I have a footer with dynamic content & height, so i'm using the display:table version of sticky footer. The problem is I have a menu with an absolute positioned drop-down that extends past the footer if the page is too small, menu too big, etc. This creates a gap below the footer. Check out the fiddle for an example. Thanks.

Here's the css, although its easier to see in the fiddle.
html, body {
height: 100%;
margin: 0;
}
.wrapper {
display: table;
height: 100%;
width: 100%;
background: yellow;
}
.content {
display: table-row;
height: 100%;
background: turquoise;
position:relative;
}
.menu {
position:absolute;
left:0;
width:50%;
background:yellow;
overflow:hidden;
max-height:20px;
}
.menu:hover {
max-height:1000px;
}
.menu li {
height:800px
}
.footer {
display: table-row;
background: lightgray;
}
.footer:hover h3 {
height:300px;
}
In your CSS, take position:absolute; out of the menu class and the footer will move down to accommodate the long menu. If you want the footer to remain at the bottom of the browser window, add the following into your footer class...
width:100%;
position:fixed;
bottom:0;
position:absolute; takes the element out of the document flow. The element is then positioned relative to its first positioned (not static) ancestor element. Taking it out of the menu class puts the menu back into the document flow and stops the menu overlapping the footer.

So here is a picture reference for this question:
What I would like to do is, using flexbox layout 3 columns (left side bar, center content, *optional right side bar). Basically, you have the 3 columns but only show the left side bar and content columns normally. Then, when the user clicks the menu button, have the right side bar content come into view (as shown by the red part in the drawing).
I figured the parent container to start would look something like:
body {
display: flex;
flex-flow: row nowrap;
justify-content: center;
align-items: stretch;
}
What else would be needed (especially for the right side push in sidebar) to get this working with flexbox?
You are so close.
In order to make the content column grow when the right sidebar is hidden, you need a positive flex-grow on it.
And in order to make the body cover all the screen, remove its margin and use height: 100% on both html and body.
Here is a working example:
document.querySelector('button').addEventListener('click', function() {
document.getElementById('right').classList.toggle('hidden');
});
html, body {
margin: 0;
height: 100%;
}
body {
display: flex;
flex-flow: row nowrap;
}
.sidebar {
width: 25%;
background: #777;
}
#content {
flex-grow: 1;
background: #000;
}
.hidden {
display: none;
}
<div id="left" class="sidebar"></div>
<div id="content">
<button type="button">Toggle sidebar</button>
</div>
<div id="right" class="sidebar hidden"></div>
Usually I vertically center a button, inside an absolute positioned div with top:50%, and margin-left:-(height/2), but today I realised it's not perfect, or I don't know how to use it correctly.
For example I did 2 examples. In the first example the <a> tag is an inline element, in the second example it's a block element. The positioning with block element is perfect, but unfortunately the width is 100%.
Please explain that why is the second example works well, with display:block;?
I'm really interested in your cross browser solution. How do you do this simple stuff?
Here is my css:
.container {
height:240px;
position:relative;
}
.box {
width:200px;
height:100%;
position:absolute;
left:0;
top:0;
background:yellow;
text-align:center;
padding:20px;
}
#example2 { left: 250px; }
.btn {
display:inline-block;
padding:5px 12px;
line-height:34px;
color:#fff;
background:red;
position:relative;
top:50%;
margin-top:-17px;
}
#example2 .btn { display:block; }
..and html
<div class="container">
<div id="example1" class="box">
button
</div>
<div id="example2" class="box">
button
</div>
</div>
The online version is available at http://jsfiddle.net/79hqgabq/2/
The alignment issue you see is being caused by the margin-top: -17px line as seen by this updated fiddle with that line removed on the .btn class: Updated Demo
On another note, vertical alignment is notoriously problematic with old CSS selectors, and it would be a good idea to transition over to Flexbox unless you needed to support older browsers.
Here's your problem with the new display: flex selector and corresponding sub-selectors: Demo w/ Flexbox. This removes the emphasis on having to pixel fudge to get proper vertical alignment.
