Flex grid not working on iOS 8 #25429
Comments

but you use col-md-2 col-md-10 so ... this behavior is correct ?... no ? |
|
@jipexu Whoups, wrong screenshot attached. Edited. Thanks for the heads up! |
|
This behavior is not as expected using Bootstrap - the columns should wrap when the viewport is only 320px wide, as per the Chrome emulator. |
|
In case Bootstrap is not supposed to work on iOS 8, it would be handy to have some kind of CSS/JS snippets to make it work. I guess the issue is Safari iOS 8 doesn't support flexbox. |
|
It works using verdor prefixes, e.g. |
|
I'm guessing something is out of whack with our autoprefixer settings. This is meant to be functioning given we include our |
|
Perhaps more info at #24941 (comment). |
|
If you look in the autoprefixer settings, iOS is set to >=9, maybe it will help if it is dialed back to >=8 |
|
Is that worth it, though? iPhone 4, iPod 4 and iPad 1 and older are the only devices that can't go beyond iOS 8. All these devices are from 2010. They are collectively worth about 1% market share from iOS devices. According to the documentation, Bootstrap 4 should only be supporting iOS 11, not 9 and up. Nevermind 8. |
|
@mdo: is iOS 8 supposed to be supported? |
|
@mdo: from our migration docs:
So we need to fix this situation. What should the minimum iOS version be? |
|
I don't think flexbox is supported properly in iOS 8 Safari and you need vendor prefixes, so makes more sense to start at iOS 9.3 Safari anyway for reasonable flexbox support. |
|
I think actually we'll want to pass on this and update our docs to be iOS 9+. iOS 8 is 1.19% of the iPhone market share according to https://data.apteligent.com/ios/. The move to iOS 9+ came in #22943 last June. |
|
In fact, I don't think we list our current browserslist anywhere. Maybe we could load it from package.json on build time, but I'm not sure it will work since package.json isn't in the Anyway, your call. I agree that iOS 8 is old plus anyone can just use autoprefixer. |
|
|
|
@mdo: What do you think about this? If you still want to drop this, please close it :) |
|
I encountered the same problem on my iPhone6 plus, iOS8.2. The solution is to use prefixfree.js (https://github.com/LeaVerou/prefixfree), it can make flex-wrap work correctly with "-webkit" prefixes. |

Now it seems only Chrome (at least on Win and Android, not tested on macOS) is the odd one out. However, we should really make sure the custom validation messages are also tied correctly to their relevant form controls - need to dig out the PR that will ensure that. * Add note about resetting form appearance after submission xref twbs#25626 * Add `type="button"` to `<button>`s in accordion example (twbs#25643) For consistency.

Closes twbs#25546 This adds `form-group` to add the same vertical space to the `form-check` as in other grouped controls used in form sample markup. Thanks! * Remove disabling of stylelint rule This file no longer has intentional indentation errors * Add focus states to custom docs buttons * Fix typo of example in hiding doc * dist * Fixes twbs#25703 * Add tabindex attribute to disabled buttons sample. Closes twbs#23361 (twbs#25680) As discussed in issue's comment: https://git.io/vAuPW Thanks! * Remove unused variable (twbs#25670) This variable is not used anywhere. Leftover from twbs#18373. * docs skippy partial (twbs#25750) * load skippy markup from includes * display on xl viewport See issue twbs#25711 * Fix leftover reference to v4.0.0-alpha.6 Running `./build/change-version.js v4.0.0-alpha.6 v4.0.0` fixed this, so the version change script works fine. I'm presuming instead this change was just omitted from 35f80bb, and then wouldn't have been caught by subsequent runs of `change-version`, since it only ever replaces the exact old version string specified. * Replace img-fluid by w-100 to conform with HTML * Adding a variable to handle the change of a modals border-radius.

They provide 15 different icon styles, exportable as fonts or svg * Collapse with flex elements - simple approach (twbs#25806) * twbs#22600: prevent display:block for visible content * allow transition for elements with show class * re-use gray for bd-example border / background (twbs#25751) * Fix caret alignment (twbs#25719) * Allow customization of breadcrumb border radius (twbs#25807) * Clean shell scripts (twbs#25704) * Replace "loose" HEX values with their respective variables (twbs#25672) * Fix examples' issues twbs#25664 and twbs#25388 (twbs#25665) * Prevent sign-in form from going outside viewport (twbs#25388) * Workaround IE centering bug * Disable link functionality on disabled `btn-link` (twbs#25645) Future-proof disabling of clicks on disabled `btn-link`.

It's == "it is" 2. The subject of the sentence is "Only one" (not "these") so the verb must agree with it. Feel free to do nothing with this change, use it, etc - I just saw this while reading through the code. * Dashboard updates (twbs#26179) * Update Dashboard example - Replaces .sticky-top on .navbar with .fixed-top - Adjusts padding on main content area and sidebar to account for fixed navbar - Move to padding in sidebar instead of top: 48px; fixes Firefox rendering issue - Adds new .shadow utility for a little extra cherry on top - Moves sticky styles to separate feature query ruleset to avoid IE rendering issues * Add .w-100 to chart to fix IE horizontal scroll from label that extended past viewport * Update offcanvas example for IE support - Replaces CSS variables with their appropriate hex values - Fixes the broken navbar transition by moving from 2D translates to using position - Fix broken IE navbar toggler placement with some utilities (not necessary anywhere else, but necessary given flexbox quirks) * Allow non-string content as breadcrumb divider (twbs#25581) * Allow url(), attr(), none,... as breadcrumb divider * Update breadcrumb divider docs * Pagination move `.page-link:focus` outline value to variable `$pagination-focus-outline` so we can unset it via Sass and don't have to re-implement browser defaults * dist * Use https when possible. * Fix broken URI fragments and redirects. * docs: Switch to StackPath's URL.

There's no clean way to shim this for non-supporting browsers, but arguably these browsers would have further problems with pure `<dialog>` usage anyway, and it's up to authors to then use different elements/shims. * Resolve twbs#26262: Add deprecated warning (twbs#26292) * Bump version to 4.1.0 for remaining files. * breadcrumb.md: Remove trailing space. * Suppress text-hide deprecation warning (twbs#26242) * Update devDependencies.

On Edge and IE the label is displayed always and any text input overlaps the label which makes it unreadable. The fix here targets Edge and IE and makes the form behave normally, the labels are hidden and the placeholder color is standard. * dist * feat(dropdown): add original click event * Add broken-link-checker. * fix(tooltip): get tip on placement change

Pretty much like #22223

And this is the Bootstrap website:
Documentation mentions you support the latest stable versions of major browsers––I'm not sure if Safari on iOS 8 is included among these.
