HTML Attributes | Understanding the Key Modifiers
In HTML, attributes provide additional information about an element. They are used to modify the behavior or appearance of HTML elements. Each attribute is placed within the opening tag of an element and consists of a name and a value.
Types of HTML Attributes:
- Global Attributes: Attributes that can be used with any HTML element, such as `id`, `class`, and `style`.
- Specific Attributes: Attributes that apply only to certain elements, such as `src` for the `
` tag or `href` for the `` tag.
How HTML Attributes Work:
Basic Structure of an Attribute
1. An attribute is written in the opening tag of an element.2. The attribute name is followed by an equal sign and the attribute value in quotes.
3. Multiple attributes can be added to a single element, separated by spaces.
Common HTML Attributes:
- id: Provides a unique identifier for an element. Used for styling or linking to a specific part of the page.
- class: Assigns one or more class names to an element. Often used for styling or JavaScript manipulation.
- style: Specifies inline CSS styles for an element.
- src: Specifies the URL of an image or other media file. Used with the <img>, <audio>, and <video> tags.
- href: Specifies the URL of a link. Used with the <a> tag to create hyperlinks.
- alt: Provides alternative text for an image if it cannot be displayed. Used with the <img> tag.
- type: Specifies the type of an input element. Used with the <input> tag to define types like text, password, and submit.
- value: Defines the value of an input element. Used with form elements like <input> and <option>.
