how to ask multiple selected question radio button/checkbox

There should be three checkboxes/radiobuttons. When I click on one, the others should be grayed out. For example, when I click on someone, I have to make different selections. When I click on the other, different selections. How can I do that. For example, when I click on the first radio button. There should be a file upload button at the bottom. When you click on the second radio button, there should be text for writing. How can I do this with html css?
