Creating a box for content

Hello every one, I’m trying to create a box to show some things like a text and some icons to images and videos. I already can create the box for images and videos that will appear after but I dont have any idea how to create this box for text, i thought in GUI but I dont know if it can be done. If someone can give me a help me, I’ll be very grateful.

I just need help in the text box

In the OnGUI() function, you call a GUI.Label. That’s all there is to it really. Check the Unity user reference for details.
