Errors when validating CSS

Hi All

I am getting errors when validating my css file with W3c.  I have attached a copy of my error output and css so you can see them.  

Not sure if I should just ignore them or get my web developer to fix.  Maybe if it is a easy fix I can do it?

Cheers

Si

It's because you can just use the border-radius now and don't need to add the vendor prefix.  It is fine as is or you can take it out.  This is not something to obsess over.

Most of the errors are harmless.  The first 8 errors should be ignored.  Leave that code there for maximum browser compatibility.   The last error (the parse error) is a problem.

You should totally remove this line from your CSS file:
<style type="text/css">

Understanding Web Applications

Without even knowing it, most of us are using web applications on a daily basis. Gmail and Yahoo email, Twitter, Facebook, and eBay are used by most of us daily—and they are web applications. We often confuse these web applications tools for websites.  So, what is the difference?

#nav li ul {
	position: absolute;
	width: 135px;
	left: -999em;
	top: 68px;
	margin:0;
	padding:0;
	list-style-type: none;
	background-color: #0661ec;
	background-color: rgba(6,97,236,0.8) !important;
	border: 1px solid #fff;
	border-top:none;
        /* comment out these 4 lines 
	-webkit-border-bottom-right-radius: 3px;
	-webkit-border-bottom-left-radius: 3px;
	-moz-border-radius-bottomright: 3px;
	-moz-border-radius-bottomleft: 3px;
        */
	border-bottom-right-radius: 3px;
	border-bottom-left-radius: 3px;
}

If you remove or comment out these lines:

      -webkit-border-bottom-right-radius: 3px;
      -webkit-border-bottom-left-radius: 3px;
      -moz-border-radius-bottomright: 3px;
      -moz-border-radius-bottomleft: 3px;

then the CSS will not work on old versions of Firefox or Chrome.  I would leave those lines unchanged.

However, you should totally remove this line from your CSS file:
<style type="text/css">

The border radius should work on all browsers except ie8 and lower.  I think even google stopped supporting ie8 in 11/2012.    You no longer need the vendor prefix.  Like I said, it is not worth obsessing over the error if you leave it in.
