Are the links to internal or external pages? Because you can’t control the font size of external pages (Well, you can in each individual browser that visits the page but that is only if the user of the browser does so, that is, change the default font size in the browser)
I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.
You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.
See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (’).
