在Windows或Mac上使用您最喜欢的网络浏览器(web browser)打开YouTube。如果您在多个浏览器中使用 YouTube，则必须为每个浏览器重复该过程。在本节中，我们描述了两个过程：第一个是您使用Google 帐户(Google account)登录时，第二个是您没有登录时。第二个程序也适用于隐私浏览。

如果您没有在网络浏览器上使用(web browser)Google 帐户(Google account)登录，YouTube会显示一个略有不同的页面。在右上角的SIGN IN旁边查找由三个垂直点表示的设置按钮。(Settings)单击设置(Settings)按钮，然后单击菜单中的深色主题(Dark theme)。

您是否一直使用YouTube的(YouTube)深色模式(dark mode)？
黑暗主题(Dark theme)可用于节省电池电量，在黑暗环境中保护您的眼睛，或者只是为了美观。我发现一旦我在YouTube 上打开了(YouTube)Dark 主题(Dark theme)，我就再也没有关闭它。你喜欢 YouTube 的黑暗模式(YouTube)吗(dark mode)？您打算再次将其关闭还是打算一直保持开启？在下面的评论中告诉我们。

How do I enable dark mode on YouTube in a web browser for Windows or Mac?
Open YouTube using your favorite web browser in Windows or on your Mac. If you use YouTube in more than one browser, you have to repeat the procedure for each browser. In this section, we describe two procedures: the first one when you are logged in with a Google account and a second for when you are not. The second procedure also applies to private browsing too.
When you are signed in on YouTube, click or tap the user account button on the top-right corner, and then click or tap the Dark theme entry.
YouTube displays a Dark theme panel with a description of this feature and a single switch. Turn the switch on to enable the Dark theme.
The Dark theme is applied instantly for both the menu as well as the entire YouTube site. Click or tap anywhere else on the page to close the Dark theme panel.
Keep in mind that the Dark theme setting is saved in a cookie in your browser. The setting does not affect the other browsers on your Windows computer, and it does not affect other installations of the same browser on other computers. If your cookies get deleted, YouTube reverts to the default setting which has the Dark theme off.
If you are not logged with a Google account on your web browser, YouTube shows a slightly different page. Look for a Settings button represented by three vertical dots, next to SIGN IN in the top-right corner. Click the Settings button, and then Dark theme in the menu.
YouTube displays a panel with a description of the Dark theme and a single switch. Turn the switch on to enable the dark mode in your browser.
The Dark theme is applied immediately to the menu and the entire YouTube site. Click or tap anywhere else on the page to close the Dark theme panel.
Remember that the Dark theme setting is saved as a cookie in your browser. If you sign in to your Google account, the Dark theme setting is preserved. Also, in a private browsing session, YouTube starts always with the Dark theme off because the private session has no access to the previous cookies. You can turn on the Dark theme for the current browsing session, but this setting is lost as soon as you close the private browsing window.
Do you use the dark mode for YouTube all the time?
The Dark theme can be used to save battery, to protect your eyes when you are in a dark environment or just for its aesthetics. I found that once I turned on the Dark theme on YouTube, I never went back to turn it off. How do you like the dark mode for YouTube? Do you intend to turn it off again or do you intend to keep it on all the time? Let us know in a comment below.
