  • 1. How to add custom font into Html using CSS?

    Answer: using @font-face of css3 to import font. See an example below:

    @font-face {
        font-family: 'Roboto';
        src: url('Roboto-Regular.eot');
        src: local('Roboto Regular'), 
            url('../font/Roboto-Regular.eot?#iefix') format('embedded-opentype'), 
            url('../font/Roboto-Regular.woff') format('woff'), 
            url('../font/Roboto-Regular.ttf') format('truetype'), 
            url('../font/Roboto-Regular.svg') format('svg');
        font-weight: 400;
        font-style: normal;
    } 
    

    font-family: You can type any name you want.

    url: Set to the relative path of your site.

    How to use this custom font?

    - You can use normally like the default font. For example:

    h1{
       font-family: "Roboto";
    } 

     

    2. How to customize load font for fast performance?

    we have 2 problems that need to resolve with load a custom font.

    2.1 Block display text while loading the font file

    Text of your web page will not display while loading custom font file, You need display text with default font while loading custom font. To resolve this problem you can add font-display: swap property CSS into your custom font:

    @font-face {
        font-family: 'Roboto';
        src: url('Roboto-Regular.eot');
        ..................................
        font-style: normal;
        font-display: swap;
    } 
    

    2.2 Preload font file.

    If you preload the font file, you will help increase the performance of your website. You can see an example below :

    <link rel="preload" href="../font/Roboto-Regular.woff" as="font" type="font/woff" crossorigin /> 

    Push this code into the inside of the <head> tag.
