CSS Basics Introduction
CSS, or Cascading Style Sheets, is a style sheet language used to define the presentation of a markup language such as HTML or XML. CSS allows you to control the layout, color, font, and other visual elements of a web page, allowing you to create a visually appealing and consistent design across multiple pages.
Here's a brief introduction to some key concepts in CSS:
1. Selectors: CSS uses selectors to target specific HTML elements and apply styles to them. For example, you might use the selector "h1" to target all of the <h1> elements on a page.
2. Properties: CSS properties are used to define the visual styles of the targeted HTML element. For example, you might use the "color" property to set the text color, or the "background-color" property to set the background color.
3. Values: CSS values are the specific settings for each property. For example, you might use the value "red" for the "color" property to make the text red.
4. Cascading: The term "cascading" in CSS refers to the way that styles are applied to HTML elements. If multiple CSS rules target the same element, the styles will be applied in a specific order of precedence.
5. Specificity: Specificity is a way of determining which CSS rule should take precedence when multiple rules target the same element. In general, a more specific rule will take precedence over a less specific rule.
To use CSS in your web pages, you can include a <style> element in the <head> section of your HTML document, or you can include an external CSS file using the <link> element. Then, you can write CSS rules using selectors, properties, and values to define the styles for your HTML elements.
Here's an example of a simple CSS rule:
Css Copy code;
h1 {
color: red;
}
This rule targets all <h1> elements on the page and sets the text color to red.
With CSS, you can create sophisticated layouts, apply styles to specific elements or groups of elements, and achieve a consistent look and feel across your website. There are many resources available online to help you learn more about CSS and its various features and capabilities.
