To edit HTML and CSS code you only need a simple plaintext editor, the rest depends on your skills and your creativity. However, you'll be more inspirated if you use the proper tools while you work. We know too that not everybody is able (or want) to pay for a license of a fancy code editor, that's when we love the Open Source. There are many free IDE's and code editor out there and you may want to know which may fit better to my requirements. To make it easier for you or your team to develop web applications, we have found some really good Integrated Development Environments for JavaScript, which provides you a convenient environment to code, edit, test, and debug web applications. RJ TextEd is a full featured text and source editor with Unicode support.

It is also a very powerful web (PHP, ASP, JavaScript, HTML and CSS) development editor. The functionality extends beyond text files and includes support for CSS/HTML editing with integrated CSS/HTML preview, spell checking, auto completion, HTML validation, templates and more. The program also has a dual pane file commander, as well as a (S)FTP client to upload your files. RJ TextEd is developed in Delphi XE6 from Embarcadero and is released as Freeware.

It supports the following features (and more): • Auto completion. • Code folding. • Column mode. • Multi edit and multi select • Document map • Annotation bar • Advanced sorting. • Handles both ASCII and binary files. • CSS and HTML wizards. Adobe pdf driver for mac. • Highlighting of colors in CSS/SASS/LESS.

It includes a web browser, email and newsgroup client, IRC chat client, and composer, the web page editor. One of the nice things about using SeaMonkey is that the browser is built-in, so testing is a breeze. Coda may be the best IDE for the Mac, and it's one of the few IDEs created with the sole intent of web development. Its concept of sites is pretty neat, and you can remotely edit files on almost any server.

Despite the dramatic shift toward simplification in software interfaces, the world of development tools continues to shrink our workspace with feature after feature in every release. Light Table is based on a very simple idea: we need a real work surface to code on, not just an editor and a project explorer. We need to be able to move things around, keep clutter down, and bring information to the foreground in the places we need it most. Here's what the default mode looks like. It is a standalone app, the fact that there's an instance of webkit as the UI layer is completely an implementation detail. It will be packaged like a normal app and it will run locally just like any other editor you're used to.

This means that it can run on virtually any platform and will support the big three (linux/mac/windows) out of the gate. Light table is based on a few guiding principles: • You should never have to look for documentation • Files are not the best representation of code, just a convenient serialization. • Editors can be anywhere and show you anything - not just text.

• Trying is encouraged - changes produce instantaneous results • We can shine some light on related bits of code Let's take a look at how these things manifest themselves in Light Table.