New .box class
.box {
width:200px;
height:100%;
position:absolute;
left:0;
top:0;
background:yellow;
text-align:center;
padding:20px;
/* New lines for alignment */
display: flex;
align-items: center;
justify-content: center;
}
New .btn class (just removed the old tags)
.btn {
display:inline-block;
padding:5px 12px;
line-height:34px;
color:#fff;
background:red;
}
EDIT: After researching block elements have the property to expand to 100% of the parent container. This can be explained in more detail here. This is why display:block div expands until it reaches the padding on the .box class.
To answer why the display: inline-block element is slightly misaligned is because by default it is aligned on the baseline. See here for reference. Changing the vertical alignment of the div to be vertical-align: top will fix this.
Here is the new fiddle that uses all your previous syntax just with the added vertical-align: middle property.
Using the emenu Yii extension for a menu. The underlying project for this extension is http://lwis.net/free-css-drop-down-menu/ .
Right now the sub menus display in a row (which does eventually wrap to a 2nd row). I'm using the "nvidia" theme.
How do I make submenus vertical? I want the items in the sub menu to stack vertically on top of one another.
This is a css issue. The inner <ul> should have the style: width : 100% which comes from dropdown.css, but it is being overridden by themes/nvidia.com/default.css where it is specified as: width: 170px. So you can change that value back to 100% by adding it in your own custom css file.
dropdown.css:
ul.dropdown ul {
visibility: hidden;
position: absolute;
top: 100%;
left: 0;
z-index: 598;
width: 100%;
}
themes/nvidia.com/default.css:
ul.dropdown ul {
width: 170px;
background-color: #333;
color: #fff;
font-size: 11px;
text-transform: none;
filter: alpha(opacity=90);
-moz-opacity: .9;
KhtmlOpacity: .9;
opacity: .9;
}
mystyle.css:
ul.dropdown ul{
width:100% !important;
}
As you can see in the following Fiddle: http://jsfiddle.net/EvWc4/3/, I'm currently searching a way to align the second link (link-alt) to the right side of its parent (p).
Why not using float or position:absolute you'll say, well the main reason is that I like the fact that the links' display (inline-block) property allow them to be verticaly aligned in a naturally kind of way.
By using float or position:absolute; I'll be forced to calculate and put some extra margin-top or top value to vertically aligned the links.
Here is the code but better see the Fiddle http://jsfiddle.net/EvWc4/3/ :
<p>
link
link alt
</p>
p {
padding: 20px;
background: #eee;
}
.link {
display: inline-block;
padding: 10px;
background: #ddd;
}
.link-alt { padding: 20px; }
To do this with CSS3 you can use the flex box model
HTML:
<div class="content">
<div class="box box1"><a>Link 1</a></div>
<div class="box box2"></div>
<div class="box box3"><a>Link 2</a></div>
</div>
CSS:
.content {
display: box;
box-orient: horizontal;
box-pack: center;
box-align: center;
}
.box2 {
box-flex: 1;
}
(needs vendor prefixes)
http://jsfiddle.net/EvWc4/18/
CSS3 flex and grid items are supposed to address these issues, but standard support remains spotty as of 2013.
Back to the real world. I don't think it is possible to do this purely in CSS2.1 (IE8+) without pixel hacks. The thing is, text alignment is controlled by the parent element, and since the two anchors share their parent, they either both align to the left or to the right. And justify doesn't work on the last line.
If you can suffer a little additional HTML, there are two approaches:
1) Add another inline that is guaranteed to wrap the line, and then try to hide the empty line. This allows you to use text-align justify on the parent.
<p>
link
link alt
<span class="boom"></span>
</p>
<style type="text/css">
p {
padding: 20px;
background: #eee;
text-align: justify
}
.link {
display: inline-block;
padding: 10px;
background: #ddd;
}
.link-alt {
padding: 20px;
}
span {
display: inline-block;
height: 0;
width: 100%
}
</style>
Pros: works on any number of inline blocks, not just two. Only a little extra HTML required.
Cons: takes extra effort to hide the last (empty) line of text (setting the inline block inside of it to 0 height won't help you), and you're going to have to fiddle with margins or something else to make it really work. Further discussion: How do I *really* justify a horizontal menu in HTML+CSS?
2) Add another layer of inline blocks on top of your anchor tags and size them to 50%. Then you can apply separate text-align to get the final layout you requested. It is important that no whitespace is allowed between two inline blocks sized to 50%, or you'll wrap the line.
<p>
<span class="left">
link
</span><span class="right">
link alt
</span>
</p>
<style type="text/css">
p {
padding: 20px;
background: #eee;
}
.link {
display: inline-block;
padding: 10px;
background: #ddd;
}
.link-alt {
padding: 20px;
}
span {
display: inline-block;
width: 50%
}
.left {
text-align: left
}
.right {
text-align: right
}
</style>
Pros: produces the exact layout you requested without polluting the outer box model.
Cons: only works for two inline blocks (you can try to extend it, but it quickly gets really complicated). Relies on having no extra whitespace, which could jeopardize your nicely formatted markup.
You could set the position to absolute and use right: 0
.wrapper {
position: relative;
}
.right {
position: absolute;
right: 0;
}
http://jsfiddle.net/EvWc4/13/
I believe this accomplishes what you're looking for:
.link-alt {
position: absolute;
right: 0; top: 0; bottom: 0;
margin: auto;
max-height: 1em;
}
You can use position: absolute and right: 0 to obtain the right alignment. To keep the vertical centering, you can use top: 0; bottom: 0; margin: auto;. Of course, you'll also need to set a height on the element, or it will stretch to the full height of its parent.
Here's a jfiddle: http://jsfiddle.net/pHppA/
I've updated Pethas example, so it can be done in pure CSS2. It doesn't work in IE7, as it doesn't support display: table-cell; which I use.
http://jsfiddle.net/EvWc4/133/
The attribute float has no bearing on the element's vertical positioning.
p{padding:20px;background:#eee;overflow:auto;}
.link-alt{padding:20px; float:right}
should accomplish what you're looking for. Setting the overflow of the parent to something besides it's default (visible) will force it to treat floating children like normal elements.

I haven't tested this at all outside of Chrome, so it might suck for IE.
This simple (and limited) solution leverages text-align: right and width: 50% on the aligned children, and white-space: nowrap on the parent to achieve the desired result.
Example: http://jsfiddle.net/erikjung/ejcJZ/
.vertically-centered-module {
white-space: nowrap;
}
.vertically-centered-module > * {
display: inline-block;
vertical-align: middle;
width: 50%;
}
.vertically-centered-module > :last-child {
text-align: right;
}
I'm doing some tests on a website using Wordpress as a CMS. In the example below the top left of the page has an "S" graphic outside of the main content area, clipped accordingly depending on the browser width. I would like to do something similar with an "L" graphic to the right in the footer.
The page width is set to 960px, and I've made the footer container DIV 1088px so that the "L" appears outside the content area. The trouble is this makes a scrollbar appear when it exceeds the current width of the browser.
I've tried overflow:hidden on the footer container DIV but this doesn't seem to work. I've also tried overflow:hidden on the BODY element and this works ok in IE, but not in other browsers.
Example: http://unclemort.com/wp/
I really hope there is away to do this, any help gratefully received.
I was trying to figure this out myself today and stumbled upon the answer.
What you need is a surrounding element around everything that has this:
#wrapper {
min-width: 600px; //whatever width you want
overflow-x: hidden;
}
Your main content should have that same width, and the things that need to jut out should have a negative margin.
Here's a complete example:
HTML:
<div id="outer">
<div id="container">
<div class="row">
<div class="inner">Hello World</div>
</div>
</div>
</div>
CSS:
#outer {
min-width: 300px;
overflow-x: hidden;
}
#container {
width: 300px;
margin: 0px auto;
background: gray;
height: 500px;
}
.row {
width: 350px;
background: blue;
margin-left: -25px;
}
.inner {
background: yellow;
margin-left: 25px;
width: 300px;
height: 100px;
}
#media screen and (min-width: 301px) {
body {
//overflow-x: hidden;
}
}

Try in style.css, line 65, adding:
#footer-container {
border: none;
overflow: hidden;
}
Explanation:
#footer-container #footer {
background: #f5e8f7 url('images/slobraico-footer-pink-full.gif') no-repeat top left;
width: 1088px;
height: 217px;
overflow: hidden;
}
The scrollbar you're hiding is effectively not there.
The scrollbar you're seing is another one.
The problem is that the footer is 1088px wide, and that's causing a scrollbar to appear.
As long as the footer has fixed width and it's parent doesn't have overflow: hidden, you'll get a scroll if there's not enough width for the footer to fit.
Same goes for any other container.
