How to display code in code

Question

So I created a h1 tag and created another h1 tag in it. But it doesn't display it. I want to display an example code in output. Can I plz have the most simple code example about that? Thanks

Answer 1

You can do this by replacing < with &lt and > with &gt
So if you wanted to put h1 in a h1 tag just put <h1>&lth1&gt&lt/h1&gt</h1>
