Can someone please explain to me why i can't get the "Ken Burns" effect to show up properly when increasing the size of my images?
I pretty much tried hacking away at this with different images and different CSS settings but I really can't get them stacked and not floating outside the box. It's not interference with my CSS, as I tried it standalone as well.
I would like to have a banner with say a max of 1200x600 that fits the width of the screen. Please provide complete CSS.

Starting with this fiddle we see a basic animation of a box flying from its start position to its finish position. This is the known good code. (I tried it as a stackoverflow snippet, but it didn't work here for some reason.)
HTML
<div id="start">Start</div>
<div id="finish">Finish</div>
<div id="fly">Fly</div>
CSS
#start{
position:absolute;
background:red;
height:100px;
width:100px;
line-height:100px;
text-align:center;
left:0px;
}
#finish{
position:absolute;
background:blue;
height:100px;
width:100px;
line-height:100px;
text-align:center;
left:200px;
}
#fly{
position:absolute;
background:yellow;
height:100px;
width:100px;
line-height:100px;
text-align:center;
left:0px;
transition:1000ms;
}
#fly.finish{
left:200px
}
JavaScript
document.getElementById("fly").className = "finish";
-
Unlike the fiddle above this fiddle below however does not work. Rather than transitioning gently from the start location to the finish, it starts at the finish. This is because it should transition from a "left" property to a "right" property.
HTML
<div id="start">Start</div>
<div id="finish">Finish</div>
<div id="fly">Fly</div>
CSS
#start{
position:absolute;
background:red;
height:100px;
width:100px;
line-height:100px;
text-align:center;
left:0px;
}
#finish{
position:absolute;
background:blue;
height:100px;
width:100px;
line-height:100px;
text-align:center;
right:0px;
}
#fly{
position:absolute;
background:yellow;
height:100px;
width:100px;
line-height:100px;
text-align:center;
left:0px;
right:auto;
transition:1000ms;
}
#fly.finish{
right:0px;
left:auto;
}
Javascript
document.getElementById("fly").className = "finish";
Although I understand why this doesn't work, I need a box to fly to the right of the screen from just off the left edge of the screen. Most solutions to this issue either look strange on extremely wide screen devices, or have a slow response time on narrow mobile devices. I want an animation that's responsive to browser width, travelling more slowly across narrow screens and more quickly across wide screens.
What is the most elegant solution for this?
Ideally I'd like not to use any external libraries, but if I must, the page is already using jquery, so that would be the ideal one to use if that helps.
I'm not opposed to writing extremely long JavaScript functions, but shorter is always better.
As you know that the animation doesn't work cause can't animate two different attributes, in this case, changing left and right value in hope for the element to be animated.
My suggestion would be this:
#fly.finish {
left:calc(100% - 100px);
}
this is assuming that the box is always 100px width. Hope it helps!
Change your flying elements "left" property to (100% - elements width) as shown below.
#fly.finish{
left: calc(100% - 100px);
}
I want to make a gallery in HTML/CSS/jQuery. I have a bunch of thumbnails that all represent different images of varying sizes and orientations. When the thumbnail is clicked, I want the image to slide down from the top of the screen. The image should be as large as possible but still fitting in the window, taking into account margins and the like.
I have gotten all this to work properly in the past. However, now I want to add a caption below the image.
My solution was this. I have a div container that is fixed and is positioned with top:-96% and bottom:100% When a thumbnail is clicked, jQuery moves that to top:2% and bottom:2%
Previously I had a border that surrounded the image. Now I want to make that border actually part of a div instead, so that the border can go around the caption which should be below the image and centered, and said image.
Nothing I am doing is working, however. The image will not fit into the viewport, and will always be its max size no matter what I change the percent to.
I'm completely lost, I have no idea how to make this all work out. If you need code, I can give it to you, but as I said, it doesn't work. Thank you all in advance.
EDIT: Added code
HTML:
<div id=imgHoverCont>
<div id=imgBg>
<img id=imgHover src="" alt="">
<div id=commentHover></div>
</div>
</div>
CSS:
#imgHoverCont{
text-align:center;
position:fixed;
left:2%;
right:2%;
top:-96%;
bottom:100%;
}
#imgHover{
display:block;
height:100%;
width:auto;
}
#imgBg{
position: relative;
display: inline-block;
max-width:100%;
max-height:100%;
}
#commentHover{
position:absolute;
left:0;
bottom:0;
width:100%;
color:black;
background-color:white;
}
JS: Thumbnails are stored in an array of objects with their ID and their source.
