Spec is not clear on how to handle this. Three variations exist:
```
$ echo '' | /home/user/commonmark.js/bin/commonmark
<p><img src="image.png" alt="text <textarea> text" /></p>
$ echo '' | /home/user/cmark/build/src/cmark
<p><img src="image.png" alt="text <textarea> text" /></p>
$ echo '' | /home/user/.local/bin/commonmark
<p><img src="image.png" alt="text text" /></p>
```
Prior to this commit:
- when HTML tags are enabled, tags were removed (as in Haskell version)
- when HTML tags are disabled, tags were escaped (as in C version)
After this commit:
- tags will be escaped (as in C version) regardless of HTML flag
+ render hardbreaks as newlines, same as cmark
In this change set I am changing the guidance in the README
and in comments to put the class on the correct tag: `<code>`, not `<pre>`.
If you put the `hljs` class on `<pre>`, syntax highlighting
does not use the correct padding.
You can see from the default CSS stylesheet in the highlight.js
repo that the `hljs` tag is expected to be on the `<code>` tag:
84719c17a5/src/styles/default.css (L17-L25)
All the official highlight.js examples have the `hljs` class on `<code>`:
