Height of containing div with overflow-y: hidden not expanding with content - html

So I have 3 divs contained inside a containing div like such:
<div id="contain">
<div id="leftnav">
....
</div>
<div id="todo">
...
</div>
<div id="rightcontent">
....
</div>
</div>
The css is as follows:
div {
-webkit-box-sizing: border-box; /* Safari/Chrome, other WebKit */
-moz-box-sizing: border-box; /* Firefox, other Gecko */
box-sizing: border-box; /* Opera/IE 8+ */
}
#contain {
width: 1000px;
background: #ffffff;
display: block;
min-height: 500px;
height: auto;
max-height: 1500px;
overflow-x: hidden;
overflow-y: auto;
position: relative;
border-bottom-right-radius: 10px;
border-bottom-left-radius: 10px;
}
#leftnav, #todo {
float: left;
width: 20%;
display: block;
overflow: hidden;
height: 100%;
padding: 10px;
position: absolute;
left: -200px;
bottom: 0;
}
#rightcontent {
float: right;
width: 100%;
display: block;
position: absolute;
right: 0;
top: 0;
padding: 10px;
}
Now, the reason the #leftnav and #todo are positioned the way they are is because they are being animated to the right based upon their left value if the user clicks on the link, and the right content is just shown all the time. However, this is where the problem comes in.
I need the containing div to expand in height based upon the content in the #rightcontent div up to the max-height. As it stands, it is simply constantly keeping the height at 500px no matter what, and implementing scroll bars (which I do not want to have occur). Maybe I am approaching this all wrong, and putting an overflow: hidden on it still keeps it set to 500px no matter what.
I can provide more info if needed. Thanks in advance.

Looks like you have a problem with floats. When you float elements they break out normal rendering flow. Just as a test add float:left to your #contain div. You should see it expand to contain its children divs.
I generally try to avoid using floats for this very reason.

CSS container height issue

My container is not touching my footer for the majority of cases and I'm not sure what's going on.
So here is my CSS code:
html {
min-height: 100%;
position: relative;
}
body {
margin: 0;
width: 100%;
height: 100%;
}
section {
height: 100%;
}
#container {
overflow: auto;
width: 80%;
margin: 0 auto;
background: red;
height: 100%;
}
.footer {
width: 100%;
position: absolute;
left: 0;
bottom: 0;
}
Here's my HTML:
<body>
<div id="container">
<section>
<p>Content goes here</p>
</section>
</div>
<div class="footer">Content</div>
</body>
So I have all of the heights set for parent elements,but there's still a big gap between the container and the footer. In cases where the content takes up the whole page, the footer and container ends up touching, but the content for some reason gets lost in the footer. How can I solve this issue?
Height based on percentage are tricky. vh is much better for such purposes.
Here is the solution: JSfiddle
#container {
overflow: hidden;
width: 80%;
margin: 0 auto;
background: red;
height: 100vh;
}
Make one adjustment to your CSS:
Add height: 100% to the html element.
html {
height: 100%; /* NEW */
min-height: 100%;
position: relative;
}
This will clear the way for all child elements to recognize their percentage heights, and the container will expand. Your min-height: 100% will still work because min-height overrides height.
DEMO: http://jsfiddle.net/au6tcodc/
(You'll notice a vertical scrollbar on the container in the demo. This is caused by the overflow: auto declaration in #container. If you want to remove the scrollbar switch to overflow: hidden (see all overflow values).

Mysterious white space outside of HTML flow?

I have a simple div wrapper with four spans inside.
<body>
<main>
<div>
<span>One</span>
<span>Two</span>
<span>Three</span>
<span>Four</span>
</div>
</main>
</body>
The div is positioned absolutely so that I can get it to touch the bottom of the screen, and text-align is justify so the spans inside are evenly spaced. This works fine until I try to make my spans height: 100%, then a mysterious white space appears outside of the actual flow on the very bottom. I think this has something to do with my div:after psudo-element but I have absolutely no idea what's going on.
* {
padding: 0;
margin: 0;
}
main {
position: relative;
height: 100vh;
width: 100%;
background-color: rgb(45, 45, 65);
text-align: center;
}
div {
position: absolute;
top: 50%;
left: 25%;
right: 25%;
bottom: 0;
text-align: justify;
display: block;
}
div:after {
display: inline-block;
width: 100%;
content: '';
}
span {
background-color: rgb(25, 25, 45);
box-sizing: border-box;
display: inline-block;
font-size: 1em;
padding: 10px;
height: 100%;
}
span:hover {
background-color: white;
}
Do I not understand how :after works, or is this some kind of a glitch? Where in the world is that white spacing coming from on the bottom?
Here's a reproduction of the problem: http://codepen.io/anon/pen/qdpERR?editors=110
simply add an overflow: hidden; to the main or even the parent of the main should works.
Check the link
http://codepen.io/TibicenasDesign/pen/yNpyLr?editors=110
Uncomment overflow: hidden; or box-sizing: border-box then, the white space at the end of the web will be removed.
Also the box-sizing works ! i always have it with border-box so forgot it haha, and maybe its a better solution
Another option may be to add box-sizing:border-box, becauase you have padding on those link elements.

