Welcome to the forums @pamela-sarnia. You page looks good. Some things to revisit;
The title element belongs in the head element, not in the body element. If you want to use it in codepen, anything you want to add to the <head> element click on the āSettingsā button, then HTML and add it into the āStuff for <head>ā box.
I donāt normally comment on someoneās style because it is what it is. This is something you should have a second look at;
on smaller screens the ālife infoā section starts falling out of itās container. Since you stack ālife infoā and ātribute infoā maybe move ālife infoā to the left more and make the container a little wider.
Thatās a lot of fonts in the font-family. You donāt link or import Roboto and itās never used. Better to just have one or two fonts with a generic fallback (serif or sans-serif).
Iāve deleted title in main and move it to head section in setting.
Wikipedia Page is working.
Iāve tried to fix the floating but the two columns looks too narrow in mobile view. So, I make two mobile responsive display, one for computer screen (columns width 55% and 35%) and another for mobile screen (both width 100%). But, it doesnāt work. In desktop view, it still choose the mobile view.
I also tried max-width so it will be two columns in desktop view and one column in mobile view. It works perfectly but the margin is too wide.
So for now, it displays one column though I also make it two columns for desktop screenā¦
