I am somewhat new to web development and wordpress. I am having problems being able to edit content such as sidebars on my page. Widgets are enabled, but there are not any widgets that hold the content that I want to change. I want to change a link and add a link on the right hand side of my homepage. I am more familiar with html and css. I realize (now) that my page is run with php and there will not be an index.html file. I am running the Furniture Store theme, with Furniture Store Light child theme. I have gone to appearance -> editor. TheFurnitureStoreLight only contains css style files and a functions.php. The parent TheFurnitureStore theme holds a ton of php files, but I don't know where to look.
Question #1: (themes)
Is the child theme the main theme that I need to be working with?
Question #2: (editing)
I have been told that php just references infomation, unlike html. Where can I find the file that holds information such as links that i want to change.
Question #3: (shortcut)
I tried looking at the source code to find where data is held. I realize that is not useful when using php. Is there any easy way to be able to find what php file needs to be edited to change specific parts of a webpage?
I hope this makes sense and that I can get some help. thanks in advance!
