Seems they have messed up the pages. How can I put the heading "overview" into a blue bar now? See Semeru page.

Fixed the blue header for you.

So you know how, see it done 25 seconds into this video:

Thank you, Matt!

Hi Matt,

May I bother you again? How can I change the letters to normal size?

Thanks!

Looks like you're using "Tertiary Header" tags in the text. No need to do that unless you want the font to appear larger and bolder, like it did in most of the page before I edited it. The font size is normal now
