Centering Div


Very nice, crossbrowser method for div centering both horizontally and vertically.
Just use this css:

#centeringDiv {
  top: 50%;
  left: 50%;
  width:20em; /* width value */
  height:20em; /* height value */
  margin-top: -10em; /* minus 1/2 of your height */
  margin-left: -10em; /* minus 1/2 of your width */

Another smart centering option using float and clear.

If you as me like an elastic or flexible designs, I like to introduce you YAML (”Yet Another Multicolumn Layout”) - XHTML/CSS–framework developed for creating a flexible and user-friendly layouts. We all know of the importance of flexible layouts as there are millions screens out there: mobile, handhelds, WebTV, etc. Flexible design (as here at SEO Freelancer) simplifies life. Watch demonstration of YAML-based design. Simple, elegant, cross-browser compliant. And flexible.

AJAX Generated Nofollow


As you can see I've got a SEO Resources page with tons of links. Recently I've decided to insert 'nofollow' tag into every link on that page.

As there are over 1500 useful listed resources editing urls by hand would be immence waste of time. So, I've decided to use magic of AJAX. That looked impressive and realistic. The idea was simple - to find div by id containing tag <a> and to add rel='nofollow'. Mechanism for this purpose looked like this:

  • var links = document.getElementById(id).getElementsByTagName('a');
  • for (var i=0; i
  • links[i].rel = "nofollow"
  • }

Dreams, dreams... The end of this story is negative, because searchbot can't run AJAX :(
