Apologies if I have missed the answer to what would seem an embarrassingly simple question!

I have just added a Twitter timeline to the footer of my WordPress site, https://www.logicmatters.net, using the Twitter-provided html code

<a class="twitter-timeline" data-width="auto" data-height="300" data-chrome="nofooter noheader noborders transparent" href="https://twitter.com/PeterSmith?ref_src=XXXXXX">Tweets by PeterSmith</a> <script async src="https://platform.twitter.com/widgets.js" charset="utf-8" ></script>

As you will see the tweets are displayed with black font colour. Is it possible either to add to this html, or add a CSS snippet using the governing Astra theme’s CSS snippets panel, which will control at least the tweet’s font colour (both for the tweet text and the tweet header)?

Ideally I’d like to control the font selection too.
