Help with optimizing HTML

Hi everyone,

I have just published my portfolio using a bootstrap theme with custom code HTML templates online. All the pages are okay apart from the "About me" page. The layout and images are all over the place and it looks a hot mess. Can anybody help me with any suggestions on how to fix this?

If there an optimization code or something I'm meant to include in my CSS please let me know.

Start with delete all your custom code. You can't copy a wordpress page and add it as custom code.

Your page is loaded over HTTPS , but requested insecure elements, they are blocked. All JS, CSS, PHP and image files you request from wordpress are refused

There is not one right on that page lol

Ok thanks!
