Fluid layout with even width navigation items - css

I'm building a site for mobile devices and therefore has a fluid layout.
My navigation list looks like this:
<ul>
<li>home</li>
<li>about</li>
<li>work</li>
<li>contact</li>
</ul>
Problem is, the first list item needs to be 100px only (left aligned always), and the other 3 split evenly, therefore is it possible to have even width for all list items except for the first one (without using javascript).

This is the simplest way I could think of:
ul { overflow: hidden; padding-left: 100px; position: relative; }
li { width: 33.33%; float: left; }
li:first-child { position: absolute; top: 0; left: 0; width: 100px; }
The main idea is taking the first li out of the flow (position: absolute) and adding a padding-left to the ul (space for the first li). Now if we set the percentage width for the other lis, they will take up the remaining space.
And here is a jsFiddle Demo. I added a red border on the ul which shows that because of the percentages lis will not accurately fill it.
I am unsure what mobile browsers you want to support, but except :first-child (which can be worked around by adding a class on the first list item) I assume they must support everything I used.

hmm a bit cludgy - but this seems to work, it does require nesting the list (second 3 links in separate list) and a span for the "home" link, theory is that you need the first link to float, width: 100px, then you need the second group not to float and have their overflow hidden so the group take up the remaining space.. then you float the 3 links # 33% inside the non-floated container
Example : HERE
CSS:
div {
width: 90%;
margin: 0 auto;
}
ul {
margin: 0; padding: 0; list-style: none; /* reset */
float: left;
width: 100%;
}
li {
float: left;
width: 100%;
text-align: center;
}
li span {
float: left;
width: 99px;
background: #eee;
border-right: 1px solid #000;
}
ul ul {
float: none;
overflow: hidden;
width: auto;
}
li li {
width: 33%;
background: #ffe;
border-right: 1px solid #000;
}
HTML:
<div>
<ul>
<li><span>home</span>
<ul>
<li>about</li>
<li>work</li>
<li>contact</li>
</ul>
</li>
</ul>
</div>

For what it's worth, this was what I was thinking of when I made my comment on your question:
http://jsfiddle.net/4t9fV/
ul {
display: table;
width: 100%;
background: #ccc;
table-layout: fixed
}
li {
display: table-cell;
text-align: center;
outline: 1px dashed red
}
li:first-child {
width: 100px
}

How to make an on-hover bottom border overlap div below?

I have a horizontal navigation menu using unordered lists. Under the menu there is a straight gray line which has to have 100% width of the parent container. When hovering the list elements, the part of the line has to be colored blue right under the list element. I can't find any suitable way of doing this. I got it working with position:relative and adding top:14px but it isn't really satisfying me since any changes to the font size or font face will destroy everything. I also thought about changing margins between elements to padding, increasing li's height and giving each one the same gray border and just changing it's color on hover, but I need the line to go all along the parent div's width.
How it has to look:
expected result
My current code:
#container {
width: 80%;
margin: auto;
background-color: white;
}
#container ul {
list-style-type: none;
display: inline-block;
margin: 0;
padding: 0;
margin-top: 5px;
margin-bottom: 10px;
}
#container ul li {
float: left;
margin-left: 20px;
}
#container ul li:first-child {
margin-left: 0;
}
#container ul li a {
text-decoration: none;
color: black;
}
#container ul li a:hover {
color: grey;
}
#container #slider {
display: inline-block;
height: 5px;
background-color: #f1f1f1;
width: 100%;
}
<div id="container">
<ul>
<li>INDEX</li>
<li>HELP</li>
<li>LONG LINK TEXT</li>
</ul>
<span id="slider"></span>
</div>
JSFiddle: https://jsfiddle.net/9fhvyk76/3/
You'll want to use a pseudo element so you have more control over the size/position without really needing to change much. Just add position: relative to the link itself so the pseudo's scale and positioning are associated with it. Let me know if this is what you were looking for!
https://jsfiddle.net/g00jrsqf/
#container ul li a{
position: relative;
}
#container ul li a:after{
content: '';
position: absolute;
display: block;
width: 100%;
height: 4px;
background: #01a2e8;
opacity: 0;
left: 0;
bottom: -29px;
}
#container ul li:hover a:after{
opacity: 1;
}

