I have more than one div that is positioned absolute and dynamically created by clicking on a button. Once clicked, they are placed in a container that is positioned relative, and I have a button on each div that when clicking on it, will delete the div, the problem is when deleting the div, it will affect the others positions.
function create() {
var $home = $('<div class="cabine"></div>');
$("#container").append($home);
}
.cabine { /*class that all div's share*/
position: absolute;
top:5%;
left:10%;
width:135px;
height:135px;
float:left;
background: red;
}
#container { /* Where the div's are placed*/
position: relative;
background-image: url(wall.jpg);
background-color: #FFFFFF;
border: 1px solid #000;
width: 100%;
height: 300px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button onclick="create()">Create Cabine</button>
<div id="container"></div>
In html you have #container instead of .container.

I have this image appended to a div JSFiddle
and my Div is inside a modal. I'v tried to display by default the bottom left quarter (like filling the div) and to allow the user to scroll horizontally and vertically to see the rest of the image but it seems that I have some blue areas and I cannot scroll till the end of the image.
imgUrl = "nerdist.com/wp-content/uploads/2018/02/year-or-the-tank-girl-header.jpg"
$('.img-wrapper').append($('<img id="theImg">').attr({
'src': 'https://' + imgUrl ,
'alt': 'test image'
})
)
.img-wrapper {
overflow: hidden;
height: 400px;
background-color: blue;
position: relative;
overflow-x:auto;
overflow-y:auto;
}
.img-wrapper > img {
display: inline-block;
height: 150%;
width: 150%;
position: relative;
top: -50%;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="myDiv" class="img-wrapper">
</div>
Is there a way to display, when the modal is open, just the bottom left quarter of the image and allow the user to scroll XY to see the rest of it?
I'm new in HTML programming so please be gentle :)
https://jsfiddle.net/2mLbhmuL/61/
CSS:
.img-wrapper {
overflow: auto; /* adds scrollbars */
height: 400px;
background-color: blue;
position: relative;
}
.img-wrapper > img {
height: 200%; /* probably looks neater if auto */
width: 200%; /* double width image to show only first quarter */
vertical-align: bottom; /* moves image to true text bottom */
}
JQuery
Add the following ScrollTop(9999) to the end of your existing JQ to jump the div to the bottom.
.scrollTop(99999)
It's a bit nasty hard-coding a large number but it saves getting a handle to the element (which would allow you to use its real height).
Note:
The vertical-align: bottom is needed for the image to display without showing your blue area underneath. The reason for that is an image is naturally positioned on the baseline of text, so the blue area you were seeing is the space for hanging letters.
The solution is quite simple:
Don't use display: inline-block; as it will place the image will be placed inline and with some margin down. Instead use display: block
The top: -50%; is also moving the picture 50% up leaving it's original position blank
You make this simple:
.img-wrapper {
height: 400px;
width:400px;
background-color: blue;
position: relative;
overflow-x:auto;
overflow-y:auto;
}
.img-wrapper > img {
position: relative;
}
<div id="myDiv" class="img-wrapper">
<img src="https://nerdist.com/wp-content/uploads/2018/02/year-or-the-tank-girl-header.jpg" id="theImg"/>
</div>
Try this: (Assumption - You will adjust for your image size and containing div size as required)
html
<div id="myDiv" class="img-wrapper">
<img src="http://nerdist.com/wp-content/uploads/2018/02/year-or-the-tank-girl-header.jpg">
</div>
JS:
var d = $('#myDiv');
d.scrollTop(d.prop("scrollHeight"));
CSS:
.img-wrapper {
height: 400px;
background-color: blue;
position: relative;
overflow-x:auto;
overflow-y:auto;
}
.img-wrapper > img {
display: inline-block;
position: relative;
border:1px solid red
}
The problem is I have 2 divs: one container a link and another a box shaped container. The link has a position:fixed; and it flies over the container div, so I tried to give the link a z-index with a negative value, turns out the
hover state does not work when applying z-index with a negative value for the anchor Unless I scroll the same amount of the height of the container div. So I scroll like 3 times and the hover state works again.
