Building websites is a multifaceted process that necessitates a range of skills and technologies. Notably, HTML and CSS serve as the fundamental technologies underpinning websites. When skillfully combined, HTML and CSS empower developers to craft visually captivating, well-structured websites, enhancing user engagement.

Explore the fundamentals of CSS, covering its syntax, features, benefits, and more below.听

What does CSS stand for?

CSS is an acronym for Cascading Style Sheets. In web development, a style sheet refers to a document that includes guidelines and directives governing the presentation of elements within a web page. CSS adjusts the font, size, or decorative flourishes like animations or images.听

Every web browser comes equipped with a default style sheet. However, most web pages feature custom CSS styles configured by web designers, which override the default CSS settings. The cascading nature of CSS ensures that the last defined style sheet takes precedence.听

The origin of CSS

The concept of styling a website emerged as early as 1994. While no single individual invented CSS, H氓kon Wium Lie, a Norwegian web pioneer and computer scientist, proposed the original idea.

Soon afterward, Bert Bos, a renowned Dutch computer scientist known for his contributions to the Argo browser, partnered with Lie to develop the CSS specification. Lie and Bos authored the first official CSS specification, published by the World Wide Web Consortium (W3C) in 1996.听

How does CSS work?听

If hypertext markup language (HTML) is the skeleton of a book, outlining the chapters, sections, and content, then CSS serves as the book鈥檚 cover design and typography, enticing readers to pick up and explore the book.

More technically, HTML elements represent different components on a web page, such as a paragraph or a heading. For example, this is an HTML tag:

<p>This is a paragraph</p>听

Remember, the paragraph on its own lacks styling. The following CSS code, however, can style this paragraph:听

p听 {听 color: purple;听 font-weight: bold;听 }

In the CSS mentioned above, 鈥減鈥� acts as the selector, specifying that the styling applies to all HTML paragraphs. The code within the curly brackets forms the declaration, which includes properties (color and font) and their corresponding values (purple and bold) that the selector will inherit.听

Similarly, altering the values can achieve various styles. For example, a property like 鈥渂ackground-color鈥� can have values like 鈥渞ed鈥� or 鈥渂lue, 鈥渂ackground-position鈥� can have values like 鈥渢op鈥� or 鈥渂ottom,鈥� and 鈥渢ext-align鈥� can have values like 鈥渃enter,鈥� 鈥渞ight,鈥� or 鈥渓eft.鈥�

Did you know? US government websites use 鈥渦sa鈥� as a prefix for CSS selectors (e.g., .usa-button) to prevent possible conflicts with styles not associated with the US Web Design System [].

Types of CSS

A web designer may harness one of three CSS types to style and customize a website: inline, embedded (internal), or external. Let鈥檚 explore each of them in detail below.

Inline CSS

Inline CSS applies styles to a single HTML element and defines them within its style attribute. This approach is useful for rapidly previewing, testing, or addressing issues with web pages. However, excessive inline CSS can cause the HTML structure to become disorderly.

Embedded CSS听

Embedded or internal CSS involves placing the CSS code directly within the HTML file. This is useful when applying a unique style to a specific HTML page. However, using embedded CSS for multiple pages can be tedious, as the CSS style must be added individually to each page.

External CSS

External CSS is particularly useful for styling large websites. To apply external CSS, web pages must connect to an external.css file. The approach enables web designers or developers to maintain a consistent style across all pages. Then again, it鈥檚 important to note that using multiple CSS files may impact website loading time.听

In summary, the use of inline CSS applies to individual elements, while embedded CSS pertains to specific pages, and external CSS serves for styling an entire website. Choosing the right CSS type depends on the project鈥檚 unique requirements and scope, considering the advantages and disadvantages of each approach in website styling.

Pros and cons of using CSS

Every programming language has its strengths and weaknesses. Let鈥檚 look at some notable advantages and disadvantages of using CSS in web development:

Advantages

• Support for simultaneous application of styles across multiple web pages

• CSS鈥� minimal code enhances website loading speed, boosting search engine rankings

• Streamlining site upkeep, CSS allows changes to website design elements without altering the underlying HTML code.

Disadvantages

• Choosing the right CSS type can be confusing

• CSS code fragmentation across web browsers may cause compatibility issues
