Click “like” and then look, wechat search [Big Move the world] pay attention to this person without dACHang background, but with a positive attitude upward. In this paper, making github.com/qq449245884… Has been included, the article has been categorized, also organized a lot of my documentation, and tutorial materials.

Everyone said there was no project on your resume, so I found one and gave it away【 Construction tutorial 】.

CSS can generate a variety of shapes. Squares and rectangles are easy because they are the natural shape of the Web. Add width and height, and you get the exact size of the rectangle you want. Add border radii and you can turn the shape into a circle, enough border radii and you can turn the rectangles into circles and ovals.

We can also use ::before and ::after in the CSS pseudo-elements, which gives us the possibility to add two more shapes to the original element. With clever use of positioning, transformation, and many other tricks, you can create many shapes in CSS with just one HTML element.

Although most of us now use font ICONS or SVG images, it doesn’t seem to make a lot of sense to use CSS to make ICONS, but how to implement these ICONS using some skills and ideas is worth learning.

The bugs that may exist after code deployment cannot be known in real time. In order to solve these bugs, I spent a lot of time on log debugging. Incidentally, I recommend a good BUG monitoring tool for youFundebug.
