1. Go into Blogger, edit the template for your blog
2. Click on customize
3. Click on advanced
2. Click on customize
4. Scroll all the way down to "Add CSS." You might have to click and use the down arrow.
5. Add something like what you see below.
6. I added the following:
div, post, span
{
font: 16px arial,sans-serif !important;line-height: 150% !important;
}
Explanation:
- font size is set to 16px high, a fairly large font.
- font is set to arial
- line spacing is set to 150% or a space and a half to make it easy to read
- "!important" says "override any other individual setting and use this"
