I have been creating posters which have similar contents for the last few months and this got me wondering if it's doable to program a tool which helps me just add the smallest details and reduce my workload.

Now my question is what programming language would work best for this kind of project? I did think browser-based so HTML, CSS, etc or a software-ish approach like maybe Python? What are your thoughts? I will be linking some of them.

As you can see very minor changes. For the posters mostly just the title, prizes, some minor details and for the podium it's the title, date, then the player and the parts used. Any help would be great, thanks a lot! <3