HTML
<div id="div-1">
<div class="container"></div>
</div>
<!-- other divs like 5 or 6 of 'em -->
<div id="div-2">
This is a link
</div>
CSS
#div-2 a{
width:13%;
height:auto;
padding:0.5em 2.3em;
display:block;
position:fixed;
font-weight:500;
font-size:1.09em;
text-align: center;
background-color: none;
text-decoration:none;
outline:none;
z-index:0;
}
#div-1{
width:100%;
height:290px;
overflow-y:auto;
overflow-x: hidden;
box-sizing: border-box;
display: block;
}
an important thing is:
The container is hidden by Jquery, unless I click a certain button.
$(document).ready(function(){
$(".container").hide();
$("#button-f").click(function(e){
$(".container").toggle();
var target = $(e.target);
if (!target.is("##button-f")) {
$(".container").toggle();
}
});
});
I have resorted to every possible (other ideas) I could think of. I tried to do the opposite meaning giving the container a z-index positive vales and leave the anchor, but that leaves the same problem
update
I will try to change the css property "z-index"but only when the the container button is toggled on
so the link will have z-index:-9; but only when the container is toggled to be viewed and when it is toggled back off the z-index will be removed or not applied.
I can't really figure how this will be written with jquery I tried this
$(document).ready(function(){
$(".container").hide();
$("#button-f").click(function(e){
$(".container").toggle();
$("#div-2 a").css("z-index", -9);
var target = $(e.target);
if (!target.is("##button-f")) {
$(".container").toggle();
}
});
});
this only result when I toggled the container on the z-index will be applied, but when i toggle it of it remains, how to remove the z-index or make it equal to z-inedx:99; when the container is toggled off?
Only any other answer for the problem is appreciated.
It's not clear what you want exactly, but the pics helped, although it appears that you want the link above the container, it looks as if you don't?
the whole purpose is to make the anchor in a lower index, so when the container is toggled on/ viewed, the link won't be setting on top of the container.
But you want the link to always react when hovered upon. So I assume that you can't figure out why it's not hovering when the container is open and you can still see the link, so logically you'd expect to at least be able to hover over the visible portion of the link.
It's not jQuery and it's not the .container. It's the .container's container A.K.A. #div-1. #div-1 width is always 100% and even if you didn't have that style, it would be 100% still because that's what blocks have if there isn't an explicit width assigned to it.
Solution: Give #div-1 a smaller width.
You have a fixed link yet no coords. You can't expect a fixed element to stand it's ground and behave like a fixed element if it doesn't know where to stand. Also if you have any positioned elements and you want interaction between other elements, make those elements positioned as well, div-1 is now position:relative and the z-index properties of the link and div-1 function correctly now.
Solution: Give #div-2 a top and left or right and bottom properties. Give #div-1 a position property so that the z-index functions properly.

Have you tried assigning a z-index to #div-2?
You'll need to assign it a position to be able to give it a z-index. Try this:
#div-2 a{
width:13%;
height:auto;
padding:0.5em 2.3em;
display:block;
position:fixed;
font-weight:500;
font-size:1.09em;
text-align: center;
background-color: none;
text-decoration:none;
outline:none;
z-index:2;
}
#div-1{
width:100%;
height:290px;
overflow-y:auto;
overflow-x: hidden;
box-sizing: border-box;
display: block;
position: relative;
z-index:1;
}
I don't know what actually in your code but the js you provide look at the if section you have (##button-f) so we find an error here and do we actually need this line ??like we also don't need the line 'container'.hide() in JS. Now you have to scroll for the 'a' certain height because yous set height for #div-1 which is not hidden. So that's amount of height you have to scroll.
So What I change on your code
1. cut the height of div-1 and place it to .container class. you dont provide the a:hover class so I add that to and remove some unnecessary css you have. If you have any other Question ask me in comment LIVE ON FIDDLE
$(document).ready(function() {
$("#button-f").click(function() {
$(".container").toggle();
});
});
button {
width: 13%;
height: auto;
}
#div-1{
width:100%;
overflow-y:auto;
overflow-x: hidden;

I have a function that when clicked takes the div container and centers it on screen, enlarged with fixed position and z-index of 2. I would like to dynamically create an element to sit z-index of 1 underneath the div with a black background, partially transparent, that hides the main content. How do I create and place this element into the page and delete it afterwards?
