i have a concept to place each image in an individual triangle div

struggling to find a way to implement this idea

reaching out for assistance on how it can be achieved.

please refrain from using the map tag, looking for independent areas

Answer №1

In order to click only within a triangular area of a div, as opposed to the entire square size, you will need to add an onclick function with a check for mouse coordinates. For example, if the triangle is cutting a square div diagonally, this is how you can achieve it:

https://jsfiddle.net/3tdysenL/8/

This particular demo works on the upper square for the top-right triangle. If you require more complex coordinates, you may need to revisit high school formulas for Cartesian coordinates to determine if a point lies inside a triangle.

I hope you find this information helpful!
