右上のウィンドウアイコンを長押しすると、切り替えられます。

別ウィンドウに切り替えられなくなってしばらく困ったので。

Tools to selectively copy HTML+CSS+JS from existing sites

Like most web developers, I occasionally like to look at the source of websites to see how their markup is built. Tools like Firebug and Chrome Developer Tools make it easy to inspect the code, but if I want to copy an isolated section and play around with it locally, it would be a pain to copy all the individual elements and their…

How to reposition chrome developer tools

The tools are opened on the bottom of the chrome window per default. This is a rather bad choice for a wide screen display since there is plenty of empty space to the right but not much vertical space to spare. Unfortunately, I have found no way to reposition the tools. I would like to have them on the side, similar to firebug.

The only option similar to…

"CAUTION: provisional headers are shown" in Chrome debugger

I noticed a strange caution message when looking at downloaded resources using Google chrome inspector (F12):

Caution provisional headers are shown

I found something possibly relevant, Network Panel: add caution about provisional request headers, but I could not fully understand it. Related questions can be found Chrome block requests

How to: Why {} + {} is NaN only on the client side? Why not in Node.js?

How to: Why {} + {} is NaN only on the client side? Why not in Node.js?

Why {} + {} is NaN only on the client side? Why not in Node.js?

While [] + [] is an empty string, [] + {} is "[object Object]", and {} + [] is 0. Why is {} + {} NaN?

> {} + {} NaN

My question isn’t why ({} + {}).toString() is "[object Object][object Object]" while NaN.toString() is "NaN", this part has an answer here already.

My question is why does this happen only on the client side? On the…

Chrome Nugget

For all those Front-End Devs that are like me and love to inspect element and play with the CSS/elements/DOM/what-have-you until your heart is pleased with what meets the eye and to ONLY remember that everything you just did was just in the browser inspect element and that you have YET to transfer all that wonderful markup to your stylesheet, and of course -- you've already refreshed the browser and everything went kaput. Well, FML indeed. And yes, that was a very long run-on sentence.

But let your heart be still -- there is an answer!

Drumroll please...

Ta-Da! Yes, God's gift to Front-End Devs. It autosaves the changes that you've made on Inspect Element and transfers your code to your editor. Works for JS too!

How to install DevTools Autosave:

Google "DevTools Autosave" or find it on the Chrome Web Store. It should be downloaded as a Chrome Extension and not an app.

Run Node.  - Here are some instructions to run Node depending on the machine you are using: http://howtonode.org/how-to-install-nodejs

After successfully running Node, open your Terminal and type:  npm install -g autosave If you are having issues running that command, please refer to this troubleshooting document: https://github.com/NV/chrome-devtools-autosave-server

Restart Chrome.

Open one of your local projects in a new Chrome browser and Inspect Element and play around with the attributes/elements.

Click Reload, and you will see that your changes didn't go away (Hallelujah!) and when you toggle back to your stylesheet, the new changes have magically transferred onto your stylesheet!

AHH-MAZING.

As a side note, if you don't want to keep retyping the autosave command in your Terminal each time you start your OS, you can also install it as a daemon (runs as a background process)... so you don't have to!

Here it is:

    npm run-script -g autosave autostart

Aye-aye Captain!
