Beforehand I simply tried styling it in my style.css file, like <code>textarea {font-size: 30px;}</code></p> <p>I'm also using a bootstrap theme that replaces the header tags with something else so I won't have any luck changing the size with the to tags.</p> <p>Note that changing the font size in the CSS stylesheet will change it everywhere but the textarea it looks like.
