7 Excellent Websites for Learning Sass
Using Sass makes your web design projects much easier to build, scale and maintain.
Taking the time to explore and learn Sass will yield many benefits. The Sass community is passionately helpful, so there’s no shortage of Sass tutorials, articles and guides on the Web.
In this post, allow me to share my list of favorite sites for learning Sass with you.
The Sass Way
This site publishes excellent Sass tutorials and guides. Their tutorials/guides are divided into beginner, intermediate and advanced categories, which makes it easy to find content that’s appropriate to your interests. The Sass Way also covers news about Sass.
Sass (SitePoint)
I’ve had the awesome opportunity to write for SitePoint. As someone who’s seen SitePoint from behind the scenes, let me tell you, the editors over there take Sass seriously. Sass is one of the most popular topics covered on SitePoint. In the last couple of months, they’ve posted sixteen or so articles and tutorials related to Sass. That’s more Sass content than sites that are exclusively dedicated to covering just Sass.
Sass Tutorials (Level Up Tutorials)
Level Up Tutorials has a great series of tutorial videos on Sass. The tutorial series is up on YouTube. The tutorial series starts off with the fundamentals, walking the learner through the installation of Sass, and then progresses in difficulty until all the key Sass features have been covered.
Sass break
This is a blog by David Conner and Guil Hernandez that they’ve dedicated to the Sass community. Their blog posts embrace a wide array of Sass subjects: Ruby Sass vs. LibSass, media query mixins and more.
Sass News
Sass News is an email newsletter on — You guessed it! — Sass news and links. This newsletter regularly shares links to Sass tutorials, guides, articles and demos. Check out the Sass News archives to find all the links they’ve posted so far.
Sass (Tuts+ Code) and Sass (Tuts+ Web Design)
I’m a huge fan of the Tuts+ network of websites — they continually put out top-notch tutorials. As for Sass tutorials and guides specifically, you’ll find plenty on Tuts+ Code and Tuts+ Web Design.
Official Sass Website
When it comes to learning Sass, it’s hard to beat the official Sass website. Folks wishing to learn Sass will probably hit up this site first. The site’s got content for beginners as well as advanced Sass users. Beginners should start at the Sass installation guide. Intermediate and advanced Sass users will probably want to jump straight to the docs.
Use Sass Today!
If you’ve never used Sass before, check out my tutorial: Use Sass Within Minutes.
In the tutorial, I’ll walk you through the steps for setting up Sass using a neat app called Prepros. The tutorial will help you build your first Sass project.

Understand Overriding in Magento: Controllers
In the third and last article of this Magento overriding series, I'll explain how to override core controller files. In the previous two articles of this series, we discussed overriding core files for blocks and models by creating a custom module. In this tutorial, we'll look at overriding core controller files.
Why Overriding Controllers?
In Magento, the controller is responsible for handling incoming requests, and it's a backbone of the Magento routing implementation. To handle probably every request in Magento, the controller defines different actions in the form of controller class methods. The controller action method includes related application logic which interacts with views and models to prepare the output of that particular page. Sometimes, you need to alter the flow of controller execution to inject custom code or change the core code.
As I said in the previous tutorial, it's never recommended to change core files directly, as it makes upgrading Magento really difficult. To avoid this, we should follow the standard way of making desired changes to core files: we should either use event observers or override core files with our custom module files. We'll discuss the overriding feature today.
In this tutorial, we'll make a custom module to understand how controller overriding works in Magento. In this custom module, we'll see how to override a "Product" controller class of the core "Catalog" module. Overriding works by setting up certain XML tags as per the conventions of Magento.
I assume that you're familiar with the basic module creation process in Magento. If not, you can refer to this article on custom module creation.
A Glance at the Setup
Here's the list of files required for the desired setup:
app/etc/modules/Envato_All.xml: It's a file used to enable our custom module.app/code/local/Envato/Catalog/etc/config.xml: It's a module configuration file in which we'll set up controller class overriding using certain tags as per the Magento conventions.app/code/local/Envato/Catalog/controllers/ProductController.php: It's a custom controller class file which we'll use to override the core "Product" controller class.
