What is Lazy Loading?

Lazy Loading is a performance optimization technique that loads images as the user scrolls down the page, instead of during the initial page load.

On the browser side, the page loads faster because it’s not loading all the images right away.

On the tech side, it works by replacing the html image src attribute with a data-src placeholder – this prevents the image from loading in the standard html sequence.

Shopify Liquid Lesson: Auto Minifying CSS

2018-12-17T23:48:48+00:00July 27th, 2018|Performance Optimization, Tutorials|

CSS and Minification

CSS (Cascade Styling Sheets) are files that control the style of your website by connecting style properties to html elements.

Like this:

In Shopify, you’ll find CSS files in your theme Assets folder.

What is minification?

CSS are text files. Minification compresses the text by removing extra characters like spaces and comments, and combining common styles.

This makes the file size smaller. When your files are lighter they transfer faster, which helps your site load faster.

The Challenge

You want to compress your files, but you also want them to be readable so you can edit and make updates.

No worries, Shopify has a technique that compresses your human readable CSS files into minified files on the server.

In this article:

  1. What is a vector graphic
  2. Examples of vector (SVG) vs non-vector (JPG, PNG)
  3. How to make/use an SVG (vector graphic for websites)

What is a vector graphic?

Vectors are lightweight scalable digital art graphics, meaning they can be sized up without losing resolution or pixelating (as opposed to a jpg or png which gets blurry when you make it larger).

The art files are created using lines and math instead of individual pixels or bitmaps.

SVG is a type of vector graphic used for the web. SVG = Scalable Vector Graphic.

Here’s why SVG’s are awesome:

  • The image is sharper
  • They’re usually lighter (faster loading)
  • They can scale to any size without becoming blurry or losing resolution