Aligning list items with title

I'm trying to center and unordered list perfectly with the title of my website the title on top with the UL elements centered underneath.
The problem is that it does center, but not perfectly aligned with the overhead title. It is slightly to the right.
Here is my code:
.title{
text-align: center;
}
nav{
display: block;
margin-left: auto;
margin-right: auto;
width: 50%;
background: blue;
}
li {
text-align: center;
display: inline-block;
list-style-type: none;
margin: 0;
padding: 0;
background: red;
}
ul {
padding: 0;
}
The slight right-side bias is because of the default padding the entire list gets, not the individual list items. Setting it to zero eliminates the unnecessary offset.
I have to guess the HTML, but most likely you have a <ul> inside your <nav> element. Use this CSS:
nav > ul { margin-left: 0; padding-left: 0; }

How do I vertically align text inside an anchor element, which is nested within an unordered list

I have searched extensively and seen numerous examples on how to vertical-align text using the vertical-align property and the line-height property. However, all my efforts seem to bear no fruit as I am unable to get my text to align vertically. How do I do vertically align text to be centered? The height properties are not fixed so I can't use line-height.
HTML
<nav>
<ul>
<li>Login</li>
<li>Register</li>
<li>Programmes Offered</li>
</ul>
</nav>
CSS
nav
{
height: 30%;
width: 100%;
}
nav ul
{
height: 100%;
margin: 0px;
}
nav ul li
{
height: 33%;
width: 100%;
vertical-align: middle;
}
you may use a pseudo element displayed as an inline-box using full height of li and vertical-aligned to midlle. DEMO
body, html {
height:100%; /* needed for demo */
}
nav {
height: 50%; /* increased for demo */
width: 100%;
}
nav ul {
height: 100%;
margin: 0px;
}
nav ul li {
height: 33%;
box-shadow:inset 0 0 0 1px; /* show me li , for demo */
}
nav ul li:before {
content:'';
height:100%;
display:inline-block;
vertical-align: middle;
}
edit
If you also reset display and vertical-align on <a>, links can be spread on a few lines (demo below):
body,
html {
height: 100%;
}
nav {
height: 70%; /* height set for snippet demo purpose, could be really too much */
width: 100%;
}
nav ul {
height: 100%; /* will follow height, inherit height value , set in nav if any avalaible */
margin: 0px;
}
nav ul li {
height: 33%;
/* see me and my center*/
box-shadow: inset 0 0 0 1px;
background:linear-gradient(to top, rgba(0,0,0,0.1) 50%, rgba(0,0,0,0.2) 50%);
}
nav ul li:before {
content: '';
height: 100%;
display: inline-block;
vertical-align: middle;
}
a {
display: inline-block;
vertical-align: middle;
}
<nav>
<ul>
<li>Login
</li>
<li>Register
</li>
<li>Programmes<br/> Offered
</li>
</ul>
</nav>
If you can use flexbox, you can get away with the following css:
CSS
ul li a {
display:flex; // Enables flexbox
justify-content: center; // Center on main axis
align-items: center; // Center on cross axis
}
Update ( using auto margins )
You can also do it like this:
ul li { display:flex }
li a { margin: auto }
/* These rules are just to make things easier to see. */
nav {
margin: 0 auto;
margin-top: 5rem;
border: 1px dotted green;
width: 100%;
}
ul {
padding: 0;
display: flex;
justify-content: space-around;
}
li {
height: 3rem;
padding: 2rem;
border: 1px dotted red;
}
/* Here are what I am trying to illustrate */
ul li {
display: flex;
}
a {
margin: auto;
/* or adjust them one by one, by targeting
the ones you want and setting
using each margin like this:
margin-top: auto;
margin-right: auto;
margin-bottom: auto;
margin-left: auto;
*/
}
<nav>
<ul>
<li>Login</li>
<li>Register</li>
<li>Programmes Offered</li>
</ul>
</nav>
vertical-align aligns inline elements with their siblings.. unless used in a table cell.
I don't think there's a by-the-book way of vertically aligning.. but this should work:
D E M O
nav ul li
{
background:#f1f1f1;
height: 33%;
width: 100%;
border-top:1px solid #e0e0e0;
}
nav ul li a
{
display:block;
position:relative;
top:50%;
-webkit-transform:translate(0,-50%);
-moz-transform:translate(0,-50%);
transform:translate(0,-50%);
}
Have you tried with
nav ul li a
{
height: 33%;
width: 100%;
vertical-align: 5px; //(you can make it 10px or -10px, just so it fits your style)
}
Your text is within the a tag, so adding a in the css may solve your problem :)

