font / paragraph style limitations

Hello again from a first-time Squarespace user.

As far as I can tell, there are really only TWO font styles that are available on any given website — Headings and Paragraph. The variations of these (Paragraph Small, Paragraph Medium, etc) are really only different sizes of the Main Style for Paragraph. This seems very limiting. I understand wanting to help the user keep things from looking chaotic, but I was hoping that each Style (small, medium, large, etc) would allow for italic, bold, different line spacing (very important!!) for each style. So, I was hoping for 4 paragraph style sheets, and 4 Headings style sheets. Line spacing for a title under someones name needs to be different than line spacing for a main paragraph of body copy.

Any help would be greatly appreciated — thanks!

1.  Typing the text you will see the in this black text box. And the possibility to make the chosen text bold or italic. Italic is shown with this “/“ slash sign.

2.  In  the style panel you can choose three headings h1 h2 h3 and normal. This is the same with all templates. So you will have 4 different possibilities.
the font it self if serif or what ever you want - can be chosen in the style panel. than you can define whether you want capitalized or normal you can give each of them a different size. Same with line hight, and character distance.
