Code Block affecting text styles that come after

Hi I've added a small image to my website using a code block that is pulling an uploaded image into the code block.

The image is a graphic that reads, "MOST POPULAR".

The placement is fine, but everything after the code block, in that section, specifically all the text, now is acting like a used link/button. It has gone gray and blinks on roll over.

Here is the site: https://workheights.com/#members

Here is the code:

<a style="display: block;text-align: center;">
<img src="https://static1.squarespace.com/static/55099790e4b0bcc6146f3c96/t/5df401479726b96c27144a52/1576272199597/MostPopular.png" width="200" height="95">

It seems this inserted code, is not properly closing, so that it affect the rest of the section.

I'm not a code expert, but this seems like it should be a simple fix.

Any ideas?

@FromBrooklynwithlove It should be
