Intl.DurationFormat: Format Time Durations with Locale Support - Stop writing manual duration formatting code. Instead, leverage the new powerful Intl.DateTimeFormat API for internationalized time displays.

Let the stagger experiments begin - I proposed an idea to help remove a ton of boilerplate code from CSS and HTML while also making stagger effects easier on authors.

Introducing command and commandfor - Buttons are essential to making dynamic web applications. Buttons open menus, toggle actions, and submit forms. They provide the foundation of interactivity on the web.

How To Build Confidence In Your UX Work - UX initiatives are often seen as a disruption rather than a means to solving existing problems in an organization. In this post, we’ll explore...

Serve Static Assets with an Efficient Cache Policy - When visitors return to your website, you can make their experience lightning-fast by properly caching your static assets.

In Vue (and likely in other frameworks), there's an effective method for conditionally applying an inline CSS class. While it may seem counterintuitive at first, it delivers clean and reliable results.

<template>
  <div :class="{'undefined-image': isImageUndefined}" class="app-content">
    <!-- Your content here -->
  </div>
</template>

This approach dynamically applies the undefined-image class when isImageUndefined is true. If the condition is false, the class is omitted. While there are multiple ways to achieve this, the simplicity and clarity of this solution make it a standout option.
