Magento keeps searching for complementary acquisitions as part of their investment strategy. To provide merchants with a simple and functional tool to manage their webstore content, Magento acquired the well-known Bluefoot CMS & Page Builder module. In this article we are going to review its key features and show you an example of a retailer, who used this module to add unique and creative content to his webstore pages.
Today we’d like to represent a sort of tutorial that describes how to add CSS files in Magento. Hope you’ll find the article useful and gain new skills while dealing with CSS files.
How to add CSS
CSS files are usually located at skin/frontend/our_package/our_theme/css. In fact, there are 4 ways to add CSS files to HTML:
Linking to a separate CSS file
<link rel="stylesheet" type="text/css"
href="mystyles.css" media="screen" />
Embedding CSS into the HTML
<style media="screen" type="text/css">
Add style rules here:
Adding inline CSS to HTML tags
<h2 style="color:red; background:black;">Red
heading with a black background</h2>
Importing a CSS file from within CSS
In order to merge CSS files into single HTML, you need to go to the admin panel and select System – Configuration
On the left menu, you need to select Developer, then open CSS Settings and change Merge CSS File into Yes, click Save Config and clear cache.
Note. The styles break in case there are inline resources
url('data:...') in the code.
First off, you need to create the browser list (every website has its own visitors who may use different browsers, so with the help of analytics you can define these browsers and form your own list of supported browsers).
Using the plugin postcss-remove-prefixes, you should remove pesky vendor prefixes. So it makes sure any CSS code will be optimized in the next step according to the browser list that has already been formed.
Add just specific prefixes for CSS using autoprefixer. Do not forget to define the list of supported browsers created earlier.
It’s necessary to perform minification. Actually, there are many different minificators you can use.
Other CSS skills
There are following types of selectors in CSS:
- Adjacent Sibling
As for the rules of priority (specificity), they are usually represented by weight like that:
- Attribute = 1000
- ID = 100
- Class = 10
- Elements = 1
When two selectors have the same weight, the browser will render the last
declared one on the styles sheet, what “cascading” means.
There are general methods of speed optimization related to CSS:
– Compress CSS
– Combine CSS files
– Split styles according to Media Query Breakpoints
– Remove all unnecessary vendor prefixes
