Handy Online Colour Picker

November 16th, 2012 by Adrian

If you are ever in need of selecting a colour and getting it’s HEX, RGB or HSB value, but can’t be bothered to fire up Photoshop, then just go to colorpicker.com

It’s a super handy online colour picker that also allows you to save up to 10 colours (and is persistent between browser sessions).

They also have a link to a chart showing the HTML Color Names.

It is also possible to link directly to a specific colour using a query string like this …


This is also handy for copy-and-pasting HSL values.

HTML, CSS & JS Online Code Editors/Playgrounds

October 10th, 2012 by Adrian

Over the last year or so there has been increase in the number of online HTML, CSS & JS editors. These are usually intended to demo small snippets of code that can be saved and shared. The feature sets of each service differ slightly, so you may need to try a few before you find the one that suits your specific requirements. Here are a few to get you started (with the most popular/fully-featured near the top). Many of these are based on CodeMirror or ACE.

jsFiddle – This is probably the most popular of these type of tools. It is pretty comprehensive and allows you to save and share your code. It includes HTML, CSS and JavaScript. You can choose from a wide range of pre-defined JavaScript frameworks, and you can also link to your own if it is not listed. It supports SCSS (Sass 3) and CoffeeScript if you are into those. You can choose from a variety of DTDs and modify the <body> tag (if needed). It has buttons for tidying up your code and JSLint support is included. The documentation is pretty comprehensive and the UI is nice and clean and easy to use. There is no code completion or code hinting as you type and your code doesn’t automatically run (you have to click the ‘Run’ button, or use the keyboard shortcut, to see your results). jsFiddle’s Twitter account is here.

JS Bin – This was created by Remy Sharp and is gaining in popularity. By default it has shortcuts to a huge list of JavaScript libraries, which you can include in your code. It supports many different flavours of HTML, CSS and JavaScript meta-languages (templating) like Markdown, Jade, LESS, Stylus, CoffeeScript, Processing, Traceur and TypeScript (Zen Coding is also supported). It has in in-built Console panel and the Output panel is automatically updated as you type. It automatically saves your code and there are a variety of sharing options. JavaScript error checking is provided via JSHint. A nice simple and clean tool, but again, no code completion or code hinting. A couple of great features it does have though is called Codecast (which enables people to watch as you type) and and Remote Rendering (which can be used to view your output on multiple devices in realtime). The documentation and help is pretty good too and the editor can be customised in great detail. Remy has done a fantastic job with this and he is always adding new and improved features. Follow JS Bin on Twitter.

Codepen – This tool was co-created by Mr CSS-Tricks (Chris Coyier) himself. It has a nice clean and well presented UI and the homepage is great for seeing other people’s demos (picked by the staff, or ranked as ‘popular’ or ‘recent’). The sharing and embedding options are good and forking other people’s projects is really easy (you can also see various Stats and Comments too). You can choose from a selection of colour schemes for the code editor (and select from three different fonts). Like jsFiddle and JS Bin, there is support for a variety of templating tools like HAML, Markdown, Slim, LESS, SCSS, SASS and CoffeeScript. It has built-in support for CSS Normalize, CSS Reset-prefix-free and Modernizr, and shortcuts to the latest versions of a few of the most popular JavaScript libraries. I think the strongest feature of this site is the way other people’s demos are showcased and easily accessible. This seems to be where all the cool kids hang out!

Dabblet – This tool was created by the very talented Lea Verou (who now works for the W3C), (check out her ‘Projects‘ page). This tool is focused on HTML and CSS (not JavaScript) and provides syntax highlighting and realtime updates. I particularly like the popup panels for CSS colors, gradients,  pixel dimensions, degrees and seconds. Plus the easy slider to increase the font size of the text in your code editor is handy. It has support for -prefix-free built in (it was created by Lea too) and is tightly integrated with github:gist. dabblet itself is open source and made available on github.

HTML5 Rocks Playground – This playground is really intended to show predefined examples of HTML5 code. You can’t use it to write your own snippets that can be saved and shared. But, for seeing how to do things (by the experts) in HTML, CSS, JavaScript this site is really great. Worth bookmarking.


jsdo.it is a Japanese online playground that has some very talented individuals using it. It is the sister site to the Flash AS3 online playground wonderfl. It pushes other peoples creations to the homepage (which is good for inspiration) and allows you to fork their code and modify it as you like. There are categories too (such as Application, User Interface, CSS, Game etc) which is useful. You can ‘Fav’ other peoples creations and you can ‘Follow’ them too (like you can on Codepen).

Tinkerbin – This editor has the basic features (separate panels for HTML, CSS, JavaScript and Output, but not resizable by dragging) and support for HAML, SCSS, SASS, LESS and CoffeeScript. You can save your snippets (each save is assigned it’s own unique short URL which you can pass on to other people) but it is pretty limited and doesn’t have some of the advanced features that jsFiddle, JS Bin and Codepen have.

