I think you should be looking at CSS to control the presentation rather than HTML.

Go to https://www.w3schools.com/ to learn about HTML, XHTML, and CSS.

Go to https://www.w3schools.com/site/site_validate.asp and validate the segments of your website, i.e. https://gangleri.nl/bookreviews/

You’ll see this one failed the XHTML validation with 49 error.

You’ve got a number of errors in your XHTML. Go to https://validator.w3.org/ and run it with your URL. You’ll see 78 errors. Many of the errors are minor. Others are serious.

You’ve got something buggered up in your XHTML. Go to https://validator.w3.org/ and run it with your URL. You’ll see 31 errors. Most likely, if you fix one, most or all of the others will go away. Make sure for every start <div>, you have a end </div>.