for(let i in thumbnails){
$(thumbnails[i].id).on("click",function(livingHell){
return function(){
$("#imgHover").attr("src",thumbnails[livingHell].src)
$("#imgHoverCont").css("display","block");
$("#commentHover").html(thumbnails[livingHell].comment);
$("#imgHoverCont").animate({bottom:"2%",top:"2%"},1000);
}
}(i));
};
I've made some changes to your CSS
if I understood your question it works like expected, look here: https://jsfiddle.net/cratgjks/
#imgHoverCont{
text-align:center;
position:fixed;
left:2%;
right:2%;
top:-96%;
bottom:100%;
width:100%; /*new rule*/
}
#imgHover{
display:block;
height:100%;
width:100%;/*changed rule*/
}
#imgBg{
position: relative;
display: inline-block;
max-width:100%;/*changed rule*/
max-height:100%;
width:1500px
}
#commentHover{
position:absolute;
left:0;
bottom:0;
width:100%;
color:black;
background-color:white;
}
I am trying to do a simple thing. 3 div moving up and down on touch (for smartphone). On top of this 3 div, I'd like to have a canvas, to draw the edge of div. (In the example it is straight, but there will be some rotation and other beautiful canvas drawing...). I'd like to use canvas and not an img, to learn.
I use vh, vw to make it responsive. There is only 5 div.
I am not sure my solution to scroll up and down is a good idea. It represents when it is team 1 to play or team 2.
Here is my fiddle:
https://jsfiddle.net/Sulot/gzm6duzy/2/
#mycanvas{
pointer-events: none;
position:fixed;
top:0;
left:0;
width:100vw;
height:100%;
z-index:5;
border: 3px solid;
}
This css choice doesn't sound as a good idea.
Thanks,
Stéphane.
I have created div grid system with HTML and CSS using the float:left method.
It works fine, however whenever there is a variable height difference between two divs in the same row, the next div starts at the bottom most position just below the div that has the greatest height.
Here's the codepen:
http://codepen.io/anon/pen/GJZWoX
CSS:
.parent{
width:330px;
}
.red{
float:left;
width:150px;
height:150px;
margin-bottom:10px;
margin-left:10px;
background-color:red;
}
.blue{
float:left;
width:150px;
height:300px;
margin-bottom:10px;
margin-left:10px;
background-color:blue;
}
Is there a way to solve this error using just css? Any good answer would be appreciated.
This is what I'm looking for:
Thank you
Just CSS? With flexbox you could http://demosthenes.info/blog/844/Easy-Masonry-Layout-With-Flexbox
But I would opt for Javascript as a more robust (and slightly better browser support at the time of posting) approach.
via JQuery Masonry http://masonry.desandro.com/ (supported from IE9+)
I am trying to inject a banner div
<div id='banner'></div>
on top of an existing webpage in such a manner so that when a person scrolls the webpage the banner remains on top. Also the webpage should be pushed down by the banner so that every part of the page remains accessible.
Here is my CSS:
#banner {
position:fixed;
display:block;
top:0px;
background-color:#FFFFFF;
width:100%; height:250px;
border:2px solid;
}
Here is my jquery:
$("body").prepend("<div id='banner'></div>");
I tried using jquery to find all divs that were fixed and changing them to relative before executing the above line but still the banner does not work. The error is shown in the following picture https://drive.google.com/file/d/0B0sCu8aj8zu2akhtcEdtajJJZEU/edit?usp=sharing
Please Help.
And I am not looking for ad revenue here this is just a practice task.
Here is a jsFiddle I have created. The banner div is at the top of the page.
It stays at the top while scrolling.
The HTML:
<div class="page">
</div>
The css:
.oldBody
{
width:100%;
height: 3000px;
background-color: navy;
margin-top:250px;
}
#banner
{
position:fixed;
top:0px;
background-color:#FFFFFF;
width:100%;
height:250px;
border:2px solid;
z-index:10000;
}
The JS:
$("body").wrapAll("<div class='oldBody'></div>");
$("body").prepend("<div id='banner'></div>");
Please maintain z-index of banner div.Z-index should be grater then other div on that page.
#banner {
position:fixed;
display:block;
top:0px;
background-color:#FFFFFF;
width:100%; height:250px;
border:2px solid;
z-index : 99999
}
i'd just like to present a different way to create the element:
var $banner = $('<div/>', { 'id' : 'banner' });
$('body').prepend($banner);
this technique for creating elements with jquery comes in handy when you have several different element to create. as a note, you can also create the element like so:
var $banner = $('<div/>').attr('id', 'banner');
I think the best way is first keep your ad on top in relative position when a person scroll page your function check the page-scroll .scrollTop() and then add fixed position on banner ad container just like freeze header, if you need further help in this regard let me know, I will provide you code. thanks I hope this technique will help you
