Always make a backup copy of your css before you make changes.
Okay… I can’t remember exactly where I got this. It’s from google and it worked for me. I’m using a child of the twenty ten theme. I’m going through my css and documenting the changes I’ve made. I’ll do better next time to make sure I credit the original poster. If you do know the original poster, please leave their url. I don’t know how to do all the ping back or rss stuff. Still learning.
Find the following line in the css. Make sure you’re using your child theme css.
/* =Header
-------------------------------------------------------------- */
Under this line of code add a couple line breaks and add the following code:
/* The main theme structure – reduce top margin to compensate for changes to Header*/
#wrapper {
margin-top: 5px;
}
/* =Header – add clickable logo to title */
#site-title a {
padding: 10px 10px 80px 100px; /* allow space for image */
background: url(images/lukeup-logo-105×105-dark-blue-small-U.png) no-repeat;
}
#header {
padding: 0px 0 0 0;
}
#site-title {
float: left;
font-size: 45px;
line-height: 136px;
margin: 0 0 18px 0;
width: 700px;
}
You will have to remove the exsisting site-title. I had to experiment with the line height and ‘site-title a’ padding.
Good Luck.
