Font scaling based on width of container using CSS - GeeksforGeeks

31 Mar, 2021
The font size can be set with vw (viewport) unit, which means the viewport width. The viewport is the browser window size. 1vw = 1% of viewport width. If the viewport is 50cm wide, 1vw is 0.5cm. That way the font size will follow the size of the browser window.Syntax:  
element {
    font-size: #vw;
    // CSS Property
}
Where # is a number relative to the container size.Example 1:  
html
<!DOCTYPE html><html>  <head>    <meta name="viewport" content="width=device-width, initial-scale=1" />    <title>Font Scaling</title>    <style>      #container {        display: inline-block;        background-color: green;        padding: 0.5vw 1vw;      }      .divtext {        display: table;        color: white;        font-family: impact;        font-size: 4.2vw;      }    </style>  </head>  <body>    <h1>GeeksforGeeks</h1>    <div id="container">      <div class="divtext">        Resize the browser window to see how the font size scales.      </div>    </div>  </body></html>
Output:  
Example 2: Media queries can be used to change the font size of an element on specific screen sizes.  
html
<!DOCTYPE html><html>    <head>        <meta name="viewport" content="width=device-width, initial-scale=1">        <title>Font Scaling</title>        <style>            h2 {                text-align: center;            }            div.example {                background-color: lightgreen;                padding: 20px;                text-align: center;            }            @media screen and (min-width: 601px) {                div.example {                    font-size: 40px;                }                .a{                    font-size: 25px;                    text-align: center;                }            }            @media screen and (max-width: 600px) {                div.example {                    font-size: 30px;                }                .a{                    font-size: 18px;                    text-align: center;                }            }            @media screen and (min-width: 800px) {                div.example {                    font-size: 60px;                }                .a{                    font-size: 35px;                }            }        </style>    </head>    <body>        <div class="example">Font size automatically adjusting        according to the width of the container</div>        <p class = "a">Change the width of the browser window        to see the font scaling automatically according to the        container size.</p>     </body></html>
