolute;
right: 0px;
}
.relative-element {
position: relative;
}
.absolute-element {
position: absolute;
min-width: 200px;
right: 0px;
}
<div class="parent-class">
<div class="element relative-element">Relative Element</div>
<div class="element absolute-element">Absolute Element</div>
</div>
i would recommend to use flex-box. here is a cheat-sheet https://css-tricks.com/snippets/css/a-guide-to-flexbox/
Are there any ways that we can set a tag inside a div perfectly center no matter what is the width and height of that div? In other way, I want to set an image position inside a div tag like a center background. For example:
.image-wrap {
width: 50vw;
height: 720px;
background: url('some-images.jpg') no-repeat center center / auto 100%;
}
I want to set an image inside a div like a background above with auto width and 100% height so that all the important content in an image will be in the center of the div.
<div class="image-wrap">
<img src="some-images.jpg" alt="some image here"/>
</div>
Thank you very much!
You can center it easily using flex property. Demo here
.image-wrap {
height: 400px;
display: flex;
align-items: center;
justify-content: center;
border: dotted 1px #CCC;
}
<div class="image-wrap">
<img src="http://lorempixel.com/400/200" alt="some image here"/>
</div>
You could use transform: translate
.image-wrap {
position: relative;
height: 400px;
text-align: center;
border: 1px dashed gray;
}
.image-wrap img {
position: relative;
top: 50%;
transform: translateY(-50%);
}
<div class="image-wrap">
<img src="http://placehold.it/200" alt="some image here"/>
</div>
Now, if you want it to behave as background-size: auto 100% does, do like this
.image-wrap {
position: relative;
height: 200px;
border: 1px dashed gray;
overflow: hidden;
}
.image-wrap img {
position: relative;
height: 100%;
left: 50%;
transform: translateX(-50%);
}
<div class="image-wrap">
<img src="http://placehold.it/600x100" alt="some image here"/>
</div>
<div class="image-wrap">
<img src="http://placehold.it/200x400" alt="some image here"/>
</div>
And here is a version behaving as background-size: cover does
.image-wrap {
position: relative;
height: 200px;
overflow: hidden;
border: 1px dashed gray;
margin-bottom: 10px;
}
.image-wrap img {
position: relative;
min-height: 100%;
min-width: 100%;
top: 50%;
left: 50%;
transform: translate(-50%,-50%);
}
<div class="image-wrap">
<img src="http://placehold.it/600x100" alt="some image here"/>
</div>
<div class="image-wrap">
<img src="http://placehold.it/200x400" alt="some image here"/>
</div>
And this version behaving as background-size: contain does
.image-wrap {
position: relative;
height: 200px;
overflow: hidden;
border: 1px dashed gray;
margin-bottom: 10px;
}
.image-wrap img {
position: relative;
max-height: 100%;
max-width: 100%;
top: 50%;
left: 50%;
transform: translate(-50%,-50%);
}
<div class="image-wrap">
<img src="http://placehold.it/600x100" alt="some image here"/>
</div>
<div class="image-wrap">
<img src="http://placehold.it/200x400" alt="some image here"/>
</div>
You could do it like so:
.image-wrap {
width: 50vw;
height: 720px;
background: url('some-images.jpg') no-repeat center center / auto 100%;
position: relative;
}
img
{
position: absolute;
top: 50%;
left: 50%;
margin-left: -200px; /* (EXAMPLE) - value should be half of the image width */
margin-top: -100px; /* (EXAMPLE) - value should be half of the image height */
}
<div class="image-wrap">
<img src="some-images.jpg" alt="some image here"/>
</div>
.parent-div {
width: 50vw;
height: 720px;
position: relative;
z-index: 1;
}
.image-wrap {
background-position: 50% 50%;
background-size: cover;
position: absolute;
top: 0;
right: 0;
bottom: 0;
left: 0;
z-index: -1;
}
you can use like this
<div class="parent-div">
<div class="image-wrap" style="background-image: url('http://weknowyourdreams.com/images/nature/nature-02.jpg')"></div>
</div>
This is where FlexBox properties become very useful. You can set align-items: center; on a container to (by default) vertically center any child elements. Here's an example: https://jsfiddle.net/ks62qtns/
The advantage of this is that you don't need to know the dimensions of any of the elements involved in the layout - which is very useful for responsive designs and/or dynamic content.
Flex properties are reasonably well supported in modern browsers. You might need fallbacks to support older versions of IE (if you need to)
HTML:
<div class="container">
<div class="content">
<h1>
Content. Any Content.
</h1>
<p>
I might have anything in me!
</p>
</div>
</div>
CSS:
.container {
display: flex;
align-items: center;
justify-content: center;
background: #EEE;
/* This is just to make a big container. You can set the dimensions however you like.*/
position: absolute;
top: 0;
right: 0;
bottom: 0;
left: 0;
}
.content {
background: #89D485;
padding: 2rem;
text-align: center;
}
This is the most over thought out problem that most developers run into.
If the object is inside another object you are able to just use margin: 0 auto; inside the CSS. This will make the left and right ways to line up correct. This also then works for all media queries from small screen to large screens.
You can use jquery to calculate the width of the div and image.
$(img).css({
position: "absolute",
left: ($(img).parent().width() - $(img).width()) / 2
});
This would mean:
((width of div)-(width of image))/2
This would center image perfectly.
just do it like this.set the container's property "text-align:center",make it is the inline-block element and 100% height，then can get what you want.
.image-wrap{
width: 50vm;
height: 720px;
text-align: center;
}
.image-wrap img{
display: inline-block;
height: 100vm;
}
Let's say I have four images inside a div. they all have a width of 5.5%
[_o__o__o__o_]
I want to use javascript to change the target that is moused over (hovered on), and have it look like this:
[_o__O__o__o_]
so I made the width of the target increase
however it also pushes the other elements to the side instead of staying where they are so it's more like:
[_o___O___o__o_]
I don't know how to make the other elements stay exactly where they are instead of being pushed.
The issue is that YES I am successfully able to alter the width.
BUT changing the width of one element pushes the surrounding elements to the respective right and left.
jsbin: https://jsbin.com/zujutamazo/edit?html,css,js,output
You can use flexbox for this one:
.wrapper {
display: flex;

As I was explaining, you need to set a higher z-index to "be above" the non-hovered boxes. And set negative left-right margins, equivalent to the additional width from hovering to prevent everything from moving around.
Below is a working example, with percentages.
body {
width: 300px;
height: 100px;
}
.myClass {
width: 20%;
height: 50%;
position: relative;
z-index: 1;
float: left;
}
.myClass:hover {
width: 30%;
height: 70%;
z-index: 10;
margin: 0 -5%;
}
body .myClass:nth-child(1) {
background-color: red;
}
body .myClass:nth-child(2) {
background-color: green;
}
body .myClass:nth-child(3) {
background-color: blue;
}
body .myClass:nth-child(4) {
background-color: yellow;
}
