The Rich Text Editor available in the Field Label and other locations in REDCap provides point and click menu functionality to change the formatting of fields and surveys.  The variety of fonts, sizes, colors and other functionality, however, are limited.

REDCap allows the use of some HTML and CSS in the Field Labels, Field Notes, Multiple Choice coding, and other locations.  HTML and CSS allows access to a wide variety of functionality to change the look and feel of surveys.  For example, here is a full list of named colors you can access!

Some basic information about HTML:

• HTML works by enclosing the text you want to format with HTML "tags".
• The tags can be included in your Section, Descriptive, Question and/or Answer texts.
• A tag is a type of instruction or command that will change the appearance of text as well as perform other functions on your REDCap forms because they are web pages.
• The tags are enclosed with greater and less than < brackets > and may be written in capital and lower case letters.
• You need to both open a tag and close it.
• You close it with the same tag but add a /

Example < center > centering text < /center >. *Do not leave spaces in tags when using the actual tag - see below for examples.

You can style your fonts in three basic ways:

Bold face font, Italics font, and bold&italics font together.

When you use the HTML code, <strong>Insert text here.</strong> , this will be produced.

Font Colors and Sizes with HTML

Another couple of different simple formatting options you can do in REDCap surveys or forms is having different font colors and font sizes.

...

All you have to do is use/copy these HTML Codes:

<font color="purple">This color will be purple.</font>
<font color="green">This color will be green.</font>
<font color="blue">This color will be blue.</font>

...

When you use the HTML code <font color="any color">Insert text here.</font>, you can get any color you want with the font.  Here is a full list of named colors.

<font color="red">This color will be red.</font> 
<font color="purple">This color will be purple.</font>
<font color="green">This color will be green.</font>
<font color="blue">This color will be blue.</font>

Font Sizes

For different font sizes, use this HTML code: 

<div style="font-size: 10pt">This is how you change the size of the font.</div>
<div style="font-size: 14pt">This is how you change the size of the font.</div>
<div style="font-size: 20pt">This is how you change the size of the font.</div>
<div style="font-size: 22pt">This is how you change the size of the font.</div>

<p style="color:red; font-size:75%;">small and red</p> 

<p style="color:green; font-weight:bold; font-size:150%;">bold, large and green</p>

Background Class Colors with CSS

REDCap's css includes some familiar background-colored warning boxes. Here is an example where a descriptive text question is used as a warning when someone tries to collect another time point in a longitudinal study without checking the enrollment status of the participant first. The code presented below is placed in the Field Label column (column E) in your data dictionary, or the Field Label box in the Online Designer.

Image RemovedImage Added

The code looks like: (please note that the code should all be place as a single line)

<div class="red" style="text-align:center;">
<h3 style="text-align:center;">Participant is not ACTIVE</h3>
Please review participant status form before continuing.
</div>

Copy and paste single line of the code below directly in the Field Label cell or your Online Designer
<div class="red" style="text-align:center;"><h3 style="text-align:center;">Participant is not ACTIVE</h3>Please review participant status form before continuing.</div>

You can also use "yellow" and "green".
