Interacting with a webpage using JavaScript starts with one essential task—finding the right elements in the Document Object Model (DOM). The DOM is a structured representation of an HTML document that allows JavaScript to access and manipulate its elements dynamically. One of the most flexible and powerful ways to locate elements is through the querySelector […]

Forms are the bridge between users and web pages—allowing people to enter data, choose options, and trigger actions. In HTML, form elements contain various elements, such as text inputs, checkboxes, radio buttons, dropdowns, and buttons. JavaScript interacts with these elements to read input, adjust defaults, or react to changes made by the user. Accessing form

Interacting with HTML using JavaScript becomes truly powerful when you tap into the Document Object Model (DOM). The DOM represents the entire structure of your web page as a tree of nodes, where every element—like a paragraph, div, image, or list—is a branch that can be accessed and manipulated. JavaScript lets you grab these elements

In HTML, a class is a way to group elements together that share a common purpose or style. Unlike IDs, which must be unique, many elements on a page can share the same class name. This makes classes perfect for applying the same behavior or appearance to multiple elements at once — such as styling

The Document Object Model (DOM) is like a living map of all the elements on a webpage. It lets JavaScript talk to the page, find elements, and change them in real time. Every HTML element can have a unique identifier called an ID. Think of an ID as the element’s personal name tag — no

In modern web development, controlling what appears inside an element—be it a heading, a paragraph, or a button—is a key part of how we build interfaces. This inner content is what users read, click, or interact with, and JavaScript gives us direct tools to read and change this content on the fly. When we talk

In HTML, classes are attributes assigned to elements that allow developers to group elements for styling or scripting. A class can be thought of as a label that marks one or more elements, telling the browser or JavaScript what styles or behaviors apply to them. For example, if you want several buttons to look the

In HTML, data-* attributes are a way to store custom data on elements. These attributes don’t affect how the page looks or behaves directly, but they allow developers to store extra information in the HTML, such as user IDs, product types, language preferences, or access levels. This makes them ideal for use with JavaScript when

HTML elements are more than just tags — they carry extra information through attributes. Attributes define how an element behaves or appears. You’ve seen them everywhere: Here’s what each attribute does: Attributes like these give meaning to elements and guide how they behave in the browser. With JavaScript, we can go a step further —

The JavaScript bind() method creates a new function that has its this keyword set to a specific value. This helps control what this refers to when the function runs. The goal of this article is to show you how to use the bind() method to fix the value of this in functions. This is especially
