How can I modify the page title font and width in the Dawn theme?

On my website, https://www.fleshandbloodcards.com in the header I have a link “Expansions” to the expansions page.

On that page I have the page title (no body text) then a multi column section.

I want to remove the title from the multi column and change the page title width and font so it looks like the multi column text shown below.

How would I go about doing this please? In fact, on all my pages I have the page title shown in H1 (I guess) int he middle or to the left of the page in this HUGE font. I would rather have a small font, in bold type, across the full width of the page. How can I change this in each page please?

I’m almost there!

I worked out how to do this. I just removed the multi column title/heading then changed the custom css for the page section to include:
h1 {
font-size: 32px;
}

Althoguh I haven’t quite worked out how to make the title run the full width of the page and line up with the left edge of the section following it, yet.
