I'm completely new to the world of Web design.

When browsing websites, I often notice a certain effect where there's a mask over images with text overlaid on top. How can I achieve this effect without directly editing the image?
Currently, I'm using a Bootstrap Jumbotron for the header section of my website, with the container-fluid property and a height set at 100vh. I've set an image as the background of the jumbotron, a common practice found in many websites like https://i.sstatic.net/sShTe.png.
My question is, how can I add a black tint overlay to the background image so that white text can be easily read on top of it?
P.S. I have very limited experience with CSS, and just learned about these masking and overlay techniques today.
