font size of page title is differnet to other pages

Why with WordPress do they let you do a load of work using a parent twenty eleven theme only for you to find out thru the forums that if you are tweaking your css that it may’ve been better to have created a child theme first? That’s not pointed out to newbies anywhere in the getting started stuff… or home dash page, particularly as you’ll lose any changes if an update comes along (security or otherwise) – at least that’s what I am reading here.

I have wasted so much time sussing this issue just trying to get this site of mine configured with a child theme but luckily found a good vid on youtube by kimmimebaby that explained it in a few minutes flat.

The problem is that I have added the css changes now to my new child css sheet in it’s twentyeleven-child folder in wp contents and yet 2 of the pages (out of a total of 12) are still showing the orig css title font of I think it’s 36? although my child css instructs them to show at 24px which works for the other pages – howcome?

Here is the child css:

/*

Theme Name: Twenty Eleven Child
Theme URI: http://www.fatigue-symptoms.com
Author: Ian
Description: The new child theme of Twenty Eleven
Version: 1.0
Template: twentyeleven

*/
@import url(“../twentyeleven/style.css”);
.entry-title {
clear: both;
color: #222;
font-size: 24px;
font-weight: bold;
line-height: 1.5em;
padding-bottom: .3em;
padding-top: 15px;
}

Any ideas anyone ?

Thanks a lot for any insight,
