I like to use the Atahualpa theme (it's really great), but I can't get my finger on the next thing:

at http://overlegbk.nl/wordpress/ you can see the blog title 'Overleg Beeldende Kunsten'

All pages look equal according to the position of the blog title (homepage, http://overlegbk.nl/wordpress/?page_id=2 and http://overlegbk.nl/wordpress/?page_id=7), but the page I am using for showing my blogposts (http://overlegbk.nl/wordpress/?page_id=12) looks different.

There the blogtitle (and the page as a whole) jumps up.

my Atahualpa configuration:
- Style & configure LAYOUT>Layout Container Style>margin-top: 40px;
- Style & edit HEADER AREA>Blog Title>margin-bottom: 10px;

Can somebody help me out?

Many thanks in advance

Read the instructions about the Layout Container Style box regarding margins.

Ok,

I read the instructions of NOT using margin-top in the layout container style box.

So I used padding on the body (see menu tab "Body, Text & Links") as was proposed, but with no effort:
the blog post page is still jumping up.

I really don't know what to do.

The difference is because on the blog pagem the title is an H1 and on the other pages it is an H2 and in the CSS inserts there is code for H1 and H2 that is different.

???

I am talking about the blog title (so it's in the header of the HTML)

Is a blog page using other CSS than normal page for the blog title?

it has to do with SEO. On a blog page the blog title is an H1 and each of the post titles are H2's. This is because there is should only be one H1 on a page.

On a single post page the post title should have the highest precedence therefore it is made in H1 and the page title becomes a H2.

If you look in the CSS Inserts, you will see some CSS for 'H1' and difference css for 'H2' this is what is causing the change.

Thank you juggledad.

Now I made no distinction between H1 and H2 (I editted the CSS rule).
