CSS horizontal menu - equally spaced?

问题

I have a standard CSS menu, made with UL and LI tags. I need them to get to cover the whole page, horizontally (not my real case, but I'll take this to simplify the situation). However, the items are created dynamically and so I'm not able to hardcode any with to LI items, nor margins.

I've seen solutions using JavaScript to set those values but I would really love to avoid them.

Lastly, I've seen a pretty good solution which is setting

#menu {
    width: 100%;
    /* etc */
}
#menu ul {
    display: table;
}
#menu ul li {
    display: table-cell;
}

This will create the desired behavior in most browsers... except for IE.

Any ideas?

EDIT: Thanks for the responses. However, as the code that generates the items isn't mine, I'm not able to set inline styles when creating them without using JavaScript later.

You can't set the height or width of an inline element. http://www.w3.org/TR/CSS2/visudet.html#inline-width

Try display:inline-block;

here is the fix for ie:

display:inline-block;
zoom:1;
*display:inline;

If you want to let the element get the whole available space, there is no need to define a priori the width of the menu elements (of course, it will help in equally sizing the li elements). You can solve this problem by working on the display property.

#menu{
  display: table;
  width: 100%;
}

#menu > ul {
  display: table-row;
  width: 100%;
}

#menu > ul >li {
  display: table-cell;
  width:1%
}

Note that width:1% is required to avoid cell collapsing.

If your menu items are being dynamically generated (so you don't know how many there will be prior) then you can add a style="width:xx" attribute to the lis (or in <style> at the top... or where ever you please, really). Where xx should either by width_of_parent_div_in_px/number_of_elements+'px', or 100/number_of_elements+'%'. The lis should also be block-level elements, and floated left.

#menu ul li {
    float: left;
    clear: none;
    display: inline;
    padding: 10px;
    height: 25px; //how tall you want them to be
    width: 18%; //you will need to set the width so that all the li's can fit on the same line.
}

The width: 18% may be about right if you have 5 elements across, accounting for border and padding. But it will vary due to how many elements you have, how much padding, etc.

If you are open to using Flexbox then it isn't hard to do. Full credit for the code I am about to post goes to CSS Tricks as this is their CSS.

Below is an example that includes vendor prefixes.

#menu{
  
  list-style: none;
  
  -ms-box-orient: horizontal;
  display: -webkit-box;
  display: -moz-box;
  display: -ms-flexbox;
  display: -moz-flex;
  display: -webkit-flex;
  display: flex;
  -webkit-justify-content: space-around; 
  justify-content: space-around; 
  
 }

<ul id="menu">
  <li>Home</li>
  <li>Store</li>
  <li>Blog</li>
  <li>About</li>
  <li>Contact</li>
</ul>

The only issue with Flexbox is if you need to support IE 9 and below, otherwise, I see no reason to not use Flexbox. You can view browser support for Flexbox here.

Here's what worked for me:

#menu{
    height:31px;
    width:930px;
    margin:0 auto;
    padding:3px 0px 0px 90px;
    color:#FFF;
    font-size:11px;
}
#menu ul{
    display:inline;
    width:930px;
    margin: 0 auto;
}
#menu ul li{
    list-style:none;
    padding:0px 0px 0px 0px;
    display:inline;
    float:left;
    width:155px;
}
