Safari applies my styles normally on page load for any size. However, it won't apply desktop styles if the window has been sized for mobile since at any point since the last reload.
To most easily see/trigger the behavior, open the site in Safari 13 at desktop size and see the desired layout (most notable here is the navigation bar). Resize the browser down to mobile layout (be sure the navigation switches to hamburger mode), then back up to the desktop layout. (You may also load the site at mobile first, then simply widen the window.)
See test case here: https://www.davincilabs.com/
Normal behavior (as on load):
After browser resize (Safari 13 only):
If you inspect menu elements, you will see that styles-l.css and navigation-desktop.css apply. After resizing up, the style sheets no longer apply.
IMPORTANT: This does not appear to be a JavaScript problem! The behavior still occurs if you disable JavaScript from the develop menu.
To recap:
Found in Safari 13 ONLY. Earlier versions of Safari that we have tested so far do not experience this. Other browsers tested (Chrome, Firefox, Edge) do not experience this.
I have only experienced on desktop. This might affect phones as well but it's impossible to reproduce with my test case; I'm not using any breakpoints small enough.
Initial page load is always correct
Issue triggers when window is enlarged greater than the mobile breakpoint
Safari appears to be no longer applying an entire loaded style sheet file (styles-l.css) to the page layout
Occurs even with JavaScript shut off
This must be fairly rare as I can't find other occurrences after a lot of searching, but it's affecting multiple sites I am working on. Finally, if you cause Safari to reconsider CSS rules in the inspector, (such as by manually editing the parameters of a media query,) Safari will instantly redraw the page correctly.
I had the same problem.
I don't know why but I have this problem just with the store on Magento 2 and with Safari 13. (Also others big e-commerce like The Protein Works, Bulk Powders, sigmabeauty ecc)
I fixed it with macOS Catalina 10.15.7 and Safari 14.
I am working on a web application, and I am facing a lot of issues when zooming
Here is a blueprint of the architecture of the page :
lately the client asked us to make the application adjustable with different resolutions, the original one is : (1280*1024), now We have added some media queries so it will fit in (1600*900) & (1920*1080), currently the application is working fine in these resolutions, but we are facing one problem which is triggered when the user zooms in or out, the page becomes messed up.
I have looked online, and I've found that I need to wrap the header and content in one single div, and assigning margin : 0 auto; with a max-width & max-height..., I did that but I still have the same issue.
Apparently the problem disappears when I use the emulator in Internet Explorer and I precise the resolution such us Below the application is working fine when zooming, but when the Emulator is on default mode the problem occurs.
The application is very old and it's working only in IE11 compatibility mode.
So my question is, how to fix the size of the page in different resolutions without modifying the emulator?
The application works fine when you use the Emulator because you define the resolution for it and the resolution won't change when zooming in this situation.
But zoom itself is a behavior which will make the browser behave as different devices and will definitely change the resolution, so the appearance will be different.
I think you just need to make media query with the commonly used resolutions. For more information, you could refer to this thread.
I'm normally develop on hi-dpi machines (a Macbook Pro, 2018 MBA, iPhone, Pixel 2 XL). Often I'm styling something or drawing a diagram and I need to know how it's going to look when displayed on a low-dpi machine (pre 2018 Macbook Air, majority of PCs, etc...)
I tried using Chrome's devtools device emulation and it let's you set a devicePixelRatio but it's still actually rendering text and SVGs and styles in hd-dpi. (Not really sure what that setting is doing. I made to custom settings, one 1280x780 dpi = 2, and another 1280x780 dpi = 1 and switching between them changes nothing. My guess is it only changes what "windows.devicePixelRatio" and maybe what images load if using srcset and css media queries.
Is there a way to simulate low-dpi in Firefox or Chrome? Basically to get the browser to render at 1/2 the resolution and then expand with nearest neighbor filtering. I realize it will not be a perfect representation but my hope is it's good enough to check that thin lines in a diagram for example are still readable.
Well I figured out one way, at least on Mac.
Turn on OS Zoom in Settings under Accessibility
Be sure to uncheck "Smooth images". Then in Chrome or Firefox set the zoom level to 50% and turn on the OS level zoom Option+⌘+8
This does a pretty good job of looking like a low-dpi display.
I have website which is having layout issues on certain devices which I believe I've tracked down to high res displays which also have the display scaling in windows 10 set to 200%. (not 200% in the browser, but in the display settings in the Windows Control Panel)
The problem is I don't have a device which can duplicate the resolution of these devices, which is 2736 x 1824 (it's a MS Surface Pro). Oh yeah, this only happen with Edge...
I know of sites which have VMs which will run different browsers for testing purposes, but I don't know of any which allow you to choose your resolution. Without going out and getting a hold of this specific machine, how else can I debug this issue?
You could create a custom device in the developer console, and simply display it at whatever scale actually fits on your screen. For instance, create a custom device with that particular resolution, then in the developer console on Chrome you can view it scaled down 50% (if your own resolution is 1920x1080) so that the whole thing is visible.
Turned out none of the emulation/scaling options in the dev console would emulate what was really happening. I ended up remoting into the customer's computer so I could do my own debugging on there and resolved the issue.
Seems like Edge v 44 was computing some CSS calc function for a div height incorrectly (off by 1 or 2 pixels) which was making some divs push out and mess up the layout.
The fix was to tweak the CSS so the calculation wasn't required.
I'm working on putting together a liquid style-sheet and it works wonderful. One thing that I've noticed is that my browser window in Chrome won't resize below 400px it just gets stuck there and in FF as I scale down it it just stops at around 400px and then pops a horizontal scroll bar.
When I open the site on my phone it looks perfect at around 320px, so I know it does scale lower than 400px.
I was curious if anyone knew if this was a browser/desktop thing or if I should be looking at something other than my CSS. I don't have any min-width declarations so i'm not sure what could be causing this.
Again on desktop it scales down to a min-width of about 400px and stops, but when I open it up on my phone it scales to the size of the phone screen which is roughly 320px... curious why at the very least it won't scale down to the 320px on desktop.
-edit-
Also I'm not sure if this matters but Opera allows it to scale down to pretty much nothing... So it works with Opera and not in Chrome or FF... any ideas?
Chrome cannot resize horizontally below 400px (OS X) or 218px (Windows) but I have a really simple solution to the problem:
Dock the web inspector to the right instead of to the bottom
Resize the inspector panel - you can now make the browser area really small (down to 0px)
Update: Chrome now allows you to arrange the inspector windows vertically when docked to the right! This really improves the layout.
The HTML and CSS panels fit really well and you even open a small console panel too.
This has allowed me to completely move from Firefox/Firebug to Chrome.
If you want to go a step further look at the web inspector settings (cog icon, bottom-right), and goto the user agent tab. You can set the screen resolution to whatever you like here and even quickly toggle between portrait and landscape.
UPDATE: Here is another really cool tool I've come across. http://lab.maltewassermann.com/viewport-resizer/
this may be because of the addons you installed on your browser. remove or hide all addon icons from the tool bar and try re size. when there are addons browser only resize the address bar and keeps the addons visible.
Update: 7/14/2013
With the latest chrome version, now you can re-size the address bar and it will hide the addons automatically.
I was stumped as well but ended up with a simple solution. I just created a HTML file with a link to open a new window:
Open!
This new window has nothing but the address bar and Chrome lets me freely resize this down to 111x80.
nayan9's solution works great, and can be put into a bookmark without having to create a html file. In Chrome, create a new bookmark with URL:
javascript:(function(){window.open('ANY_URL', '','width=320,height=480');})();
And give it a name of "Open Small Window" or something similar. This will allow you to easily open windows without size restrictions within chrome. Note that just copying this into your address bar won't work - chrome strips the "javascript:" out.
In case you want to reduce your screen width to emulate different devices (and why else would you want to do this?):
Chrome now has an Emulation section in its inspector, activated by clicking the little phone icon in the top menubar (between the magnifying glass and Elements):
Emulation mode allows you to set the viewport size to all common mobile screen sizes, among other nice features, like emulating touch, geolocation and even accelerometer input:
Adding to what nayan9 and drinkdecaf said, you can just throw document.URL into the call to window.open to see the page you're currently viewing in the 320 window. You might want to add some more to the width if you're expecting a scrollbar.
javascript:(function(){window.open(document.URL, '','width=320,height=480');})();
I am lazy, to make it even easier, let the bookmarklet ask the user for sizes :-D
javascript: (function() {var width = prompt('Enter window width:', '320');var height = prompt('Enter window height:','480');var url = prompt('Enter window URL');if (url.indexOf(':') < 0) {url = 'http://'+url;} window.open(url, '','width='+width+',height='+height);})()
in chrome the icons of your addons in the top right corner cause the problem
-> resize the adress-bar (where you type the urls) to maximum width (drag the bar at the right edge to the right)
or disable the icons
The DevTools in Chrome have moved on substantially from when most of these answers were posted. The best way to address this issue now is to use the emulators that are built into Chrome.
To use the emulators open DevTools (press F12) and then click on the following icon to toggle the Device Toolbar:
This will then allow you to emulate whichever mobile device or viewport size you want to.
I found a quick workaround for this.
Just install the Responsive Web Design Add-on to Chrome, and it will open a separate window without the address bar and tabs, which can be scaled down to 10 px or less.

