How do I change tab colors on my blog?

in your theme’s style.css file you need to find this line of code:

#header li.current_page_item a

and change the background color attribute to whatever colour you’d like. at the moment it’s set to #fff which is plain white. this line of css specifies the tab that corresponds to the page your on (php shenanigans will take care of assigning it to the relevant tab)

hope this works.

In your style.css look for this code around line 146

#header li a {
-moz-border-bottom-colors: none;
-moz-border-image: none;
-moz-border-left-colors: none;
-moz-border-right-colors: none;
-moz-border-top-colors: none;
background: none repeat scroll 0 0 #FFFFFF;
border-color: #F7951E #F7951E -moz-use-text-color;
border-style: solid solid none;
border-width: 1px 1px medium;
color: #84755C;
display: block;
float: left;
margin-right: 2px;
padding: 8px 14px;
text-decoration: none;

}
Change #FFFFFF in this line to background you want
background: none repeat scroll 0 0 #FFFFFF;

Change this line #84755C to the font color you want
color: #84755C;

That worked but only for one of the tabs

How do I change it for the other two?

You mean the code I posted only changed one tab it should change all and then you want to change hover tab its code just below that one one hover and one for current page.

Actually it worked! Do you know how to change the font inside the tab to make it bigger and bold?

add
font-weight: bold;
font-size: 15px;

add this two line before
} in the code I posted above #header li a

it worked!!!!! THANK YOU SOOOOOOOO MUCH

You are welcome
