Resize the title

Use CSS. The title might have a class=”entry-header” or something similar, it depends on the theme. You can examine it using firebug or the Safari Web Inspector or IE Developer Tools to find out how it is styled at present.

In Twenty Eleven, the class for the title is “entry-title” and it’s style is set to 26px around line 730 of style.css. You can either modify the style in the theme or set up a child theme that consists or a style.css file that will override the one in the parent theme.

set up a child theme that consists or a style.css file that will override the one in the parent theme.

You really, Really, REALLY want to follow that last part of the advice. Make a child theme now and save yourself pain an suffering later when the theme gets updated.

It’s easy to do and all you are modifying is the CSS.

I’m not so good in CSS, is it hard to make a child theme?

Jan’s link shows how to set up a child theme. It’s easy and CSS is worth learning. All you need in the css is
.entry-title {font-size:20px;}
to make it 20 pixels high.

Thanks for help!
