      Zoom

      The zoom property of CSS is useful in controlling the magnification level of elements.
      zoom is a non-standard property of CSS and it is advisable to use the transform: scale() function for the same output.

      Possible Values

      • normal: Specifies that the element should be rendered at its normal size.
      • reset: Specifies that the element should not de(magnify), unless the user applies non-pinch-based zooming. Not recommended, instead use unset value.
      • <percentage>: Any percentage value called zoom factor.
      • Value equal to 100% is normal.
      • Value more than 100% means element should zoom-in.
      • Value less than 100% means element should zoom-out.
      • <number>: Any number value that corresponds to a percentage value. For example: 1.0 = 100% = normal.
      • Value equal to 1.0 is normal.
      • Value more than 1.0 means element should zoom-in.
      • Value less than 1.0 means element should zoom-out.

      Applies to

      All the HTML elements.

      DOM Syntax

      object.style.zoom = "normal | reset | <number> | <percentage>";

      CSS zoom - normal Value

      Here is an example:
      <html>
      <style>
         p.normal {
            zoom: normal;
         }
         p.percent {
            zoom: 170%;
         }
         p.number {
            zoom: 4;
         }
         p.unset {
            zoom: unset;
         }
      </style>
      <head>
      </head>
      <body>
         <p class="normal">Normal size</p>
         <p class="percent">Zoom in percentage</p>
         <p class="number">Zoom in number</p>
         <p class="unset">Zoom settings reverted.</p>
      </body>
      </html>

      CSS zoom - <percentage> Value

      Here is another example:
      <html>
      <head>
      <style>
         div.box {
            height: 50px;
            width: 50px;
            display: inline-block;
            padding: 5px;
            border: 1px solid black;
         }
         div#m {
            background-color: orange;
            zoom: 200%;
         }
         div#n {
            background-color: lavender;
            zoom: 1.5;
         }
         div#o {
            background-color: palevioletred;
            zoom: normal;
         }
      </style>
      </head>
      <body>
         <div id="m" class="box"></div>
         <div id="n" class="box"></div>
         <div id="o" class="box"></div>
      </body>
      </html>

      CSS zoom - With number Value

      Here is an example, where the h1 element gets zoomed on hover:
      <html>
      <head>
      <style>
         p {
            border: 1px solid red;
         }
         p.percent {
            zoom: 170%;
         }
         p.number {
            zoom: 4;
         }
         h1:hover {
            zoom: 250%;
            text-decoration-line: underline;
         }
      </style>
      </head>
      <body>
         <h1>Hover to Zoom</h1>
         <p class="percent">Zoom in percentage</p>
         <p class="number">Zoom in number</p>
      </body>
      </html>

      CSS zoom - With Animation

      Here is an example, where the animation is added on hover along with zoom:
      <html>
      <head>
      <style>
         div.box {
            width: 25px;
            height: 25px;
            vertical-align: middle;
            display: inline-block;
            transition: transform .5s;
            padding: 10px;
         }
         div#a {
            background-color: rgb(58, 220, 22);
            zoom: normal;
         }
         div#b {
            background-color: rgb(239, 86, 137);
            zoom: 200%;
         }

            zoom: 2.9;
         }

            transform: scale(1.5);
         }
      </style>
      </head>
