How to set the image to hexagon in css

The operating environment of this tutorial: Windows7 system, HTML5&&CSS3 version, Dell G3 computer.

CSS3 to achieve hexagonal Div image display effect

1. Effect picture

##2. Principle explanation

The main knowledge points used for this effect:

1. transform: rotate(120deg); Image rotation

2. overflow: hidden; Beyond hiding

　3. visibility: hidden; is also hidden, similar to display:none;, but the difference is that although it is hidden, it will still occupy a position in the web page

We need to use 3 layers of p. Rotate to get this effect (note: the size of the 3 layers of p is the same). The outermost layer p (boxF) is rotated 120 degrees, the second layer (boxS) is rotated -60 degrees, and the third layer (boxT) is rotated another -60 degrees, which is just back to normal. Our image is placed in the p background of layer 3. Because there is nothing in the first two layers p, they are purely used to rotate to obtain a hexagon, so set visibility: hidden for the 1st and 2nd layers p; and the third layer p is for pictures and needs to be displayed, so set visibility: visible; (Note: If you do not set visibility: visible; on the third layer p, it will inherit the visibility: hidden; of the second layer p(boxS) by default). There will definitely be excess parts after rotation, so set overflow:hidden;

for all three ps. After rotation and hiding the excess parts, we can get the hexagon we want. Another thing to note is that the width-to-height ratio of p must meet 4:5, otherwise the result will not be a hexagon. In the effect picture above. We also placed a p (overlay) in the third layer (boxT). This p is used for masking. When the mouse moves over the 6-sided shape, there will be a masking effect. There is an a tag inside p(overlay), which is a number. Clicking the a tag will pop up the layer and display the large image (note: this js effect has not been written yet).
