Fonts provided by CSS are available to developers.

What are web-safe fonts?

Web safe fonts

are fonts which are supported by all the browsers on any device. These fonts enable the developers to display them properly even if they are not installed in the users’ device. Before web-safe fonts were developed, browsers would display generic fonts such as

Times New Roman

if the font was not installed on the user's local system. However, the developer cannot detect whether the font is displayed correctly on the server side. This results in a poor user experience. Using web safe fonts resolves this issue. During web designing, if you use web safe fonts, you can be rest assured that your fonts will be displayed as it is in every device.

element{
   font-family: font1;
}

Kinds of web safe fonts

There are six web-safe fonts. They are as follows −

Serif - These fonts contain small protrusions that are present in the body of each letter. They are easier to read on screen and printed forms. Times New Roman is a serif font.
Monospace - These fonts are fonts with equal spacing between letters. Space Mono, Courier, Inconsolata, etc. are all fixed-width fonts.
Sans serif fonts - These fonts are the opposite of serif fonts. They do not contain small protrusions. Arial, Helvetica, Futura, Calibri, etc. are some examples of sans serif fonts.
Fantasy - These fonts are highly stylized and decorative. Papyrus, Herculanum, Luminari are fantasy fonts.
MS - These are the fonts introduced by Microsoft. Trebuchet MS, MS Gothic, Georgia etc., are MS fonts.
Cursive Script - These fonts are similar to cursive handwriting. Brush Script MT, Broadley, Monarda, Raksana, etc. are some cursive fonts.

What is the fallback font in CSS?

CSS offers two types of font families for web designing. These are generic font families like serif (Times New Roman, Georgia, etc.,) and the individual font families like Arial, Calibri etc.,.

A common font family has a number of similar-looking fonts, so if a primary font is not available on the user's system, there is a

fallback

mechanism that contains a list of similar font families that can be used instead. These fonts are called alternate fonts. They are used as backup in web design because no web font is 100% safe. There is always the possibility of error.

Backup

Fonts solve this problem by acting as a backup. Font families that are web-safe fonts can also be set as fallback fonts. Some examples of alternative fonts include cursive, fantasy, monospaced, etc. grammar

element{
   font-family: font1, font2, font3, font4;
}

Font2, font3, font4

are the fallback fonts which are used as backup. If browser doesn't support font1, then font2 will be displayed. If not font2, then font3 is used and so on. Example

<!DOCTYPE html>
<html>
<head>
   <title> Fallback fonts </title>
   <link rel= "preconnect" href= "https://fonts.googleapis.com">
   <link rel= "preconnect" href= "https://fonts.gstatic.com">
   <link href= "https://fonts.googleapis.com/css2?family=Roboto&display=swap" rel= "stylesheet">
   <style>
      .demo1{
         font-family: verdana,'cursive';
      }
      .demo2{
         font-family: cursive, Cochin, Georgia;
      }
      .demo3{
         font-family: Helvetica, arial, cursive, 'Times New Roman';
      }
      .demo4{
         font-family: 'Times New Roman', Cambria, Cochin, Georgia, Times, serif;
      }
   </style>
</head>
<body>
   <center>
      <h2> Fallback fonts </h2>
      <p class= "demo1"> This is an example. </p>
      <p class= "demo2"> This is an example. </p>
      <p class= "demo3"> This is an example. </p>
      <p class= "demo4"> This is an example. </p>
   </center>
</body>
</html>

In the above example, the font family of the text is font1. If any browser does not support font1 font family then we have a list of font families next to it which can be used as fallback fonts.

Conclusion

Using web-safe fonts in web design is a good practice as it ensures developers that it will be displayed on user devices. However, web-safe fonts are not 100% trustworthy. Therefore, it is possible to use CSS fallback fonts as a backup for fonts so that if one font family does not work, the browser can try another listed font family. It is good coding practice to use a common font family as the first font and then use the same font family for other options.
