   Greets:

   Silly question about CSS. I'm looking at a CSS file and am wondering when you use the # marks, when you use the periods and when you don't use anything at all in front of the lines.

   Thanks,
   -drmike

   Told you I didn't know anything about CSS :)

   # = id
   An id can only be used once.

   . = class
   You can use classes as often as you need and in different ways

   [blank] = just a regular declaration

   --

   #box {-details-}
   <div id="box">
   You can only have one such box used once on a page.
   </div>

   .text2 {-details-}
   <div class="text2">This could be used here</div>
   then we have some other text
   <div class="text2">and we use that styling again here</div>

   h3 {font-size: 10px;}

   .bigger {font-size: 20px;}

   --
   You can mix though ..

   <h3>This will be 10px tall</h3>
   <h3 class="bigger">and this would be 20px</h3>

   or you could have

   .red {color:#ff0000;}
   .green {color:#00ff00;}
   .blue {color:#0000ff;}
   and then do
   <p class="red"> Have some red <p class="blue"> and some blue etc...

   Some formatting above is screwed - and I'm sure someone else will explain better :)

   That actually makes sense to me. Thanks. I owe you one. I always wondered about that.
