How to change the HTML image in Dark mode

Learn, how to change the html image src in dark mode.

Normally, we use the prefers-color-scheme css media feature to detect if a user system is in light or dark mode.

To change the image in dark mode, we can use the <picture> tag in html.

Example:

<picture>
  <source
    srcset="dark.png"
    media="(prefers-color-scheme: dark)">  <img src="default.png" alt= "moving car">
</picture>

If the user system is in dark mode dark.png image is used, else default.png image is used.

Note: The browser will only download, one of those images based on the prefers-color-scheme. So that there is no bandwidth wastage.
