Q:

Hide Text with CSS, Best Practice?

Let's say I have this element for displaying the website logo:
<div id="web-title">
  <a href="http://website.com" title="Website" rel="home">
    <span>Website Name</span>
  </a>
</div>

The #blog-title would be styled with background:url(http://website.com/logohere.png), but how to properly hide the text Website Name? As seen here: Hide text using css or here https://stackoverflow.com/a/2705328 , I've seen various methods to hide the text, such as:
#web-title span { text-indent: -9999px; }

or
#web-title span { font-size: -9999px; }

or 
#web-title span { position: absolute; top: -9999px; left: -9999px; }

I've also seen some combine those three methods. But actually which one is the best practice to hide text effectively?

A:

Actually, a new technique came out recently. This article will answer your questions: http://www.zeldman.com/2012/03/01/replacing-the-9999px-hack-new-image-replacement
.hide-text {
  text-indent: 100%;
  white-space: nowrap;
  overflow: hidden;
}

It is accessible, an has better performance than -99999px.
Update: As @deathlock mentions in the comment area, the author of the fix above (Scott Kellum), has suggested using a transparent font: http://scottkellum.com/2013/10/25/the-new-kellum-method.html. 

A:

you can simply make it transparent
{
   width: 20px;
   height: 20px;
   overflow: hidden; 
   color:transparent;
}

A:

Can't you use simply display: none; like this
HTML
<div id="web-title">
   <a href="http://website.com" title="Website" rel="home">
       <span class="webname">Website Name</span>
   </a>
</div>

CSS
.webname {
   display: none;
}

Or how about playing with visibility if you are concerned to reserve the space
.webname {
   visibility: hidden;
}
