Currently we allow the following HTML tags in comments.
Single tags
These tags can be used alone and don't need an ending tag.
<br>
Defines a single line break
Matching tags
These require an ending tag, e.g., <i>italic text</i>
<a href="https://disqus.com">
Defines an anchor link<strong>
or<b>
Defines bold text<blockquote>
Defines a long quotation<em>
or<i>
Defines italic text<strike>
or<s>
Defines strikethrough text<p>
Defines a paragraph<span>
Defines a section in a document<caption>
Defines a table caption<cite>
Defines a citation
Text Formatting
Rather than having to manually add markdown syntax to your comments to format text, you can now use text formatting shortcuts within the comment box.
To use this, you can click on a formatting option, and type the text you wish to be formatted inside the tags that are added.
Alternatively, you can highlight the word that you want to format, and then select the desired formatting.
Here are the current supported formats:
Bold
Italics
Underline
Strikethrough
Hyperlink
Code
Blockquote
Syntax Highlighting
Disqus supports automatic syntax highlighting in a number of languages. To use this feature, place your code inside <pre><code>
tags. For example:
<pre>
<code>
var foo = 'bar';
alert('foo');
</code>
</pre>
By default, Disqus will try to automatically detect the language. It's pretty good at this, but you can give it a hand by doing the following:
<pre>
<code class="javascript">
var foo = 'bar';
alert('foo');
</code>
</pre>
Supported languages
Bash
Diff
JSON
Perl
C#
HTML/XML (Note: You must first HTML-encode these tags to display them)
Java
Python
C++
HTTP
JavaScript
Ruby
CSS
Ini
PHP
SQL
Note: Syntax highlighting will automatically close tags. To place a tag in code without closing, use < and > instead of < and >, to override this behavior.
Spoiler tag
Disqus supports the ability to hide text in your comment using spoiler tags.
<spoiler>Hello, world</spoiler>
Hides text until hovered over or clicked on