Creating Files and Folders: Custom Module
First, we need to create a module enabler file. Create a file "app/etc/modules/Envato_All.xml" and paste the following contents in that file. We've used Envato as our module namespace and Catalog as our module name. It'll enable our "Catalog" module by default.
<?xml version="1.0"?>
<config>
<modules>
<Envato_Catalog>
<active>true</active>
<codePool>local</codePool>
</Envato_Catalog>
</modules>
</config>
Next, we need to create a module configuration file. Create "app/code/local/Envato/Catalog/etc/config.xml" and paste the following contents in that file.
<?xml version="1.0"?>
<config>
<modules>
<Envato_Catalog>
<version>1.0</version>
</Envato_Catalog>
</modules>
<frontend>
<routers>
<catalog>
<args>
<modules>
<Envato_Catalog before="Mage_Catalog">Envato_Catalog</Envato_Catalog>
</modules>
</args>
</catalog>
</routers>
</frontend>
</config>
First, we've defined a module version number using the <version> tag. The <catalog> tag is the front controller router name of the "Catalog" core module. It informs the routing system that we want to override the controllers of the "Catalog" module.
Finally, the <Envato_Catalog before="Mage_Catalog">Envato_Catalog</Envato_Catalog> tag is used to inform the Magento routing system that it should load your custom module's controller files if available. Of course, it'll load the core files of the "Catalog" module if it isn't able to find them under your module.
Finally, the only remaining thing is to define a controller class Envato_Catalog_ProductController. Let's create a controller file "app/code/local/Envato/Catalog/controllers/ProductController.php" and paste the following contents in that file.
<?php
/**
* Product controller
*
* @category Envato
* @package Envato_Catalog
*/
require_once 'Mage/Catalog/controllers/ProductController.php';
class Envato_Catalog_ProductController extends Mage_Catalog_ProductController
{
/**
* Product view action
*/
public function viewAction()
{
// Include your custom code here!
// Get initial data from request
$categoryId = (int) $this->getRequest()->getParam('category', false);
$productId = (int) $this->getRequest()->getParam('id');
$specifyOptions = $this->getRequest()->getParam('options');
// Prepare helper and params
$viewHelper = Mage::helper('catalog/product_view');
$params = new Varien_Object();
$params->setCategoryId($categoryId);
$params->setSpecifyOptions($specifyOptions);
// Render page
try {
$viewHelper->prepareAndRender($productId, $this, $params);
} catch (Exception $e) {
if ($e->getCode() == $viewHelper->ERR_NO_PRODUCT_LOADED) {
if (isset($_GET['store']) && !$this->getResponse()->isRedirect()) {
$this->_redirect('');
} elseif (!$this->getResponse()->isRedirect()) {
$this->_forward('noRoute');
}
} else {
Mage::logException($e);
$this->_forward('noRoute');
}
}
}
}
We've defined an Envato_Catalog_ProductController class which extends the core Mage_Catalog_ProductController controller class of the Catalog module. The important thing to note here is that we've included the core controller file "Mage/Catalog/controllers/ProductController.php" before the class definition as Magento won't include it automatically.
In the above example, we've overridden the viewAction method of the Mage_Catalog_ProductController class. It means that whenever a product detail page is viewed in the front-end, it'll call the viewAction method defined in your custom controller class. So you can modify the code defined in that method as per your requirements.
Conclusion
So today, we learned how to override the core controller files in Magento using a custom module. I hope you've enjoyed this series and learned something useful which you can implement in your code! Share your queries and suggestions using the feed below!

jQuery Bootstrap MaxLength for Form Inputs
Bootstrap-Maxlength a jQuery plugin integrates by default with Twitter bootstrap using badges to display the maximum lenght of the field where the user is inserting text. Uses the HTML5 attribute “maxlength” to work.
The indicator badge shows up on focusing on the element, and disappears when the focus is lost.
