How to fix errors in HTML code?

Question

Images

Hello!
Crazy help needed!
I am a shoemaker without boots, and in short, a marketer without knowledge of HTML.
Here is the link to the code:
https://drive.google.com/file/d/1P4YeQ-tvKsGIu2-b_...
Required:
Fix bugs to make the code look good in major browsers.
Replace pictures - word cards should match the words, pictures for other blocks should be similar to the sites where the links lead (make the image resolution match the images in the code).
For the spots in the dictionary, put a blue background, like other blue elements.
I ask algorithmically to explain to me how to do it.

Answer 1

Algorithmically, everything is quite simple:
that crap needs to be changed and this one needs to be corrected.
Was extremely happy to help.
