Snap points are like magnets on a fridge. Just like magnets stick to the fridge, snap points make elements (like pictures, text boxes, or icons) stick together on a web page.
Think of a snap point like a little box with a magnet inside. When you move an element near the box, the magnet pulls the element in and makes it snap to the box. This is a way of lining up elements on a web page so that they look neat and organized.
Snap points are very useful because they help make sure that elements on a web page are aligned properly. It's like when you draw a picture and you use a ruler to make sure all the lines are straight. Snap points do the same thing, but on a web page.
When you move an element around on a web page, you might notice that it "jumps" or "snaps" into place when you move it close to another element. That's because you've hit a snap point.
So, snap points are just little boxes that help keep all the elements on a web page organized and aligned properly. They are like magnets that pull elements together to create a nice, clean look.
