How to re-create Facebook image modal? - javascript

I want to create something almost exactly like the Facebook image modal wherein the image is fixed while a user scrolls through the comments. I am messing with different ways to apply overflow: hidden to one div and overflow: scroll to the other. I even looked into applying it to their parent. Here is the code I've tried:
<div class="row container border border-primary">
<div class="image col border">
Image
</div>
<div class="text-section col border">
Comments
</div>
</div>
div.image {
height: 300px;
overflow: hidden;
}
div.text-section {
height: 1000px;
overflow: scroll;
}
div.container {
height: 300px;
}
Plunkr

I supposed a code like this. The blue (image) remains fixed on the left, while you can scroll the green section (comments) on the right
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<style>
#container { background: red; width: 400px; height: 150px; display: flex; }
#image { background: url("https://i1.adis.ws/i/canon/canon-pro-best-landscape-lenses-1-1140?w=200&aspect=4:3&qlt=70&sm=aspect&fmt=jpg&fmt.options=interlaced&fmt=jpg&fmt.options=interlaced&bg=rgb(255,255,255)"); width: 200px; height: 150px; }
#comments { background: #eee; width: 200px; overflow: scroll; padding: 0 10px 20px 10px; font-family: Verdana; color: black; }
</style>
</head>
<body>
<div id="container">
<div id="image"></div>
<div id="comments">
<h3 style="color: red;">Comments</h3>
<p>Nice!</p>
<p>Good!</p>
<p>Wonderful</p>
<p>Bah...</p>
<p>Strange</p>
<p>Nice again</p>
<p>Amazing</p>
<p>Beautiful</p>
<p>Great</p>
<p>I don’t like it</p>
<p>Yes, nice</p>
<p>Super</p>
<p>Normal</p>
<p>Ok...</p>
<p>Nice</p>
<p>Bah</p>
<p>Great</p>
<p>Nice</p>
<p>I like it</p>
<p>Normal</p>
</div>
</div>
</body>
</html>

I don't have facebook so cant look at the behaviour, but you could put position: sticky; on the image container, that will keep it in place. It also depends on your browser support, like ie11 does not support it, but there are more ways to do this. Let me know if you need a more cross browser solution.
.container {
max-height: 600px;
height: 100%;
overflow: auto;
position: relative;
}
div.image {
height: 300px;
background-color: deepskyblue;
position: sticky;
top: 0;
}
div.text-section {
height: 1000px;
background-color: aqua;
}
<div class="row container border border-primary">
<div class="image col border">
Image
</div>
<div class="text-section col border">
Comments
</div>

Fixed position when parent is relative

So not sure if this one is possible but from my understanding of the spec the parent of a position fixed element should be the viewport not a parent element with position relative.
That obviously all works when it comes to positioning but not with z-index.
If you take a look at this example,
.parent {
height: 1000px;
}
.el-one {
position: relative;
z-index: 2;
height: 100px;
width: 100%;
color: red;
}
.el-two {
position: relative;
z-index: 2;
background-color: black;
height: 500px;
width: 100%;
}
.im-fixed {
position: fixed;
top: 0;
left: 0;
}
<div class="parent">
<div class="el-one">
<div class="im-fixed">Hello</div>
</div>
<div class="el-two"></div>
</div>
https://codepen.io/anon/pen/mmvXaE
The fixed element goes behind the black section if you scroll down, what I need is a way to get the red element to the front without moving it out of el-one.
I have a project where some embed code needs to become fixed when you scroll past it, this is a better example of the actual code. The example above just highlights the issue in a simple way:
<div class="parent">
<div class="el-one">
<div id="my-wrapper">
<iframe class="im-fixed"></iframe>
</div>
</div>
<div class="el-two"></div>
</div>
,
I found this online talking about what I believe has caused the issue: https://developers.google.com/web/updates/2012/09/Stacking-Changes-Coming-to-position-fixed-elements but no luck finding a workaround.
All I can think of is using JS to move the element from where an editor puts the embed code and prepending it to the body when the user scrolls past the element.
Anyone else come across this or have any ideas?
You want something like this? Increase the z-index of .el-one higher than the one you want to overlap
.parent {
height: 1000px;
}
.el-one {
position: relative;
z-index: 99;
height: 100px;
width: 100%;
color: red;
}
.el-two {
position: relative;
z-index: 2;
background-color: black;
height: 500px;
width: 100%;
}
.im-fixed {
position: fixed;
top: 0;
left: 0;
}
<div class="parent">
<div class="el-one">
<div class="im-fixed">Hello</div>
</div>
<div class="el-two"></div>
</div>
Use the following:
.el-two {
position: relative;
z-index: -1;
background-color: black;
height: 500px;
width: 100%;
}
There are several ways to solve this issue. Increasing Z-Index, cleaning up the div and etc.
I think you are sort of trying sticky header functionality. There is a new value for position CSS attribute.
position: sticky
I have cleaned up the code and removed all Z-Index. Please check the attached code snippet.
Note: Supported only in Chrome, Firefox
Not supported in IE.
.parent {
background-color: green;
position: relative;
width: 100%;
height: 5000px;
}
.header {
position: sticky;
top: 0px;
left: 0px;
height: 50px;
background-color: yellow;
}
.el-one {
background-color: blue;
color: white;
height: 100px;
width: 100%;
}
.el-two {
background-color: orange;
height: 500px;
width: 100%;
}
<div class="parent">
<div class="header">I am a header</div>
<div class="container">
<div class="el-one">
I am el-one
</div>
<div class="el-two">
I am el-two
</div>

