Re: How to make bigger font for the default text
The theme sets font sizes specifically for many items so there is no way to increase the size of all text in one step. If you want pretty much every instance of, say, "FONT-SIZE: 9px" to be changed to "FONT-SIZE: 11px", then you could do a search-and-replace on twist.css with a text editor.
If you need to target a specific instance of text, then maybe you can determine what CSS selector is involved by checking the page source and seeing what divs and so on the text is within.
