# Text formats

Some notes on text formats:

* The filters in the text format setting are applied sequentially, with the output of each filter being passed onto the next filter.
* Text formats should be assigned by role. Anonymous users should only have access to plain text input format, whereas trusted users can have access to _Rich text_ privileges so they can add links, images, and so on.
* The HTML filter only allows the following tags by default:

\<a href hreflang> \<em> \<strong> \<cite> \<blockquote cite> \<code> \<ul type> \<ol start type> \<li> \<dl> \<dt> \<dd> \<h2 id> \<h3 id> \<h4 id> \<h5 id> \<h6 id> \<img src alt data-entity-type data-entity-uuid> \<u> \<s> \<sup> \<sub> \<table> \<caption> \<tbody> \<thead> \<tfoot> \<th> \<td> \<tr> \<p> \<drupal-entity data-entity-type data-entity-uuid data-entity-embed-display data-entity-embed-display-settings data-align data-caption data-embed-button>

* The site administrator can add or remove HTML tags from this list in the **Filter settings** section from **Configuration** → **Content authoring** → **Text formats and editors** → **Rich text**.
