Tweet For Code #2

By  on  

You don't need a thousand lines of code to make a big difference in any coding language.  Oftentimes it's quite the opposite:  a few tiny code snippets can do a world of good and accomplish big things.  I asked my Twitter followers to tweet to me their favorite tiny snippets of code -- that's a bit difference to try to pack into 140 characters!  Here are my favorites from this round!

Comma-separated Lists without Server-Side Logic

Want to make a HTML list of items look like a real, comma-separated list?  Check this out:

I implemented this on my upcoming redesign with great effect, and used it on the MDN redesign.

Pure CSS Sliders

The following snippet use max-height to implement CSS-only sliders with overflow hidden:

I wrote about this a while back -- and awesome technique that too few developers know about.

You could do this with a number of properties, but this is a nice usage.

I had no idea what I'd see when I executed this into the JavaScript console, but I'll let it act as the conclusion to this post:

See you next time!  I can't wait to see what you all come up with next!

  1. MaxArt

    The first one can be achieved for IE8 too with some adjustments:

    ul > li:before { content: ","; }
    ul > li:first-child:before { content: none; }
    
  2. For the first tip, the good old (IE7 compliant) sibling selector is also perfect and requires only one rule:

    li + li {blabla}
    
  3. abhi

    How does this work?

    b = [a, a = b][0];
