====Displaying tags====

{{tag|tags|o}} do not display; they are just markup. If you want them to, insert {{tag|nowiki|s}} after an {{code|<}} opening angle bracket; it goes only in the very front. Opening tags and closing tags must be treated separately.

<pre>
<span style=color:blue> Blue </span>
<<nowiki />span style=color:blue> Blue <<nowiki />/span>
<section end=la<nowiki />bel /> </pre>

<poem>
:<span style=color:blue> Blue </span>
:<<nowiki />span style=color:blue> Blue <<nowiki />/span>
:<section end=la<nowiki />bel /> {{cross}}
</poem>

Use template {{tl|tag}} instead of nowiki tags to display parser tags:

'''Character entities''', nowiki cannot escape.  
To escape HTML or special character entities, replace <code>&</code> with <code>&amp;amp;</code>.
For example, <code>&amp;amp;lt;</code> &rarr; <code>&amp;lt;</code>

To '''display a nowiki tag''', you can (1) use {{tl|tag}}, (2) replace the < left angle bracket with its HTML character entity, or (3) nest nowiki tags in each other:

<pre>
{{ tag | nowiki }}
<code>&amp;lt; nowiki>...&amp;lt;/ nowiki ></code>
<code><<nowiki />nowiki>...<<nowiki />/ nowiki ></code></pre>

<poem>
:{{ tag | nowiki }}
:<code>&lt; nowiki>...&lt;/ nowiki ></code>
:<code><<nowiki /> nowiki>...<<nowiki />/ nowiki ></code>
</poem>

<pre>
{{ tag | nowiki | s }}
<code>&amp;lt; nowiki /></code>
<code>&lt;&lt;nowiki /> nowiki /></code>
<code>&lt;nowiki>&lt; nowiki />&lt;/nowiki></code></pre>

<poem>
:{{ tag | nowiki | s }}
:<code>&lt; nowiki /></code>
:<code><<nowiki /> nowiki /></code>
:<code><nowiki>< nowiki /></nowiki></code>
</poem>

Nowiki tags do not otherwise nest, so it is the second and fourth that displays:

<pre>
1&lt;nowiki>2&lt;nowiki>3</nowiki>4</nowiki>
&lt;nowiki>{{!}}&lt;nowiki></nowiki>{{!}}</nowiki>
</pre>

<poem>
:1<nowiki>2<nowiki>3</nowiki>4</nowiki> {{spaces|5}} ''{{small|second and fourth}}'' 
:<nowiki>{{!}}<nowiki></nowiki>{{!}}</nowiki>
</poem>

These simply scan from left to right.
The paired tags cannot overlap, because the very first pair-match nullifies any intervening tags inside. Unbalanced tags always display.

Nowiki tags do not display table markup, use {{tag|pre}}.
