Introduction to CSS (Cascading Style Sheets) in Web Designing

Web Designing Training in Chandigarh, Cascading Style Sheets (CSS) is a style sheet language used to describe the presentation of a document written in HTML or XML (including XML dialects such as SVG, MathML, or XHTML). CSS describes how elements should be rendered on screen, on paper, or in speech, or on other media.

CSS is one of the core languages of the open web and is standardized across Web browsers according to the W3C (World Wide Web Consortium). Previously, the development of various parts of CSS specification was done synchronously, which allowed the versioning of the latest recommendations. You might have heard about CSS1, CSS2.1, or even CSS3.

Benefits of using CSS

There are many benefits to using CSS, including:

  • Separation of concerns: CSS separates the content of a web page from its presentation. This makes it easier to maintain and update a web page, as you can change the presentation without affecting the content.
  • Consistency: CSS allows you to create consistent styles across your entire website. This makes your website look more professional and polished.
  • Accessibility: CSS can be used to make your website more accessible to people with disabilities. For example, you can use CSS to enlarge the font size of your text or to add alt text to images.
  • Performance: CSS can improve the performance of your website by reducing the amount of HTML code that needs to be downloaded. This is because CSS can be used to style multiple elements on a web page with a single CSS rule.

How CSS works

CSS works by applying styles to HTML elements. A CSS rule is made up of two parts: a selector and a declaration block. The selector specifies which HTML element the style should be applied to, and the declaration block specifies the style properties.

For example, the following CSS rule would apply a red font color to all <h1> elements:

CSS

h1 {
  color: red;
}

You can also use CSS to style individual elements on a web page. To do this, you need to give the element a unique identifier. For example, you could give an <h1> element the following identifier:

HTML

<h1 id="my-heading">This is my heading</h1>

You can then use the following CSS rule to style the heading:

CSS

#my-heading {
  color: blue;
}

  • Inline CSS: Inline CSS is added directly to the HTML element that you want to style. Inline CSS is the least specific type of CSS, and it will be overridden by internal and external CSS.
  • Internal CSS: Internal CSS is added to the <head> section of your HTML document. Internal CSS is more specific than inline CSS, and it will be overridden by external CSS.
