Night mode allows you to change the background of the application interface to darker colors so as not to tire your eyes when working with programs in the dark. As a rule, such a function is available in e-books (e-books), since reading books on a light background in the middle of the night is not so comfortable and tedious.

A bright theme is not suitable for viewing at night when the room is dark. But there is a way to enable hidden YouTube night mode, which changes the background of the interface to a dark gray. It can only be enabled in Google Chrome, but will likely be available in all browsers soon. Check out how to make a dark background on video hosting.

In 2016, bloggers accidentally found a test version of YouTube.com's updated, more minimalist design. In May 2017, it became known: testing is not over yet, but Google is already offering the updated YouTube “bow” as an option, and anyone can use it.
The redesign was based on principles - the design language that Google has implemented in the latest versions of Android.
Fred Gilbert, Head of User Experience at YouTube:
“We don't want the UI to get in the way of users. Content should always come first. "
What has changed in the updated YouTube?
- The video titles in blue are now black and do not distract attention;
- "Trimmed" sidebar sidebar;
- YouTube logo, search bar, and channel icons have become smaller (and the latter are also round).
- Added auto-loading of new videos when scrolling down (you no longer need to press the "More" button).
Needless to say - it turned out great, and returning to the old version of YouTube leaves a painful impression.
But there are changes not only externally, but also “under the hood”. The new YouTube site is powered by the Polymer framework.
Thanks to him, the service works a little faster, but the most important thing here is that Polymer allows you to add new functions, such as night mode (how to enable it is described below). The latter changes the light "background" to black, and as a result, watching video at night becomes much more comfortable - the black color does not "hurt" the eyes. "