I've been experiencing similar issues and just found a good work around. Open up your chrome devtools and in the top left, there's a little screen and ipad icon. Click that and it opens a mobile view of your page. You can set it to predefined devices or a custom resolution. Pretty nifty actually.
Another easy solution is to click Strg+Shift+N to enter Incognito Mode. There you can resize your Browser window as you like.
I like this tool because it lets you switch quickly and also switches between portrait/horizontal easily for mobile sizes. It also allows you to make a personalized bookmark let, so if you design for obscure resolutions frequently, you can save them and use them.
I had to use one of these tools because even with the above answer I couldn't get my window to scale to 320 properly, this tool seems to be a faster solution overall.

I'm always running into this issue with pinned tabs. Chrome will not resize below a horizontal width of eight visible pinned tabs if there are any! Just detach the tab that you want to resize to solve this ...
For a web developer, in order to test the responsiveness of their website in mobile or tablet whose size is less than 500px or minimum width then use developer tools to test in small screens.
For testing, go to developer tools and press ctrl+shift+M or click the device icon at the top left of the developer tools screen to toggle device mode. If the device icon is in blue colour, then you can test your website responsiveness by changing the browser window.
This is my first contribution to the Stack Overflow community, and it is my effort to give back to all you wonderful people who have made internet such a powerful tool.
Now to answer:
Safari, has this cool feature.
You need to activate safari developer option in preferences.
Screenshot of setting up preferences in Safari to activate developer menu
Once activated you can access bunch of very powerful developer tools.
One of this tool is Viewport adjustment which can used to test your website responsive layout.
To activate responsive lay out testing, one can use the shortcut Command+Ctrl+R
to activate safari view port adjustment option.
This will give you enough control to test your website on various view port sizes.

A lot of smart phones scale the page to fit into their screen size using zooming. Your minimum page width is probably 400px. Without any example code, I think that's all that can be said.
