CSS - possible to have two different font sizes per line within the description in a Simple List?

Attached is Description text with a line break. I would like to know if it's possible to customize a different font size per line, or any kind of differentiator.

Hi Monica, yes this is possible - please share your website so we can check

You can consider using Markdown Block & with this syntax

<p>enter text 1</p>
<p style="font-size:20px;">enter text 2</p>

If you want to use paragraph 1, change p to 

<p class="sqsrte-large">enter text 1</p>

with paragraph 2, just use <p> is enought

with paragraph 3, use this

<p class="sqsrte-small">enter text 1</p>

if you want to use heading, just use # (h1), ## (h2), ### (h3)...

## enter heading 2
