rwalters, you can accomplish this using CSS without a revision to Lectora (although it’ll be a welcome addition).
In the attached example, I set up a CSS rule that will be applied to any multiple choice text block that has been assigned a class of “custom” – no quotes.
This will work with any multiple choice question. The awt file is included in the zip file. load it up and play around with the answer text blocks by assigining or unassigning them a class of “custom” – no quotes. You will see that those that are assigned that class will be resized to 8pts (as determined by the added css.)
To use this, copy the css that I added (or just grab the fontSize.css file), add it to your project via HTML Extension – Cascading Style Sheet. You can change the font-size to whatever you wish. You can also style just about any other font attribute by adding them to the rule.
If you or anyone else would like to implement this and need assistance, or if you just want to understand more about how this works, shoot me a message.
