I'm a newbie on WordPress.com. I'm using the MistyLook theme on my newly started blog. (domain: wordpress.justaddfather.com) I'm using a Typekit font in the text of the posts. The problem is that the font size of the post appears too small to read easily on the screen in my browser. I fiddled with the dashboard HTML code in the post to enlarge the font appearance, but the vertical line spacing needs to be increased as well so that the horizontal lines of post text don't get too mashed together. I also found instructions in a WordPress forum for manually controlling vertical line spacing using HTML code in the post, but this is now getting cumbersome -- I don't think I want to have to manually adjust the code for each paragraph in every post.
Here's my question: Can anyone tell me if I'll be able to control both the font size and vertical line height of my posts by editing the theme's CSS style sheet? I'm not asking how to do this. I just want to know if it can be done before I upgrade. (If the answer is yes, and you can point to any appropriate documentation, I'd be grateful.) Otherwise is it possible that I may need to move the blog to a hosted site using the WordPress.org software, so as to be able to edit the theme's HTML template file?
I apologize if this problem has been addressed in a forum before. I've been searching around and can't find the answer.
Any help appreciated. Many thanks for your time.