Grid with html/css as body background

I want to create a div that contains a grid generated with css, and that div appears behind other div, that contains the UI.
That is that one div in the body appears behind the other div that contains the user interface.
The div that is behind, must contain a grid drawing using CSS.
<head>
<style type="text/css">
#divcontainer {
width: 100%;
height: 100%;
position: absolute;
z-index: -999;
background-color: #bababa;
}
#divinnercontainer {
width: 10%;
height: 20%;
outline: 1px solid;
float: left;
}
</style>
</head>
<body>
<div class="divcontainer">
<div class="divinnercontainer"></div>
<div class="divinnercontainer"></div>
<div class="divinnercontainer"></div>
<div class="divinnercontainer"></div>
<div class="divinnercontainer"></div>
<div class="divinnercontainer"></div>
<div class="divinnercontainer"></div>
<div class="divinnercontainer"></div>
<div class="divinnercontainer"></div>
<div class="divinnercontainer"></div>
<div class="divinnercontainer"></div>
<div class="divinnercontainer"></div>
</div>
<div style="z-index:999">
<!-- UI -->
</div>
This is my code, but I don't see any grid, what I'm doing wrong?
Thanks in advance
The problem is because you use #divcontainer and #divinnercontainer instead of .divcontainer and .divinnercontainer.
you mixed up css classes with css ids.
You simply need to change
#divcontainer {
...
}
#divinnercontainer {
...
}
to
.divcontainer {
....
}
.divinnercontainer {
....
}
# is for id not for class
.divcontainer {
width: 100%;
height: 100%;
position: absolute;
z-index: -999;
background-color: #bababa;
}
.divinnercontainer {
width: 10%;
height: 20%;
outline: 1px solid;
float: left;
}
CodePen
in css is #divinnercontainer, but you call a divinnercontainer as a class in html
Your just need to fix the class name in your css :
#divcontainer to .divcontainer
#divinnercontainer to .divinnercontainer

How to make two sides equal height? One big div and some small divs

I have news section and on the left side of it there is one big div (main-article) on the right side some (4) small divs (sub articles). I need to make them equal dynamically (both sides should be visually equal):
I tried to make by jQuery and I partially achieved it, but with a really big bug. If the left side is too small, the right side articles will be too small and their text will overflow the containers:
Here is the HTML:
<div class="row">
<div class="col-md-6">
<article class="article-main_pg main-article article-main_pg--1">
<!-- image and text -->
</article>
</div>
</div>
<div class="row">
<div class="col-md-6">
<div class="row">
<!-- this four times -->
<div class="col-lg-6">
<article class="article-main_pg main-article article-main_pg--1">
<!-- image and text -->
</article>
</div>
<!-- this four times end -->
</div>
</div>
</div>
My jQuery attempts
// news section fix height
// get left news article height (without margin)
var leftArtHeight = $('.s10-news .main-article').outerHeight(false);
// reduce it by half and decrease by right side subarticles margin then add half of the margin (as we need to remember about 2 bottom subarticles margin)
// 25 is the margin (i know it, but ofcourse it can be set from DOM)
var heightForRightSubArt = (leftArtHeight / 2) - 25 + 13;
//finaly we set calculated height to the right subarticles and both sides are equal
$('.s10-news .sub-article').css("height" , heightForRightSubArt);
The result is ok BUT it's not responsive and it's a bug if the left side is too small.
try this, this may help to you.if this is not the case tell me.copy,paste , run and check is this what you want.

