A Blog With No Name

First off, if you really don't like it you can remove it, by adding to you css custom sheet (under your account, design, custom sheet) a simple line like this (as proposed by JavaWoman on the comments page)

#top-search {display:none}

But I don't have anything against the search as an idea. However I really don't like the green shiny button, that really doesn't fit in, especialy with the dark top bar. Based on some reaserach and partlly on the code from JavaWoman's css customizations, I have replaced it with a much nicer blackish button.
The idea is simple, you put a new background image on the element in question, and "move" the original content (the green button) out of the way, so that the background is shown. This is done by padding it to the right, and makeing the containing div to be of fixed size, and not to allow anything that overflows to be shown.
The code should be like this:

/* Google search form - inside #myo2 */
/* parts of this code are from JavaWoman */
#top-search
{
  display: block;
  overflow: hidden;
}
#top-search div
{
  width: 250px !important;
  overflow: hidden;                   /* prevent visibility of 'old' button */
}

#top-search #top-searchbox
{
  width: 195px !important;
}
#top-search #gsearch-submit
{
  margin-top: 3px;
  margin-left: -2px;               /* flush with text entry */
  padding-left: 65px;              /* 55 + 10 for dratted padding */
  height: 21px !important;         /* input=15+4, button=17, background-img=16 */
  z-index: 100;                    /* on top of "powered" image */
  background-image: url(http://files.myopera.com/Quinnuendo/images/search2black.gif);
  background-position: 0px 0px;
  background-repeat: no-repeat;
}

If you want to use another button (for intance one that you created) you need to change the url to the picture. If you have a bigger picture, than you can increase the height apropriatelly. If you need more width, you will need to reduce the width of the #top-searchbox, since that part makes sure that the old button gets "pushed out". You will probably need to increase the padding in the #gsearch-submit too.

Anyway feel free to use customize the code. Once more thanx to JavaWoman, whose already done code I used and hence didn't have to think of it myself. There are more things about css on that blog if you are interested.
