Below is a beautiful pop-up code in which each headline is inside a circle with a colored radius, and when we go over each one, each one has a slightly larger margin around it in hover mode, in other words, the radius of the colored circle around each text. Increases and by clicking on each text title, the surrounding circular radius increases to the extent that it takes up the entire page and the full text is displayed.
