Modifying DOM Elements

Once we can grab DOM elements, we can modify them. There are several methods to change DOM elements. If we would like to set the attribute on an element…

let myElem = document.getElementById(‘elementId’); myElem.setAttribute(‘attributeName’,‘attributeValue’
); 

If we would like to add a class to an element…

let myElem = document.getElementById(‘elementId’); myElem.classList.add(‘className’); 

If we would like to change the style of an element…

let myElem = document.getElementById(‘elementId’); myElem.style.color = ‘#333’; 

Here we can use color names, RGB(a), hex codes and HSL(a).

We can even change the text content of an element…

let myElem = document.getElementById(‘elementId’); myElem.textContent = ‘Here is some new text!’; 

Happy Coding!

A Quick Tour of the Web Encoding API

Modern web apps live at the boundary between JavaScript strings and raw bytes. The Web Encoding API exists to make that boundary explicit and safe: it lets you encode a string into UTF‑8 bytes and decode bytes back into text. Importantly, these operations aren’t symmetrical—encoding targets UTF‑8, while decoding can interpret UTF‑8 and many legacy encodings. Alongside the synchronous TextEncoder and TextDecoder, the platform also provides stream-based variants for processing text incrementally as data arrives.

EditContext API: A New Foundation for Custom Web Editors

The experimental EditContext API gives developers a new foundation for building custom rich text editors by separating text input and selection from rendering. Instead of relying on contenteditable, you attach an EditContext to a focusable element and manage your own text model, selection state, and UI updates—while still receiving browser-grade events for typing, caret movement, and IME composition. This demo highlights the core event flow and why character bounds matter for accurate input UI, especially in custom-rendered editors.
