You end resolution looks good. I am also newbie but I can give you some suggestions your HTML and CSS.

HTML

For better accessibility you can give more information in 'alt' attribute. Like:

<img src="./assets/images/illustration-article.svg" alt="illustration of HTML and CSS foundtains article" id="illustration">

CSS

I think you should use relative units instead of px. Because at some point it may be break your design especially font size can be accessibility issue for your design. For example you can use:

h2 {
    font-size: 1.5 rem;
    line-height: 150%;
    font-weight: bolder;
}
