CSS Border Not Working

I've been trying to get a border on either side of my white conta开发者_如何学Goiner. It's just not showing. I've tried to put it in three different elements just in case! (see below). Any ideas on how to make it work?

#wrapper {
    width:1000px;
    background:#F4F4F4;
    padding-top:5px;
    border: 3px #CDCDCD;
    overflow: auto;
    min-height: 100%;
    height: auto !important;
    height: 100%;
    margin: 0 auto;  
}

#casing {
    padding:0px 0px 0px 0px;
    background:#Fff;
    border: 0 1px 0 1px solid #000;
}   

#cover {
    border: 0 1px 0 1px solid #000;
}   

Do this:

border: solid #000;
border-width: 0 1px;

I think you've just made up shorthand syntax for the border: property there =)

Try simply:

border-right: 1px solid #000;
border-left: 1px solid #000;

Use this line of code in your css

border: 1px solid #000 !important;

or if you want border only in left and right side of container then use:

border-right: 1px solid #000 !important;
border-left: 1px solid #000 !important;

Have you tried using Firebug to inspect the rendered HTML, and to see exactly what css is being applied to the various elements? That should pick up css errors like the ones mentioned above, and you can see what styles are being inherited and from where - it is an invaluable too in any css debugging.

AFAIK, there's no such shorthand for border. You have to define each border separately:

border: 0 solid #000;
border-left: 1px solid #000;
border-right: 1px solid #000;

The height is a 100% unsure, try putting display: block; or display: inline-block;

You forget to add Border style, Do this

border-style: solid

Or you can write

border: 3px #CDCDCD solid

In latest version, i just experienced to get a border you have to first set the border-style. Then, the rest border width or color is considered.

border-style: solid;
border-width: 2px;
border:blueviolet;

Check if somewhere in a code you are not using this style:

border-top: none;

Or any other variation of border-{side}: none.

You cannot shorthand concept in the border. Simply use :- borderWidth: '1px', border: 'solid #BDBDBD' // This is color which u can as per ur need.
