# What HTML Tags are Allowed by Quickbase?

Quickbase allows for customization of the platform with HTML and CSS within certain features. JavaScript is supported within [code pages](/v1/docs/create-code-pages). Content is also constrained by limits such as character count as defined in [limits in Quickbase](/v1/docs/limits-in-quickbase). *Quickbase may also block identified security vulnerabilities proactively and without notice to protect the security of the platform and our customers.*

HTML and CSS is generally accepted within a few areas:

| **Area** | **Supported** | **Unsupported** |
| --- | --- | --- |
| Code pages | - Browser-supported HTML - Browser-supported CSS - Browser-supported JavaScript |  |
| Rich text fields, data entered by users (*unsupported content may be accepted at entry but will not render for users*) | - "Display" HTML and CSS (to format and decorate text) as supported by the rendering browser and included in the identified list below | - HTML or CSS that allows for interactivity such as, but not limited to: - Script tags - Event handlers - iFrames - Ajax calls - All JavaScript - Style tags |
| Text elements on a form, when `HTML` is turned on | - bold - italics - paragraph - span - a - img - table - table row - table cell - table heading cell |  |
| Formula rich text fields, created by builders (*unsupported content may be blocked during creation or runtime*) | - "Display" HTML and CSS (to format and decorate text) as supported by the rendering browser | - HTML or CSS that allows for interactivity such as, but not limited to: - Script tags - Event handlers - iFrames - Ajax calls - All JavaScript - Style tags |
| Realm branding - Header - Footer - Sign-in page | - Basic HTML used for display purposes | - Script, object, embed, frameset, iframe, applet, html, body tags - JavaScript - CSS - Style tags |

## Tips and tricks

## Inliner

Certain properties are not allowed to exist separately in a tag such as `style`, for security reasons. These properties may be included *inline* with HTML tags though. Tools such as the [Mailchimp Inliner](https://templates.mailchimp.com/resources/inline-css/) can help with this process.

## Quotes in a formula field

Within a formula field, quote marks `"` are used to define a text literal. Within a rich text field, the HTML is considered part of the text and must be defined with quotes. This will require quote marks to be escaped, as shown in our help article about [color-coding fields](/v1/docs/color-coding-fields).

## Sample HTML tags for use in supported areas