This demo has on overlay that's loaded on window onload event (#overlay).
There's a password input in #overlay (#pass is "off")
#overlay will use classList to change it's class to.off once the password is entered, thereby rendering #overlay non-existent (display: none).
var ov = document.getElementById('overlay');
var ps = document.getElementById('pass');
ps.addEventListener('change', function(e) {
if (pass.value === "off" && ov.classList.contains('on')) {
ov.classList.add('off');
ov.classList.remove('on');
} else {
alert('password is incorrect');
}
}, false);
function init() {
ov.classList.add('on');
}
window.onload = init;
#overlay {
position: fixed;
top: 0;
left: 0;
background: rgba(0, 0, 0, 0.6);
z-index: 1;
width: 100%;
height: 100%;
pointer-events: none;
}
.content {
border: 3px solid red;
width: 400px;
height: 200px;
margin: 50px auto;
padding: 10px;
}
p {
font: 600 16px/1.428'Arial' margin: 0 0 15px 10px;
}
#pass {
pointer-events: auto;
width: 100px;
line-height: 20px;
text-align: center;
margin: 25% auto 0;
display: block;
}
.off {
display: none;
}
.on {
display: block;
}
<div id="overlay" class="off">
<input id="pass" name="pass" type="password" placeholder="Enter Password">
</div>
<div class="content">
<p>xxxxxxxxxxxxxxxxxxxxxxxxxx</p>
<p>xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx</p>
<p>xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx</p>

I have a function that when clicked takes the div container and centers it on screen
Since you are doing this you have more control over it, All you have to so it is add this part of html along with this div of yours. (your div and this new div must be wrapped inside a parent div)
HTML
<div class="overlay-parent">
<div class="overlay"></div>
/* your div */
</div>
CSS
.overlay-parent{
width:100%;
height:100%;
overflow:hidden;
}
.overlay{
position:absolute;
top:0;
bottom:0;
width:100%;
background-color: black;
opacity:0.3;
}
This should be the structure when you are centering the div to center of the screen. And appending this structure to the body tag will get you the desired result
I'm trying to make the #header div clickable by wrapping a link element around it, but I cannot do it when it already has another image link inside the div. How would I fix this?
#header {
border: 1px solid red;
background-color: red;
}
img {
width: 50px;
height: 50px;
}
<a href = 'index.php'>
<div id = 'header'>
<a href = 'profile.php?username=$username'>
<img src = 'https://www.iscattered.com/uploads/1590Chocolate_chip_cookies.jpg'>
</a>
</div>
</a>
Now while the image link works just fine, the #wrapper div is not clickable.
#header {
border: 1px solid red;
background-color: red;
position: relative; /* establish nearest positioned ancestor for abs. positioning */
height: 50px;
}
#header a:first-child {
display: block;
height: 100%;
}
#header a:last-child {
position: absolute; /* image now independently clickable */
top: 0; /* position image anywhere you want inside #header */
left: 0;
}
img {
width: 50px;
height: 50px;
}
<div id='header'>
<a href='index.php'></a>
<a href='profile.php?username=$username'>
<img src='https://www.iscattered.com/uploads/1590Chocolate_chip_cookies.jpg'>
</a>
</div>
NOTES:
If you wrap a hyperlink inside another hyperlink, how is the browser supposed to know which link to execute?
Instead, make the #header element entirely clickable, and absolutely position the image.
Now the image can be clicked separately and positioned anywhere inside the #header element.
I know that a an element with position:fixed acts like its parent element with position:relative (Or no position specified) doesn't exist, and that's my concern. I've seen the very same question being asked here on StackOverflow, but not the very same problem.
I have a wrapper, an element with relative position, and an element with a fixed position inside the relative element. The element with fixed position should expand the element with relative position as you scroll the page, but what's happening is that when you scroll the page, the element with fixed position will go out of the main container, instead of expanding. How can I make the main element push the container element bellow, instead of getting an offset?