Vertical align middle div inside div

Examining this HTML:
<div class="wrapper">
<div class="content">
</div>
</div>
<div class="footer">
<hr />
<p>some text</p>
</div>
and CSS:
.footer {
position: absolute;
height: 100px;
width: 100%;
bottom: 0;
background-color: black;
}
.wrapper {
padding-bottom: 100px;
background-color: blue;
height: 100%;
}
.content {
width: 200px;
height: 100px;
margin: auto;
background-color: green;
}
html, body {
width: 100%;
height: 100%;
}
You can see that footer have position absolute and stay at the bottom of the page. wrapper will cover the remaining space and contain a content inside it. I want to vertical-align content without breaking the current layout. Do you have any suggestion?
Here is JSFiddle link. (Note: jsfiddle doesn't work as expected, there always a space beneath footer, this behavior doesn't occur when run the HTML file in browser).
Note: I don't want to use fixed height for wrapper, I want it covers all the remaining space, so please don't suggest me to use line-height
I tried the example here but it doesn't seem to work
NOTE I want the layout easy to modify (like add a header or content at the top) without breaking it therefore I want to avoid using absolute position on wrapper and content
NOTE 2 Sorry for not to clarify, actually, content doesn't have fixed size, its size depend on the content inside it, so the solution using negative margin doesn't work as I mentioned above
Here is one approach using the following CSS:
.footer {
position: absolute;
height: 100px;
width: 100%;
bottom: 0;
background-color: black;
}
.wrapper {
background-color: blue;
position: absolute;
top: 0;
bottom: 100px;
left: 0;
right: 0;
}
.content {
width: 200px;
height: 100px;
background-color: green;
position: absolute;
top: 50%;
left: 50%;
margin-top: -50px;
margin-left: -100px;
}
html, body {
width: 100%;
height: 100%;
margin: 0;
}
Use absolute positioning and then negative margins, since your content has well-defined
dimensions, this is relatively straightforward.
See demo at: http://jsfiddle.net/audetwebdesign/DgUV2/
For .wrapper, use the top, bottom, left and right offsets to stretch the div to the
full width and height, taking into account the 100px for the footer.
For .content, set top and left to 50%, the center point of the .wrapper and then adjust
for the center of the .content div using negative margins.
Remember to zero out the margin for the body or else you might see 10px whitespace
depending on your browser.
Add this to your .content
position: relative;
top: 50%;
transform: translateY(-50%);
Just 3 lines of code to vertical align
I was able to get it to work using Method 1 from the example you linked
I added the following:
.content {
width: 200px;
height: 100px;
margin: auto;
background-color: green;
/* THE BELOW WAS ADDED */
position: absolute;
top: 50%;
left: 50%;
margin: -100px 0 0 -100px;
}
html, body {
width: 100%;
height: 100%;
/* BELOW ADDED TO REMOVE EXTRA SPACE AROUND EDGES */
margin: 0;
}

