Hi there @Tristyn, and welcome to the community.
Your HTML looks really good — well done on some great work. I noticed a couple of small things you could improve on, but nothing major:
- The date of the letter —
20 January 2016
— isn’t part of the address, so it’d be better to put this in it’s own a separate block level element, out side the <address>
element:
<p class="sender-column"><time datetime="2016-01-20">20 January 2016</time></p>
- There are some odd character encodings going on in this bit:
Measuring the effect on performance of funk bassplayers at temperatures exceeding 30°C (86°F), when the audience size exponentially increases (effect of 3 × 10<sup>3</sup> increasing to 3 × 10<sup>4</sup>.)
Not sure where those came from
