Responsive Images In WordPress With Art Direction

Images that are inserted within the text of a post automatically get the responsive treatment, while images that are handled by the theme or plugins — like featured images and image galleries — can be coded by developers using the new responsive image functions and filters.

Ways To Reduce Content Shifting On Page Load

Optimizing Critical-Path Performance With Express Server And Handlebars

Recently, I’ve been working on an isomorphic React website. This website was developed using React, running on an Express server.

This article contains my notes about installing and configuring a critical-path performance optimization using Express and Handlebars. Throughout this article, I’ll be using Node.js and Express. Familiarity with them will help you understand the examples.

Five Simple Steps To Test Your Varnish Cache Deployment Using Varnishtest

Varnish Cache is an open source HTTP accelerator that is used for speeding up the content delivery of the world’s top content-heavy dynamic websites. However, the performance or speed a newcomer to Varnish Cache can expect from its deployment can be quite nebulous.

Managing Mobile Performance Optimization

You can’t underestimate the importance of consistent, high-quality web design across devices of all shapes and sizes. Responsive web design is the way forward — but it’s often linked to performance issues.

Managing Mobile Performance Optimization

The best designs balance aesthetics and performance by working with mobile in mind from the start. From setting strict performance budgets to implementing client- and server-side optimization techniques, I’ll share the current mobile performance optimization processes we use at Cyber-Duck.

Preload: What is it good for?

A few weeks ago, I shipped preload support in Chrome Canary, and barring unexpected bugs it will hit Chrome stable in mid-April. But what is that preload thing? What does it do? And how can it help you?

Turn Your AMP Up To 11: Everything You Need To Know About Google’s Accelerated Mobile Pages

In May of 2015, Facebook unveiled its new in-app publishing platform, Instant Articles.
