In this site PhotographWorks, the font size for the anchor text is bigger than font size for the body text.
The difference in font size between the anchor text and the body text has been bugging me.
I don’t know how the font sizes came to be different and I can’t see that I made any changes in global styles or anywhere else.
Look at this screen grab, and you can see that the font size for the anchor text Ghost Notes is bigger compared to the body text.

It’s been bugging me but I didn’t get around to doing anything about it until today.
Enter Claude
Today I happened upon an email from WP.com that said that the Claude LLM could link to WP.com.
So rather than ask the LLM in the WP admin as I usually would, I asked Claude how to make the anchor text font the same size as the body text.
It came up with a couple of suggestions, one of which was to add some CSS.
Classic vs Block Themes
I am using the Twenty Twenty-Five WordPress theme, which is a Block theme.
You will see these themes referred to as full site editing (FSE) themes.
What makes Block themes different from classic themes is that Classic. themes are built on PHP.
Block themes are built from HTML templates. And bingo – those templates are made of blocks.
This automatically enables the FSE site editor.
So for most purposes we can say that Block themes are FSE themes.
If you didn’t understand all that, neither do I completely.
The Customizer
The thing is that with Classic themes you can usually use the Customizer and tweak the theme and add CSS.
You might think therefore that with an FSE theme that you can’t get to the Customizer to add CSS, but you can if you know where to go.
Instead of going to Appearance / Editor in WP Admin, instead go to yourdomain DOT com/wp-admin/customize.php and you will see it says:
Hurray! Your theme supports site editing with blocks. Use Site Editor
Ignore Use Site Editor, and below that you will see that it says
Customizing < Additional CSS
Add your own CSS code here to customize the appearance and layout of your site.
And that’s where you add your CSS.
Here is the CSS that I added:
.entry-content p a { font-size: 1em;}
And here is a screenshot of the section of the post as it looks now with the anchor text and the body text the same size.
