I recently started my first wordpress task and it's about creating a custom page within a website. Now I know my PHP, CSS and HTML but while I am being used to working with angular etc. this is a new step for me.
I read about themes, plugins and templates but I do like to get some additional info from you all! Here are my questions:
What should I use to create a page (with logic in it)? a theme, template or plugin?
Is there a way to build up a page dynamically in wordpress? Like for example by a tag in the URL the pages show different images with the same tag?
The page im working with already has a standard theme so my new page should take over that style.
Thanks in advance!
