How to add text title to a video track and use animations?

tbkr Posts: 16 Just Starting Out

Hi, I can't figure out about adding a title to a video:

When I usually create that with a composite shot, it has it's own background, so when I add it to the video track it covers the entire video screen. What is the correct way to add text with the title background like a box (above picture) to a video track, not making the video screen disappear? I want it to be something like this:

See? Isn't covering the entire video...

Next, I want those text and boxes to appear and disappear in an animation, like appearing in a fade motion and disappearing likewise.

Is there a way to do all of these?
