Seeking Constructive Criticism on My HTML/CSS/JS Personal Website

If you're interested in data binding, you might want to explore using Vue. It's totally fine to stick with vanilla JavaScript for learning, but using Vue can simplify your custom JS. Just remember, organizing your CSS into separate files can help with performance through page size and caching. Nice to see you're incorporating CSS grid!

I think you could benefit from asking DeepSeek to optimize your code. I’ve made several sites with their help and they can be really resourceful.

It's awesome that you're using plain HTML, CSS, and JS—great for learning! One area to improve is your form elements; they lack labels and solely rely on placeholders, which isn't user-friendly. Adding labels can really enhance usability.

One of the first things I'd recommend is focusing on code indentation for better readability. Using proper indentation helps your brain parse the code structure quickly and shows the hierarchy of elements. Also, I noticed some optimization issues with images; you're loading larger images than needed. Adding alt tags to images and names to buttons is crucial for accessibility too. Your robots.txt also seems to have some errors.

You should consider combining your CSS files into one that you can link to from each HTML page instead of repeating styles. The same goes for your JavaScript, if you have multiple files. Also, running your JavaScript through a Beautifier tool can help improve readability. These are just suggestions for now, but it's a great start! Keep it up!
