My Custom Title
My body text here, is a separate text box from the one above, which was used for the title.
In the text box above, and in this one, I deleted the block title when creating the content block.
For the title text above, I highlighted the text in the text editor, chose a Font Family, and increased the size of the font. (You can also try changing the text from the Paragraph setting to one of the Header settings. This works better with some fonts than with others.)
I also changed the colour of the font using the 'A' icon in the text editor's toolbar.
You can also try changing the theme of your page (at the bottom of the content toolbar on the left) to achieve slightly different effects with the header text, and background colours in the page.
