I am new to SharePoint. I want to add different tiles (Small Size) on home page and then I want to link those tiles to different site pages. I don't know the procedure. Please help me to solve this problem.
Have a look at the quick links web-part in a modern site. You can create links to pages with each link that you add and hey can have icons and borders too. You can add your own small images or use the image webpart to link to pages.
