X-Parallax: New HTML5 Web Component

A couple of days ago I blogged about an experiment in the creation of a purely CSS3-driven parallax effect, and ever since I started thinking of wrapping it as a custom HTML5 Web Component to avoid the hassle of class names and rules in setting the slide images or background color.

As a whole, I am very happy with the result, called X-Parallax. It is easy to configure, fully responsive and very fast. Below are a few screenshots, but if you want you may want to jump straight to the demo (acting also as a tutorial of how to use it) and download the code.


<acidjs-xparallax nav="top" animationspeed="2000" defaultslide="0">
    <acidjs-xparallax-slide label="X-Parallax" background="images/roots.jpg">
            <!-- slide content -->
    <acidjs-xparallax-slide label="Download" background="images/sea.jpg">
            <!-- slide content -->
    <acidjs-xparallax-slide label="Installation" valign="middle" background="images/flowers.jpg">
            <!-- slide content -->
    <acidjs-xparallax-slide align="left" valign="top" label="Customization" background="images/glass.jpg">
            <!-- slide content -->
    <acidjs-xparallax-slide label="HTML5 Web Components" align="left" background="images/broken.jpg">
            <!-- slide content -->

Syntax Highlighter HTML5 Web Component Based on Lea Verou’s Prism.JS

AcidJs.XHilite is a syntax highlighter HTML5 Web Component, based on Lea Verou‘s Prism.JS and wrapped as a custom tag with support for multiple languages and both declarative and async loading of the code to be highlighted.


<acidjs-xhilite language="javascript" height="200" width="400">
function sayHi() {
    return "Hello, World"!;

Recently I my HTML5, CSS3 and JavaScript Experiments website received a major facelift and as a next step and I am planning to replace the syntax highlighter I am currently using with AcidJs.XHilite.

HTML Attributes of the Tag

Any native HTML attribute (id, class, data-*, style, etc.) is supported, plus the component-specific:

  • language – The language to highlight, for example language="javascript". Default: "markup" (usable with HTML, SVG, XML, etc.). Check for a complete list of supported languages.
  • width – Optional width in pixels of the code block, for example: width="600".
  • height – Optional height in pixels of the code block, for example: height="200".
  • src – Instead of adding the code to highlight in the tag, you can specify path to the file which content needs to be highlighted, for example: src="example.js"

JavaScript Methods of the Tag

Native JavaScript methods (document.getElementById, document.querySelector, etc. as well as their jQuery or other libraries aliases).

X-NotificationsBar: HTML5 Web Component

Just finished my new endeavour in the amazing world of HTML5 Web Components, called X-NotificationsBar and based on an earlier CSS3-only driven solution. Here’s how to use it, after you check the demo and eventually download it:

<acidjs-x-notifications-bar bgcolor="#016fba" expanded="true" message="random" loop="5000">
        HTML5 Web Components enable truly encapsulated and reusable components for the web.

The <acidjs-x-notifications-bar></acidjs-x-notifications-bar> Tag Attributes:

  • bgcolor – Optional background color. Default value: “#e34c26”.
  • expanded – Boolean, optional. Default: “true”.
  • message – Zero-based index or “random”. “0” means that the content of the first <acidjs-x-notifications-bar-message> will be set. If “random” is set, a random message will be displayed. Default: “0”
  • loop – Optional timeout in milliseconds for looping messages. Default null.

The <acidjs-x-notifications-bar-message></acidjs-x-notifications-bar-message> Tag:

It should be used to set messages to the notifications bar, one message at a time. The tag does not support any attributes and accepts any HTML.

Have fun and enjoy the weekend!

X-Checkbox – Custom HTML5 Web Component

People who follow this blog (cheers, mates!) and my fellow co-workers know that I am interested in the form control styling, and especially that of check boxes and radio buttons. Over the years I have come up with a number of different solutions, but finally I found the time to start experimenting with the new and exciting world of the HTML5 Web Components. This is my first attempt to create a custom web component – a custom check box, built on top of Mozilla’s X-Tag library. The reason I did not use Google Polymer is just because I started playing with X-Tags, but certainly in the near future I will utilize Polymer.

So here it is – as easy as <acidjs-xcheckbox></acidjs-xcheckbox>, supporting native getters, setters and native properties (checked, disabled, class, etc.) as well as any other custom attributes, form submission without additional check box manipulation, keyboard events plus a couple of additional methods for toggling the enabled and checked states.

Since Shadow DOM is not consistent across browsers yet, the gory guts of the component will reveal a simple check box, wrapped in a label. The look and feel has been achieved with CSS3. Tested on Firefox and Chrome, but supposedly should work on other modern browsers plus IE11.


Have nice weekend and greetings from sunny Malta!

My New Home Studio in Malta

I recently left Germany relocating to the island of Malta, and a couple of weeks later I was finally able to deploy my new home studio with a new addition – an amazing custom-made 2 x 12 guitar cabinet with Celestion V30 speakers, built for my by Paul Gough of Zilla Cabs (cheers, Paul – for all the hard work, patience and killer quality).

Here are a few photos of the studio. Hopefully I find more time for playing the guitar in the teeth of my main job as a front-end developer. In case you are interested, here’s a detailed rundown of my rig, and on this page you’ll find a lot more photos and specs of my guitars and gear.
