如何在Jquery中仅更改Div标签的标题背景颜色

I have a div tag in my modal dialog built using JQuery like this: div id="dialogxxxx" title="xxxxx" . I want to just change the font and background color of the title alone, i.e. only the place where the title is displayed. Right now it has a default color and font. I want to change it to a specific color, but do not want to change the background color and font of the entire div, just the place where the title is displayed. Is there a way to do this? I tried adding style tag to the div, but that changes the background color of the entire div, not the title alone. I also tried doing div#title, that didnt help either.I have a div tag in my modal dialog built using