CSS - header to stay in top of container

I have this container which can scroll the content. I would like the header in this container to always stay in the top.
http://jsfiddle.net/z9ze5/
Container:
.lists {
width: 300px;
height: 250px;
margin: 30px auto;
background: #39C;
overflow: scroll;
position: relative;
}
Header:
.box_header {
width: 100%;
height:30px;
overflow:hidden;
position: absolute;
margin: 0;
background: #DDD;
z-index: 999;
}
If you are willing to alter your mark-up, here is one way of doing it:
<div class="lists">
<header class="box_header">
<h1>HEADER 2</h1>
<div class="setting" id="btn2"></div>
</header>
<section class="content">
<p>Lorem Ipsum ....</p>
</section>
</div>
Wrap your scroll area in a <section> (or other block level element).
For your CSS:
.lists {
width: 300px;
height: 250px;
margin: 30px auto;
background: #39C;
position: relative;
}
section.content {
width: 300px;
height: 220px;
margin: 0 auto;
background: #39C;
position: relative;
top: 30px;
overflow: scroll;
}
Please see fiddle: http://jsfiddle.net/audetwebdesign/nGGXx/
More Advanced Example
If you study the following example:
http://jsfiddle.net/audetwebdesign/fBNTP/
uou can see how your scrolling boxes could be applied in a semi-flexible layout.
I lined up two scrolling boxes side by side and made their width proportionate to the width of the page.
The height is trickier to adjust. I fixed the height of the parent container, see the following rule:
.contentWrapper {
border: 1px solid red;
margin-top: 1.00em;
padding: 30px 0;
overflow: auto;
height: 400px;
}
If you change the height from 400px to some other value, the scrolling boxes will adjust themselves.
Hopefully, these examples will give you and others some more insights into how to build these more advanced layout designs.
If you want a non-css fix, add this listener...
$('.lists').scroll(function() {
$('.box_header', this).css('top', $(this).scrollTop()+'px');
});
and then change .lists css to give relative positioning
.box_header {
width: 100%;
height:30px;
overflow:hidden;
position: relative;
margin: 0;
background: #DDD;
z-index: 999;
}
Any position absolute within a position relative is absolute to the relative container. In order to have a header that stays in position, you'd need to position it above, not within, the scrolling container.
look at adding position: fixed to your header div .box_header. You may have to add padding of the height of the box header div to section.content but as you have that set to 30px that should be fine. IE6 and lower has issues with fixed positioning but hopefully we can live with that now - less people are using that than are still listening to Moby.

Container not resizing for child div

Click here for visual
As you can see from the picture, my parent container is not expanding to fit my child container. The page container (#contain) actually stops at the bottom left hand corner of the kitchen photograph. The child container (#zone2) is clearly overflowing outside its parent container (#contain). I would like to be able to have (#contain) expand automatically to fit (#zone2). The CSS is:
#contain {
position: relative;
width: 100%;
margin: 0 px;
background: #E3DCCC;
z-index: 0;
}
#zone1 {
width: 100%;
height: 850px;
background: url(http://waly1039.com/sites/default/files/k4.jpg) no-repeat center top;
position: absolute;
z-index: -1;
}
#head {
position: absolute;
top: 20px;
width: 100%;
height: 330px;
}
#head img {
max-width: auto;
height: auto;
}
#zone2 {
position: relative;
overflow: hidden;
padding: 3px;
top: 360px;
float: right;
right: 15px;
width: 53%;
height: auto;
border: 4px solid #715E40;
background-color: white;
}
#zone2 img {
max-width:100%;
height: auto;
float:left;
margin: 5px;
}
#zone3 {
position: relative;
top: 710px;
left: 15px;
float: left;
height: 340px;
width: 38%;
border: 4px solid #715E40;
background-color: white;
}
This is a float issue. Try adding the traditional CSS clear fix to #zone2's container:
.container:after{
visibility: hidden;
display: block;
font-size: 0;
content: " ";
clear: both;
height: 0;
}
Be sure to put this in the :after pseudo selector, otherwise it won't work for you. Floated elements exist outside of normal document flow, which is why the container isn't expanding to contain them. The clear fix forces the floats to be cleared, which will cause the container to expand around the bottom of this element.
I tested adding more images to #zone2 and #contain expands vertically. Somehow you've got an element(s) in #zone2 with padding or margins that aren't being added to the parent's total height.
If you want a quick fix in order to move on then add margin-bottom: 30px; to #zone2.
I've duplicated your problem and was able to resolve it with this: You might want to try it. It's looks a bit odd so make a class for it if you like. I'm more concern with where it is placed.
Just beneath lines of your code, add my third line. Just that and you are done. Note, it more about positioning.
<div id="zone3"></div>
<div id="zoneclear"></div>
<br style="clear:both; float:none; display:block; height:1px;" />
Just add the third line.
and just modify one of your styles:
#zoneclear {
clear: both;
float:none;
display:block;
height: 30px;
position: relative;
}
[EDIT]
The codes have a serious bug in firefox which is not present in Google Chrome (that I tested in earlier due to your relative positioning. So I've modified the #zoneclear style to fix that. You might have to test if the other browsers like this hack.
I hope it helps you
