How to customize HTML code to quickly modify content

I created a website where I want to constantly modify data. This means adding more text, adding files, etc. I want to know how to do this. I can do this using cms but I don't know how to integrate it with my website. Here is an example of my website page.

I often need to add new dates with new files with the same style. [1]: https://i.stack.imgur.com/Vs9tj.png

If you are constantly adding new content, I recommend trying Javascript ES6 or possibly React.

Using Javascript DOM will be the best method. Definitely consider using document.getElementById().innerHTML
