Browser doesn't scale below 400px?

Question

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?

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.

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.

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.

Answer 4

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.

Answer 5

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.

Answer 6

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 ...

Answer 7

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:

Answer 8

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.

Answer 9

Another easy solution is to click Strg+Shift+N to enter Incognito Mode. There you can resize your Browser window as you like.

Answer 10

Chrome cannot resize horizontally below 400px (OS X) or 218px (Windows) but I have a really simple solution to the problem:

1. Dock the web inspector to the right instead of to the bottom
2. 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/

Answer 11

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.

Answer 12

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);})()

Answer 13

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');})();

Answer 14

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.

Answer 15

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:

<a href="javascript:window.open('your_url_here', '','width=320,height=480')">Open!</a>

This new window has nothing but the address bar and Chrome lets me freely resize this down to 111x80.

Answer 16

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

Answer 17

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.
