Help with new site

Hi World,

My name is Hesten, and I am working on a fairly new site called Hesten's Learning.

I started working on the site in an effort to change the way that online E-learning platforms for administering their content to be better suited for those with learning differences. I am focusing on an A11y based approach for better usability (TTS, Dark mode, Font's ECT..), and I am running into some issues with making the site. I currently have a very crude starter (can be accessed here: Hestena62.com), and am looking for some help from someone that is a little more experienced than I am?

I realy dont know what I am doing, I just have the vision, and am using examples from online and Gemini to help. I had started out using HTML, but found that to muc to standardize as I changed the layout, and then went to a PHP approtch for its better usability and logics for the lessens and such.

I cam be reached VIA email at: [e-mail], or text/call at: 802-451-0781. The number is a google voice number.

Thank you all for your help.
