Web visitors should be able to zoom as needed when browsing web pages. Zooming on a website can be helpful for users who need a larger text size for reading content and people who need a bigger click area for navigating a website.
Some website developers may consider adding a tag within the head of an html page to disable zooming to preserve a consistent look and feel across browser sizes. The trade-off is at the expense of usability for aesthetics. This is not a best practice for accessibility and usability of the website.
The following meta tag is the recommended tag for preserving zooming and scaling abilities as needed:
<meta name="viewport" content="width=device-width, initial-scale=1.0">
Inclusion of the following tag is not recommended:
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0”>
