What Blogger shows is HTML; you can use the <pre>
and <code>
tags as you would in normal HTML.
It's been a while since I last worked with Blogger, but IIRC it has an editor that lets you use HTML directly. Your <div class="yourClassName">
should work if you put it there, if yourClassName
has been defined properly. Which, in the case of computer programming code, usually assumes a monospaced font, among other preferences.
There are a number of resources that can help you format; I found this one that uses only <pre>
and <code>
to get your code in code formatting.
There is also this old, off-topic question on Stack Overflow that recommends various online resources. Since it's old, you'll have to experiment a little to see what still works.
