Cascading Style Sheets, or CSS for short, are used to apply styles on our website. Using CSS makes it easier for us to make our website look great. It separates the structure (which the HTML document is made of) from the presentation, which is what the user sees and interacts with.
Why we need CSS for page display
Having a different and creative style has become a must have property for a website, as it makes the website fun to interact with, instead of a plain and dull looking website which can be made using only HTML.
There are three ways to apply CSS to our website:
-
Inline Styles− When we apply styles to each individual HTML tag, this is called inline style.
An example of inline styling in CSS is given below.
<h1 id="This-is-an-example-of-using-inline-styling-in-CSS"> This is an example of using inline styling in CSS </h1>
Embedded styling − When the style tag is nested inside the head tag, making it such that the CSS seems embedded inside an HTML file. Then it is referred to as Embedded styling.
Example
<!DOCTYPE html>
<html lang="en">
<head>
<title>Embedded Styling</title>
<style>
h1 {
color: aquamarine;
}
</style>
</head>
<body>
<h1 id="This-is-an-example-of-embedded-styling-being-used-in-HTML">This is an example of embedded styling being used in HTML.</h1>
</body>
</html>
External Styles - This is the most recommended way of using CSS, it separates the CSS from the HTML by using a .CSS file that contains all the styling information and links it to the HTML document. We can attach multiple CSS files using this styling method.
An example of using external CSS styles is shown below.
<head> <link rel=”stylesheet” href=”style.css”> </head>
What came before CSS?
Before the advent of CSS, HTML introduced tags like the or color attribute for styling purposes. However, the process of adding font and color information to each page of a large website is time-consuming and expensive. That's why CSS was introduced, which eliminated HTML formatting using these weird tags.
The introduction of CSS separated the structure and styling, where HTML was used for structuring the web page while CSS focused on incorporating style and presentation in the webpage.
Advantages and ease of maintenance of CSS
As we already know, CSS provides us with simple formatting options to improve the presentation of web pages. But that's not all. The main advantages of using CSS are listed below.
For simple websites, we can use CSS inside the HTML document, while for a large website we can create separate CSS files. This provides us the choice as to which form of CSS should we use depending on our website.
It has better community support.
In the past we had to specify fonts, colors, etc. for each web page separately, but the introduction of CSS has made this complex and lengthy process simpler.
We can save time by making error detection and correction simple by using CSS files rather than integrating them into the document itself. Updating one file updates all style information on our website.
It makes the process of loading the web page fast as we are only applying rules and styles to each tag only once as compared to HTML formatting where we had to use tags like
It also provides easier maintenance because it makes the formatting global and can be modified by modifying the global formatting style. We no longer need to modify formatting and styling for each element individually on each page.
We can use CSS to adapt to multiple devices because it is compatible with almost all possible devices. This multi-device compatibility gives it a huge advantage in modern computing.
Due to its simplicity and popularity, it has now become a skill that is required for every web developer. Designing a website creatively is what makes your website stand out from others and CSS is the language that provides us with the ability to do so.
It completely transforms a dull and bland website into a stylish and attractive website that grabs the user's attention and makes their interaction with the website fun, This is not possible using HTML alone.
Increased user experience by giving the ability create wonderful UI which helps the users to navigate the website easily by eliminating the complexity of the rigid design of HTML.
It is needed by every web developer to give life to their designs.
Platform independence is consistently provided by the Script, which also works with the most recent browsers.
The term "cascading" implies that we can employ multiple styles, with local styles predominating. The local style assignment might take the place of the global style declaration.
These advantages are enough to explain the ease of maintenance that CSS provides. Along with these, we can also use CSS to create a responsive website(using media queries), which is an emerging requirement for modern websites. Without CSS, web creation is not feasible. CSS may initially seem challenging, but after a few ideas are understood, CSS will feel incredibly straightforward and uncomplicated.
Conclusion
In short, CSS is a powerful tool for achieving maintainable websites. This allows developers to make changes quickly and easily without having to rewrite large amounts of code or worry about compatibility issues. Additionally, CSS provides the ability to reuse styles across multiple pages, reducing development and maintenance time and ensuring website consistency. Overall, CSS is a powerful and inexpensive way to make your website easier to maintain in the long run.