Resizing Div and its content dynamically to fit the browser height

I am trying to optimize my website to different screen and window sizes. I want the content of a div to take up 100% of the browser height, not more than that, so that the user doesn't have to scroll down. I am not sure how to implement this, I tried this
$(window).on('load resize', function(){
$('.container-narrow').width($(this).width());
$('.container-narrow').height($(this).height());
)};
But this doesnt seem to work, the content still goes over the browser height. and I have to endup scrolling
CSS will recalculate on resize.
<html>
<head>
<style>
body, html {
height: 100%;
margin: 0px;
padding: 0px;
}
.body {
height: 100%;
margin-bottom: -100px;
}
.header {
height: 100px;
background-color: #CCCCCC;
text-align: center;
}
.content {
text-align: center;
}
.footer {
height: 100px;
text-align: center;
background-color: #AAAAAA;
}
</style>
</head>
<body>
<div class="body">
<div class="header">
This is the header.
</div>
<div class="content">This is the content.</div>
</div>
<div class="footer">
This is the footer.
</div>
</body>

Why doesn't my sticky footer stick?

I've browsed to all question related to "sticky footer" and nothing helped me because my #content div does not always have sufficient content to push the footer to the bottom. Here is the code I've used to achieve this, but apparently I did something wrong:
html, body, div#container { height: 100%; }
body > div#container { height: auto; min-height: 100%; }
div#index_body { padding-bottom: 30px; }
.footer {
clear: both;
position: relative;
z-index: 10;
height: 30px;
margin-top: -45px;
padding-top:15px;
}
.footer {
color: #666;
background-color:#F4F7FA;
border-top:1px solid #E6E7E8;
font-size:95%;
text-align: center;
}
<div id="container">
<div id="index_body">
</div><!--end index_body -->
<div id="index_footer" class="footer">
</div><!--end footer -->
</div><!--end container -->
Some of my attempts work when index body has loads of text images only then the footer goes to the end but when it doesn't have much content let say 2 paragraph tags and an image the footer doesn't stick. Maybe this is not possible with just CSS, because the index_footer height is not fixed? Is there a way to do this with JavaScript? Or what is the right way to do this?
My screen resolution is really big maybe that is the problem its 1680 x 1050
Try moving your footer div outside of the container div. Your technique should then work. The way you have it set at the moment the footer is within the containing div, but positioned relatively. So even though the containing div may have 100% height, the footer div within it is still only to go just below the content in the container.
A quick example of what I mean, (note that an extra div with some padding-bottom is required in order to make sure the footer does not overlap the contents),
<html>
<head>
<title>Sticky Footer Test</title>
<style>
html, body {
height: 100%;
padding: 0px;
margin: 0px;
}
* {
margin: 0px;
}
#container {
min-height: 100%;
height: auto !important;
height/**/: 100%; /* for IE6 */
background: #ddd;
}
#footer {
position: relative;
background: #555;
margin-top: -100px;
height: 100px;
}
#content {
padding-bottom: 100px;
}
</style>
</head>
<body>
<div id="container">
<div id="content">
<p>Hello! I'm some content!</p>
</div>
</div>
<div id="footer">
<p>Hello! I'm a footer!</p>
</div>
</body>
</html>
If you can't move the footer outside of the container (for whatever reason), then you could also try positioning the footer absolutely within the containing div to be at the bottom. position: absolute; bottom: 0px; etc
For example, (again, an extra div with some padding-bottom is required in order to make sure the footer does not overlap the contents),
<html>
<head>
<title>Sticky Footer Test 2</title>
<style>
html, body {
height: 100%;
padding: 0px;
margin: 0px;
}
* {
margin: 0px;
}
#container {
position: relative;
min-height: 100%;
height: auto !important;
height/**/: 100%; /* for IE6 */
background: #ddd;
}
#footer {
position: absolute;
bottom: 0px;
