I was humiliated because I participated in the development of a site to calculate the time in LoL and I dared to do it in pure html/css....

Let me explain: since I was a teenager, I have loved creating sites around the League of Legends community and my portfolio is therefore full of similar projects. I live in a city that is not necessarily tech and so it was complicated for me to find a coding school but I ended up getting there and being accepted. From the 3rd day, my classmates questioned me and asked to see some of my projects. Proudly, I show them https://wastedtime.io which is a project in which I voluntarily participated by making html/css allowing them to recover the time spent on LoL. When suddenly one of them asks me the question “how did I do the front”. So I told him I did pure HTML/CSS. So he looked at me with a haughty look, making fun of me for not using React, the strangest thing was that the others were following me and looking at me like I was a dinosaur. What's wrong with people? I had already done this with PHP on the Internet and now in real life I also get mocked with HTML and CSS without using libraries. I learned my lesson with PHP, but now I have to face the same ridicule with pure HTML/css because I'm "not good enough with my time"? Aren't the reactions a little disproportionate? I mean, do I have a few more years left without being singled out and called a dinosaur like php coders or is it already over for those who do pure HTML/css ?

In your opinion, there are more lines of malicious or benevolent code on the internet in general? What percentage do you think would be? (This time - if we don't speak in-universe)
