In this article I'm going to explain, in a few steps, how to put text over an image on hover.

STEP 1: the JSX

• import image
• give image some basic styling

Result:

STEP 2: the CSS - part 1

• set the image container's position to relative: this will allow us to set the image overlay's position to absolute so that it can cover the image container
• set the image's width to a 100% together with display: block to fill in its entire container

STEP 3: the CSS - part 2

• the first 4 lines make sure that the overlay covers the full container
• I've set the overlay background to black and gave it an opacity of 0 to hide it
• I've set a transition period to later make to overlay appear smoother instead of instant
• the flex properties and the color are meant for the text that will appear on hover

STEP 4: the CSS - part 3

• I've set the opacity to 1 to make the overlay appear
• I've chosen a solid color for the overlay
• finally I'm styling the overlay text

This was my very first and easy-to-follow article, hope it helps ;)
