Implementation method of diagonal overlay layout developed in PHP in WeChat mini program

As WeChat mini programs become more and more popular, more and more developers are getting involved in the development of WeChat mini programs. One of the most challenging development methods is the diagonal overlay layout in WeChat mini programs. This article will introduce the implementation method based on PHP and provide some reference for developers who want to develop diagonal overlay layout of WeChat mini programs.

1. Definition of diagonal overlay layout

Diagonal overlay layout refers to arranging multiple elements diagonally, and each element has a different width. The angle of diagonal arrangement is usually 45 degrees or 22.5 degrees.

2. Implementation method

To implement an oblique overlay layout, you need to use the rotation and translation operations of CSS3. Since the interface layout of the WeChat applet uses Flex layout, we need to implement it according to the characteristics of Flex layout.

The following is the specific implementation method:

1. First, we need to add a blank div element between each inclined block to open up the space between the inclined blocks. .
2. For each inclined block, we need to set a wrapper div element to set the position, rotation, translation and other attributes of the inclined block.
3. For each wrapper div element, set the following CSS properties:

display: flex;  /* 使用Flex布局 */

align-items: center;  /* 垂直居中 */

transform-origin: 100% 0;  /* 旋转、平移基于右上角 */

4. For each inclined block, set the following CSS properties:

width: xxxpx;  /* 设置宽度 */

background-color: #xxx;  /* 设置背景颜色 */

position: absolute;  /* 绝对定位 */

transform: skew(-45deg) rotate(-45deg) translateY(-xxxpx);  /* 旋转、平移 */

Among them, -45deg is the angle of the inclined block, and -45deg is the angle of rotation, which is used to ensure that the top of the inclined block faces upward. translateY is used to set the offset of the upper and lower positions of each inclined block.

5. Finally, set the following pseudo-elements in each wrapper div element:

&:before {
  width: 0;
  height: 0;
  border-style: solid;
  border-width: xxxpx 0 0 xxxpx;
  border-color: transparent transparent transparent #fff;
  content: '';
}

&:after {
  width: 0;
  height: 0;
  border-style: solid;
  border-width: 0 xxxpx xxxpx 0;
  border-color: transparent #fff transparent transparent;
  content: '';
}

Among them, the before pseudo-element is used to generate the upper left corner triangle of the inclined block, and the after pseudo-element Element used to generate the lower right triangle of the sloped block.

3. Notes

In the process of implementing diagonal overlay layout, you need to pay attention to the following issues:

1. The width of the diagonal block needs to be adjusted according to the screen. Adapt, otherwise it will lead to different display effects on different screen sizes.
2. The spacing width of the inclined blocks needs to be set to an appropriate value, otherwise the spacing between the inclined blocks may be too large or too small.
3. When setting the position attribute of the inclined block to absolute, you need to pay attention to whether the position attribute of its parent element is relative, otherwise it will lead to inaccurate positioning.

4. Summary

The above is the implementation method of diagonal overlay layout of WeChat applet based on PHP. The diagonal overlay layout is a relatively special layout method, which can not only increase the dynamics and beauty of the page, but also improve the efficiency of page use. I hope this article can provide some reference and help to WeChat applet developers when implementing diagonal overlay layout.