width: 100%;
background: #555;
margin-top: -100px;
height: 100px;
}
#content {
padding-bottom: 100px;
}
</style>
</head>
<body>
<div id="container">
<div id="content">
<p>Hello! I'm some content!</p>
</div>
<div id="footer">
<p>Hello! I'm a footer!</p>
</div>
</div>
</body>
</html>
I know this doesn't answer your exact question, but the work done by Ryan Fait has worked very well for me across multiple browsers. You might want to give this a try (or take a look at what he did compared to what you are doing and see if you can determine a fix).
I believe the root of the problem is that the footer element in the HTML needs to be outside of the #container div. Also, I noticed after I removed that, issues with margin and padding on the body tag. Finally, the border-top on the .footer makes the height of the footer 46px, not 45px...
The corrected CSS:
/* FOOTER FIX */
html, body, div#container { height: 100%; }
body > div#container { height: auto; min-height: 100%; }
div#index_body { padding-bottom: 30px; }
body{margin:0;padding:0;}
#container{ margin-bottom: -46px; }
.footer {
clear: both;
position: relative;
z-index: 10;
height: 30px;
padding-top:15px;
color: #666;
background-color:#F4F7FA;
border-top:1px solid #E6E7E8;
font-size:95%;
text-align: center;
} /* END FIX */
The corrected HTML:
<html>
<body>
<div id="container">
<div id="index_body">
</div><!--end index_body -->
</div><!--end container -->
<div id="index_footer" class="footer">
</div><!--end footer -->
</body>
</html>
It's actually easy, here's the minimum required template:
<!doctype html>
<html lang="en">
<head>
<title>SO question 1980857</title>
<style>
html, body {
margin: 0;
height: 100%;
}
#container {
position: relative;
min-height: 100%;
}
* html #container {
height: 100%; /* This is min-height for IE6. */
}
#footer {
position: absolute;
bottom: 0;
}
#footer, #pushfooter {
height: 50px; /* Both must have the same height. */
}
</style>
</head>
<body>
<div id="container">
<div id="content">Content</div>
<div id="pushfooter"></div>
<div id="footer">Footer</div>
</div>
</body>
</html>
Making the container relative and giving it a min-height will actually stick the footer to its bottom all the time regardless of the content's actual height, which was your major concern as understood from comments.
Going off Harmen, i have tested this and it works, with the footer in the container. altho it is a little hackish
CSS
html, body, div#container { height: 100%; }
body > div#container { height: auto; min-height: 100%; }
div#index_body {
min-height: 100%;
margin-bottom: -46px;
}
.footer, .push {
height: 30px;
}
.footer {
clear: both;
position: relative;
z-index: 10;
margin: 0px;
}
.footer {
color: #666;
background-color:#F4F7FA;
border-top:1px solid #E6E7E8;
font-size:95%;
text-align: center;
} /* END FIX */
html
<body>
<div id="container">
<div id="index_body">
<div class="push"></div><!--Used to force the footer down to avoid overlap of footer and text -->
</div><!--end index_body -->
<div id="index_footer" class="footer">
</div><!--end footer -->
</div><!--end container -->
</body>
In order to realize a sticky footer, that is a footer placed in a fixed position at the bottom of the webpage that doesn't move when your scroll the page you can use this css code:
#footer{
position:fixed;
clear:both;
}
position:fixed makes the footer sticky anyway there could be floating problems if you used float:left or float:right in your code before, so using also clear:both it clears the floating and ensures that the footer is at the bottom under other divs and not on the left or right of the precedent div.
This will work, no matter what the height of the #container is:
CSS:
html, body {
height: 100%;
}
#container {
min-height: 100%;
height: auto !important;
height: 100%;
margin-bottom: -50px;
position: relative;
}
#index_footer {
height: 50px;
line-height: 50px;
position: relative;
background: #CCC;
}
#push {
height: 50px;
}
HTML:
<div id="container">
<div id="index_body">
test
</div>
<div id="push"> </div>
</div>
<div id="index_footer" class="footer">
test
</div>
