Useful HTML-, CSS- and JavaScript Tools and Libraries


Front-end development is a tricky beast. It’s not difficult to learn, but it’s quite difficult to master. There are just too many things that need to be considered; too many tweaks that might be necessary here and there; too many details to make everything just right. Luckily, developers and designers out there keep releasing useful tools and resources for all of us to learn, improve our skills and just get better at what we do. Such tools are valuable and helpful because they save our time, automate mundane tasks and hence help us focus on more important things.

Here at Smashing Magazine, we’re continuously searching for time-saving, useful HTML-, CSS- and JavaScript-resources for our readers, to make the search of these ever-growing tools easier. We hope that these tools will help you improve your skills as well as your professional workflow. A sincere thanks to all designers and developers who are featured in this round-up. We respect and appreciate your contributions to the design community.

HTML and CSS Tools Link

HTML Email Boilerplate
This website and its sample code creates a template of sorts, absent of design or layout, that will help you avoid some of the major rendering problems with the most common email clients out there. It also provides some helpful examples and snippets that will keep your email design rendering as true-to-form as possible.

This tool reloads the style sheet (not the HTML) of a page in all browsers, and it can even be configured to reload a page automatically in multiple browsers at the same time. The tool doesn’t host your website but rather runs your website’s own local server. To use it, you just need to install NodeJS and npm.

Vogue - Auto-reload stylesheets whenever CSS files are saved

LiveReload applies CSS/JS changes to Safari or Chrome without reloading the page and reloads the page automatically once the HTML changes. Alternatively, take a look at Live.js, a library that makes sure that you’re always looking at the latest version of the page you’re working on, whether you are writing HTML, CSS or JavaScript.

inuit.css—cooler than a polar bear’s toenails…

This application merges multiple images into one and generates CSS positioning for the corresponding slices; by reducing the amount of images and better utilizing the connection, CSS spritemapping can reduce your website’s loading time.


Normalize.css takes a slightly different approach to CSS resets. Rather than eliminating all browser defaults, Jonathan Neal and Nicolas Gallagher have taken the time to research how different browsers handle different bits of code and then kept the defaults that are useful. It saves you time as a designer, while also providing consistent results.

Normalize.css: A New Kind of CSS Reset

Zen Coding
Zen Coding is an editor plugin for high-speed coding and editing. The core of this plugin is a powerful abbreviation engine which allows you to expand expressions (similar to CSS selectors) into HTML code.

ASCII Pronunciation Rules for Programmers
Most programmers would recognize ASCII characters on a website and know how to use them in their own work. But how many know what to call all those characters? This article gives a pretty thorough rundown of common and not-so-common names for ASCII characters. It’s a useful guide if you’re ever at a loss when listening to another programmer speak about coding.

ASCII Character Pronunciation Rules

Weave Silk
Is your desktop, motivation or even design work in need of something fresh, swirly and remarkable? Just weave some Silk! Yuri Vishnevsky created this experimental, magical interactive gimmick. You can spend minutes playing around with this little technique, based upon HTML5 Canvas: no Flash in use.


No, this has nothing to do with CSS, HTML or JavaScript, but it is just remarkable. On her photography blog, Jamie Beck presents scenes from around the world, memorable events, food, people and small personal universes. The interesting part is that her photos are animated (hence the name); they come to life using good old animated GIFs. Pay a visit to the article Positioning an animated gif over a jpg image. His short tutorial explains how to save on bytes when putting GIFs and JPEGs together, without losing too much quality.

    This is an exemplary post about how helpful Smashing Magazine is for designers and front-end developers, Its strange but I haven’t used more than one or two of these services in past, I have my own set of css and html templates that I use when starting a new project.
    I am amazed to see some of these resources which can be extremely helpful to me.
    Table styler, list creator, layer styler are absolutely awesome.
    I still have to code my first HTML5 website, I’m lagging behind but HTML5 Boiler Plate will definitely be helpful.

    Anyway, Big Thanks SM.

    Please excuse the blatant self promotion, but I’ve been working on something that others may find useful:

    It’s a tool that allows you to try different font combinations quickly – one for header, one for paragraph. It uses Google Web Fonts, plus some common system fonts.

    [If others do find it useful, or have any good ideas on how to improve it, I would love to hear it!]
