Attributes

Basic Syntax

Attributes are specified only within the triangle brackets of the opening tag of an element. The syntax for defining an attribute is as follows:

Key Points:

• Attributes can be optional or required: Depending on the element, specific attributes may be required to function correctly, while others are optional and provide additional customization options;
• Attributes are enclosed in quotes: Attribute values are enclosed in either double quotes ("...") or single quotes ('...'). This helps to distinguish them from the element's name and aids in readability;
• Each tag has its own set of attributes: Different HTML elements support different attributes. Understanding the specific attributes applicable to each element is essential to utilize them effectively;
• Multiple attributes can be used: It is possible to include multiple attributes in a single element by separating them with a space. This allows for more extensive customization and control over the element's behavior.

Example Usage

Let's explore a few examples of HTML elements with attributes to understand how they impact the elements' behavior:

Line-by-line code explanation:

• Line 1: it creates a text box where users can type. The type="text" attribute specifies that this is a text input field, while placeholder="name" displays a hint inside the box with the word "name" to guide users;
• Line 2: it shows an image of a forest. The alt="Forest" attribute provides alternative text, so if the image doesn’t load, users will see "Forest" instead. The src="..." attribute defines the image's location on the web;
• Line 3: it creates a clickable link to Google. The target="_blank" attribute ensures that the link opens in a new tab, while href="..." specifies the destination URL.

Each attribute here adds specific behavior or functionality to the element, making your HTML content more interactive and user-friendly.

Note

We will further delve into the details of each element's attributes in this course. For now, it is crucial to comprehend the concept of attributes, their application, and the fact that each element possesses its unique set of attributes. These attributes play a significant role in altering the element's appearance, purpose, and functionality.

Sum up

HTML element typically consists of a tag, attributes, and content.

• Tag defines the element type (e.g., p, img, etc.);
• Attribute provides additional information about the element (e.g., src, alt, etc.);
• Content is anything between the opening and closing tags of the element.