Fiddle Salad – With this editor, you choose your coding style up-front. You are presented with the options of HTML (or HAML, Zen Coding, Markdown, CoffeeCup, Jade), CSS (or LESS, SCSS, SASS, Stylus), JavaScript (or CoffeeScript, Python, Roy), and then you hit the ‘Go’ button to start. The interface looks pretty busy (and not as clean as some of the other tolls listed above), but it does include a handy ‘Documentation’ panel which provides you with links to W3C’s CSS and HTML documentation, as well as jQuery (and the templating engines mentioned). Also, all the UI panels can be moved and resized which is pretty handy. Once you dig a little deeper you’ll realise that a lot of time and effort has gone into making this quite a fully featured tool. It has several different frameworks and libraries for you to choose from and select for import. It also has a number of ‘Tools’ such as validation and beautify tools (though some of these are just links to external websites). One thing that this has that some of the other tools don’t is code completion and code hinting (very useful in CSS). Overall I think this tool shows promise, but at the time of writing it doesn’t quite have the polish of jsFiddleJS Bin or Codepen.

ztxt – This is open source and available on github (thanks to Zevan Rosser). There is not a hosted version of this, the intention is that you download a copy of ztxt and then either run it locally using MAMP (or WAMP), or you host it on your own live webserver. I like the way that it can be used locally and allows access to your local filesystem. More information on ztxt can be seen on YouTube here.

Tinker – This is fairly bare-bones, but it does have a clean UI (with draggable editing areas) and offers syntax highlighting and saving (to a unique short URL). Clutter-free and to the point. It is open source and available to download from github (thanks to Chiel Kunkels).

CSS Desk – Created by Josh Pyles, this editor is for HTML and CSS only (no separate JavaScript). It has syntax highlighting, line numbers and realtime output. I like the fact that it allows you to easily save your edit out as a downloadable HTML file. You can save your snippet to a unique short URL for sharing. Minimal, but functional for CSS demos.

Liveweave – Created by Amit Sen, this tool requires you to have all your CSS and JavaScript in the HTML page (there is not separate panels like the other editors). It allows you to save your page as a downloadable HTML file which is handy. But for me, the killer feature (which most of the other editors don’t have) is auto-completion and code completion, a very useful addition (who can possibly remember all those CSS attributes and values?)

Cssizer – This tool (built by David Morrow) is also designed for HTML and CSS (not JavaScript) and has a limited feature set. However it does have syntax highlighting, realtime preview, and saving of snippets to a unique short URL (which get saved for you if you login using Twitter). You can also validate your code with an automated link to W3C. It is also open source and available to download from github.

pastebin.me – Created by Dale Harvey as a personal project, this tool is pretty bare-bones. A single editing panel with a non-realtime output panel. No syntax highlighting or features that the other editor have. It is available to download from github.

Html5Snippet – This is quite a slick editor with a number of saving and sharing features. I like the way you can download your code as separate files (.html .css .js) in a ZIP file. The editor also includes a huge list of predefined JavaScript frameworks and libraries. You can follow Html5Snippet on Twitter here.

Google Code Playground – This is similar to the HTML5 Rocks Playground, in that it is intended to demonstrate pre-written chunks of code (not as an editor for you to create your own and save) that you can tweak to see the results. The great thing about this is that it is chock-full of fantastic examples of accessing Google APIs, ranging from Google Translate and Google Calendar, through to Google Search, Maps and YouTube. If you are planning on using a Google API, it is worth checking here first to see if there is an example that will help. The link to the documentation is context sensitive, depending on what type of example you are viewing at the time.

TheCodePlayer – At the time of writing this site doesn’t allow you to create your own snippets and save them. But it does allow to play back the creation of their example HTML, CSS and JavaScript examples, which is very nice. It looks like in the future they are planning on opening the editor up for public use, to allow you to contribute your examples. I’d say ‘Keep an eye on this one’. Follow their Twitter stream here.

That pretty much wraps it up for now. I’m sure there are a bunch of other ones I’ve missed off this list (eg. Plunker), let me know in the comments if there is one I should take a look at. Enjoy!

HexoSearch – A Search Engine Dedicated to Actionscript

December 21st, 2009 by Adrian


HexoSearch – The World’s First Search Engine Dedicated to Actionscript

I know this has been around for quite a long time now, but I had kinda forgotten about it. It is a seach engine that is set-up specifically to search ActionScript related sites for your search term. This can be better than just using Google because it helps filter out all the non-actionscript content for you.

You can also add HexoSearch directly into your browser.

Version Checker

Have you ever wondered what version of the Adobe AIR Runtime you have installed on your computer? Well, if you have then you’ve probably found it difficult to find out. Luckily Jason Madsen has built a simple AIR App that will tell you. It does what it says on the tin. Very handy!

BTW, if you want to know what version of the Flash Player you have installed in your browser just visit www.playerversion.com to find out. Thanks Aral.
