HTML <video> style Attribute

HTML <var>

HTML <wbr>

A style attribute on a <video> tag assigns a unique style to the video control.

Its value is CSS that defines the appearance of the video element.

Example

#

A style attribute on a <video> element.

<video class="video" controls 
       style="width:300px; height:240px; outline:none;
              border: 5px solid #45c9d0; padding: 10px;">
  <source src="/media/movie.mp4" type="video/mp4">
  <source src="/media/movie.ogg" type="video/ogg">
</video>

Using style

#

The style attribute specifies the style, i.e. look and feel, of the <video> element.

A style contains any number of CSS property/value pairs, separated by semicolons (;).

The style attribute overrides any other style that was defined in a <style> tag or an external CSS file.

This inline styling affects the current <video> element only.

Syntax

#

<video style="CSS-styles">

Values

#

Value	Description
CSS-styles	One or more CSS property/value pairs separated by semicolons (;).

More Examples

#

A style attribute on a <video> element.
Clicking the button toggles the video size.

<video id="myvideo" controls
       style="width: 320px; height: 240px; outline: none;">
  <source src="/media/movie.mp4" type="video/mp4">
  <source src="/media/movie.ogg" type="video/ogg">
</video>

<br/><br/>
<button onclick="toggle();">Toggle class</button>

<script>
  let toggle = () => {
     let element = document.getElementById("myvideo");
     if (element.style.width === "320px") {
       element.style.width = "480px";
       element.style.height = "360px";
     } else {
       element.style.width = "320px";
       element.style.height = "240px";
     }
  }
</script>

Code explanation

The style attribute assigns width and height to the <video>.

Clicking the button calls JavaScript which changes the element width and height.
