Right‑sizing experiences with the Device Memory API
Use the Device Memory API to bucket users by RAM and serve right‑sized images and effects. It’s a coarse, privacy‑friendly hint for progressive enhancement.
Each of us relies on some sort of technology to improve our lives and the lives of others.
Web technology can be an amazing tool to improve businesses, quality of life and bring hope to those that otherwise may not receive it if it weren’t for a technological advance.
This is the reason that the Webolution Designs tagline is “We all want to change the world”.
Use the Device Memory API to bucket users by RAM and serve right‑sized images and effects. It’s a coarse, privacy‑friendly hint for progressive enhancement.
The Document Object Model (DOM) is the browser’s in-memory representation of your HTML, letting JavaScript select elements (querySelector), listen to events (addEventListener), update content (textContent), toggle styles (classList), and create/insert nodes (createElement, insertAdjacentElement). With it, a button can change a box’s text, toggle a highlight class, set a data attribute, or insert a new paragraph right after the box—no page reload required—illustrating the simple flow: select, listen, update.
The Credential Management API lets your site securely store and retrieve user credentials through the browser’s built‑in manager—no brittle autofill hacks required. In our demo, a successful login stores a PasswordCredential, and a single click later retrieves and auto-fills it for returning users. It’s a progressive enhancement: your form still works everywhere, but supported browsers deliver a faster, lower-friction sign-in. Pair it with proper autocomplete attributes today, and plan for WebAuthn/passkeys to level up tomorrow.
