Help with development page or dataset page

Hello … good night,

I’m developing a project where I need to collect some XML data and display on the screen, I’m currently doing this by creating an html page with php on an Apache server and put it in Xibo as a webpage. Create all transitions in html and css as a normal web page,
I wonder if this is the right way to do this in Xibo? Because I know I can use the dataset, but can customize the page in Xibo own?

I’m having some performance issues where the internet is bad. I’ve never worked this way with the Xibo, so I’m sorry I’m asking something very basic.
