Css fieldset/legend with flex and float bug
When I want legend inside the filedset, not on the border as default browsers design, I set float: left to the legend. It works in every modern browser - Safari too. The problem is when the filedset itself is set to display: flex. Float propertie of the legend is ignored. In other browsers this approach works fine and the float stays and the legend is inside of the fieldset as we expect.

Text-shadow + column-count adds unexpected whitespace at beginning of second column
Howdy! On Safari, when using the column-count CSS property to split text into multiple columns, I've noticed that when applying a text-shadow, there is an unexpected whitespace created above all subsequent columns. I've put together a codepen demonstrating the issue and its reproducibility on Safari (using latest as of this posting: Version 17.6 (19618.3.11.11.5)) Codepen: https://codepen.io/cubepresser/pen/ExqvzjL Expected behavior: Actual: I tested this on the latest versions of Chrome, Firefox and Edge. This bug does not occur. Expected behavior is that there should not be an extra line added to the beginning of the second column, third column, etc. Here's some code if that codepen link doesn't work: HTML: <p id="example">0000000000111111111122222222223333333333</p> CSS: #example { font-family: monospace; max-width: 20ch; column-count: 2; column-gap: 0; word-break: break-all; line-break: anywhere; text-shadow: 0 0 4px black; }

Safari renders html elements in wrong position
Check the attached screenshot, web inspector shows the right element size and position, but Safari renders it in a wrong place. The element reacts on mouse events also correctly - according to its real position. Here you can find the live example https://3dflipbook.net/css-layer-highlight This is a regression issue, it was working fine in 15.6. Bug tracker: https://bugs.webkit.org/show_bug.cgi?id=278898 Please fix the issue.

Safari, iOS, linear-gradient and color-mix issues
I have a web site that uses CSS linear-gradient with color-mix for a background of a division. It shows up just fine in Safari on iOS and iPadOS 17.4.1. When do a screenshot, and select "Full Page", the background-image becomes all black and the text in the division is unreadable. Here is an example of what I am doing. div.ugly { background-image: linear-gradient(to right, yellow, color-mix(in srgb, red, blue)); } Any ideas how to get this to not turn black? I've tried using a print media query but the "Full Page" screenshot does not use that. It looks like it might be a bug in iOS/iPadOS. Thanks, Mike

Scroll Bar Issue in Safari
Hello, I've encountered an issue with the scrollbar functionality on my webpage specifically when accessed through Safari. Despite its functionality on other browsers and devices, Safari on iOS 14 displays only the native scrollbar during scrolling, contrary to the desired behaviour of consistently showing the scrollbar. &::-webkit-scrollbar { height: 2px; } &::-webkit-scrollbar-track { background-color: "white"; margin-left: 4px; margin-right: 4px; } &::-webkit-scrollbar-thumb { background: "orange"; } }

Videojs player issue on iOS 17 software update
Hi, After iOS 17 software update, we've encountered an anomaly with the video element within our videojs player. Upon video load, there's a noticeable shift and recentring of the video to its correct position. This issue becomes more pronounced when the player is in a horizontal orientation while the video being played is vertical. Additionally, we've observed resizing and cropping issues during the initialization of the player, which were not present in earlier versions. In our current implementation, we have a canvas element inserted before the player. Due to resizing, the video sticks to the canvas and fails to return to the correct position. <div> <video class="vjs-tech" webkit-playsinline playsinline src="hls video source"> </video> <canvas style="filter: blur(15px)" class="vjs-tech custom-canvas" width="412" height="320"> </canvas> </div>

Smart Banner Help
Hello, I am looking for help with displaying Smart Banners on mobile devices. What is the preferred coding that can have Smart Banners appear on all devices? I am having an issue where an Smart Banner is not properly functioning as I would like it to. I would like the CTA (Call-To-Action) to be positioned on the top of a mobile screen. If a user has the mobile app already, it should read OPEN and opens into the app when it is clicked. If the user does not have the app, it should read GET and take a user to the mobile app store when it is clicked.

Strange counting in Safari
First: don’t tell me about webkit-reporting. I just get a 502 from there! Ok, what’s the problem? I made an example telling it all: <html> <head> <style> .ext { display: none; color: cyan; } body { max-inline-size: calc(100vi - 12px); &:not(:has(:target)), &:has(p.dft:target) { #ext { display: none; } #dft { display: block; } } &:has(p.ext:target) { #ext { display: block; } #dft { display: none; } } &.ext li { display: none; } &:has(.ext:target) { & li.ext { display: revert; } } } header > p > a::before { color: orange; content: "click me >>> "; } ul { display: flex; } li { margin: 1ex; list-style-type: none; inline-size: max-content; } .yes li::before { font-size: 70%; color: yellow; background-color: blue; content: "(" counters(total, ":") ")"; } ul.nGrp { display: inline flex; counter-reset: nameIndex; & li::after { display: inline-block; counter-increment: nameIndex; font-size: 75%; color: red; vertical-align: sub; content: "(" counter(nameIndex) ")"; } } header { inline-size: 100%; font-size: 2rem; text-align: center; } article { counter-reset: total; padding: 1ex; margin: 1em; &::after { font-size: 3em; color: purple; content: "— [" counter(total) "] —"; } li { counter-increment: total; } outline: 1ex groove purple; } </style> <title>Strange Safari-Count</title> </head> <body lang="de"> <header> <hgroup><h1>Strange counting without <code>:before</code></h1><p>different from FireFox!</p></hgroup> <p id="dft" class="dft"><a href="#ext">More?</a></p> <p id="ext" class="ext"><a href="#dft">Less!</a></p> <p><code>:before</code> doesn’t inherit parent’s display:none?
