If some sticky elements won't work on Safari for iOS (13.83%) then that's not that big of a deal, since it's uncommon to use sticky elements on mobile devices anyways (except for maybe the header). If this is something that you prefer over manually wrapping all elements that overflow the viewport, then that is completely understandable. If you do not feel like wrapping every single element that overflows the viewport, and you find it okay if sticky elements won't work on some specific modern browsers, then I suggest using hidden as a fallback for browsers that do not support overflow: clip.Įlements with position: sticky will, in this case, not work for browsers that do not support overflow: clip. Use overflow: hidden as a fallback for overflow: clip If those wrappers contain elements that use position: sticky, then I feel sorry for you I guess it's time to wait for support. Then, those wrappers should use overflow: hidden. If you really want position: sticky to work on all modern browsers, then you should consider not using overflow: hidden on the or any wrapper surrounding the main content, but rather put a wrapper around elements that will overflow the viewport. Your viewport, that is the default scroll container. So, the clip value does not make it a scroll container, so the window is still the scroll container. It hides the overflowing content, but does not turn the element into a scroll container. Mozilla Firefox versions 80 and lower have a non-standard name for value clip, which perfectly describes what it actually does: -moz-hidden-unscrollable. You did not specify a height to the scroll container, and why would you? Since it is now a scroll container, it needs a specified height in order for position: sticky to work. The hidden value only disables scrolling for the user, while keeping the option for programmatic scrolling, thus making it a scroll container. The clip value does the same as the hidden value, except for that it completely disables any form of scrolling. If you are interested in improving the performance of your web design, consider reading a post about lazy-rendering using content-visibility: auto and contain-intrinsic-size. It has no way to determine whether to clip on the x-axis or the y-axis, unlike you can with overflow-x and overflow-y with value clip. So that's a slight improvement compared to overflow.Īlso, contain is a CSS property that is used for improving performance, not necessarily for controlling overflow of content. It has been around in Google Chrome since version 52, though. Sadly, this CSS property is also not supported by Safari. If you use contain: paint, then all the descendants that overflow the container, will get clipped to the border-box. There is, however, another rather new CSS property: contain. Samsung Internet versions 4 - 14.0 (1.14%).Which is not enough to implement this without a fallback. Let me tell you, at the time of writing this (October 2021), the support for this new CSS property is 73.09% globally. Browser support for CSS declaration overflow: clip Unfortunately, there is a but to this one. This new value completely solves this problem. There is, however, a rather new value for the overflow-property - it's called: clip. However, that's not what you want to do (right?), because you don't want to set a fixed height on the sticky element's ancestor or parent element. Some articles claim that the solution to this is to make sure that the ancestor or parent element has a specified height. How to make position: sticky work with an ancestor's or parent's overflow: hidden? That's disappointing, because you really needed that overflow-x: hidden on the -tag or on any other wrapper, to prevent horizontal scrolling due to overflowing content. It's because an ancestor element has one of the following values for the overflow property: hidden, scroll, or auto. Avoid creating entirely different versions of the same site, instead hide element responsively for each screen size.If you've ever tried sticky positioning, then you have probably wondered why CSS position: sticky is not working for your web design. Block block (or $ke圜 ) Hiding elementsįor faster mobile-friendly development, use responsive display classes for showing and hiding elements by device.
