Emoji, Emoticons and Symbols
Once you have some experience using HTML in REDCap forms you'll soon realize that there's a wide range of characters and symbols that can be represented with HTML.
Here, for example is a survey question that uses enhanced radio buttons and checkboxes and also smiley face emoticons.
This technique uses symbols from the unicode character set, font sizing using em units and REDCap's enhanced radio button feature (survey settings).
Here's the html for the choices list in REDCap:
1, <span style="font-size:1.5em">😃</span> Happy
2, <span style="font-size:1.5em">😐</span> OK
3, <span style="font-size:1.5em">😡</span> Sad
The <span> tag allows us to increase the font size. 1.5 em instructs the browser to show the text within the span 1.5 times larger than the current default size.
