Font size

you can try adding a font-size property to the body (or whatever element you want to change) selector:

body {
    font-size: 12px;
}

this line at the end of style.css did it for me:

body, h1, h2, h3, h4, h5, h6, ul, ul li, a, p
{
font-size:24px!important;
}

every single letter the same size –flat-liner-font-size– lol ??

but what is the point of that?

Hi, I am trying very hard to increase my Paragraph font size also. My style.css for my theme is very limited so I tried to add:

body, p {
    font-size:12px!important;
}

nothing changed, so also tried:

body, p {
    font-size:20px!important;
}

My style.css sheet says:
