Font smoothing and anti-aliasing rendering in CSS3
While looking at the official Drupal theme, I discovered an interesting non-standard CSS selector -webkit-font-smoothing, so I started playing with it. How to use css3 fonts to display smoothly
You must know that W3C has considered anti-aliasing rendering of fonts in CSS, such as font-smooth, but it may be due to the rendering of fonts by different operating systems and browser kernels. There are differences, and in short, it was not selected into a web standard. However, WebKit still retains a set of its own non-standard selectors to support anti-aliasing effects to make fonts display smoother.
-webkit-font-smoothingThere are three main properties:
none: No anti-aliasing
subpixel-antialiased (default): Subpixel smoothing is common in Mac OS and MacType For Windows
antialiased: Grayscale smoothing is commonly used in mobile devices such as Android and iOS
But after trying, my wooden eyes can’t tell the difference between the latter two at all. 
And this non-standard CSS is only applicable to most mobile browsers and desktop browsers with WebKit core such as Safari and Chrome. As for the IE series, you don’t support it yourself, blame me~
Let’s take a look at the actual effect. First of all, it does not use anti-aliasing rendering:
The next step is to use -webkit-font-smoothing: subpixel-antialiasedThe effect of anti-aliasing rendering smoothing:

After testing, it was found that font anti-aliasing is generally included in the built-in basic properties of the browser. But to be on the safe side, let’s add it manually
