How to change font size in a textbox in html

Question

How can I change the font size of text inside the textbox in html.

Answer 1

To actually do it in HTML with inline CSS (not with an external CSS style sheet)

A lot of people would consider putting the style right into the html like this to be poor form. However, I frequently make extreeemly simple web pages for my own use that don't even have a or tag, and such is appropriate there.