unable to set Overlays in List items using css

i am working on this grid gallery where List items are set to width 20% so that they can be like 5 in one row using float left.
Now i am using a div with class overlay so that hen someone hovers over Li the overlayis shown.
the problem is
when i give overlay 100% width and height 100% it covers the whole screen and not just that Li.
here is my HTML code
<ul id="thumbsList">
<li>
<div class="overlay">Hello</div>
</li>
<li><div class="overlay">Hello2</div></li>
</ul>
And here is my Css
#thumbsList {
margin: 0px;
padding: 0px;
}
#thumbsList li {
list-style: none;
float: left;
height: 100px;
width: 20%;
background-color: gainsboro;
}
.overlay {
text-align: center;
z-index: 2;
height: 100%;
width: 100%;
position: absolute;
background-color: red;
}
Please help me fix the problem.
thanks.
You need to add position: relative to the li item, the absolute positioning in the overlay wil take this as reference.
#thumbsList li {
position: relative;
list-style: none;
float: left;
height: 100px;
width: 20%;
background-color: gainsboro;
}
Also you need to add a display: none to the overlay and a hover on li that change the display: none to display: block on the overlay, like this:
#thumbsList li:hover .overlay {
display: block;
}

CSS List Question

I'm looking for a quick cross browser solution to my need for auto margins.
I have a simple list:
<ul>
<li>text</li>
<li>text</li>
<li class="possibly_last">text</li>
</ul>
With a width of 600px.
What I need is CSS code to make sure there is an even margin between each <li>.
So that they stretch across the full 600px evenly.
I may need to as a "last" class, but that's fine.
I just want a browser friendly way to do this.
Any help would be great, Thanks!
Try this:
<style>
li {
display: block;
float: left;
width: 32%;
}
</style>
If that does not work, try this:
<style>
li {
display: block;
float: left;
width: 200px; // or less
}
</style>
I take it you mean you don't want a margin after the last li? In that case, use the CSS :last-child selector:
ul li
{
margin-right: 10px;
width: 190px; // 190px = 200px - margin width
display: inline-block;
zoom: 1;
*display: inline;
}
ul li:last-child
{
margin-right: 0px;
}
Please note that this will NOT work in any internet explorer except IE9. Sorry :-(
As a fix, you could use JavaScript (notably jQuery) to edit the CSS of the last child.
An example here: http://jsfiddle.net/WtLAm/2/
Are you intending to float the list items so they stretch horizontally to fill the ul that way? if so, something like
<style type="text/css" media="screen">
ul {width: 600px;}
li {display: inline; float: left; width: 33%;}
</style>
would work.
I think this can't be done with margins, I suggest you this solution:
http://jsfiddle.net/wY5t6/
css:
ul li {
margin: 0;
display: block;
float: left;
width: 200px;
text-align: center;
}
ul {
width: 600px;
overflow:hidden;
}
If you need to set padding, background etc on list item than you can do it this way:
http://jsfiddle.net/wY5t6/1/
HTML:
<ul>
<li><span>text</span></li>
<li><span>text</span></li>
<li class="possibly_last"><span>text</span></li>
</ul>
CSS:
ul li {
margin: 0;
display: block;
float: left;
width: 200px;
text-align: center;
}
ul {
border: 1px green dotted;
width: 600px;
overflow:hidden;
}
li span {
background: yellow;
padding: 5px;
}
