使用 CSS 进行维护

CSS, widely known as Cascading Style Sheets, is used to style elements created using HTML tags and is responsible for the look and feel of a web page. We can use CSS to change the color of the text, change the background, add any image or create space between the text. We can create multiple ways to display a single piece of content.

In this article, we will explain the ease of maintainability of CSS and the advantages of CSS.

Advantages of CSS

The following are the advantages of using CSS -

save time

When we write CSS code, we can use it on multiple other elements in HTML because the code is reusable. We can apply a style to one element and then apply it to multiple web pages.

<style>
   .display {
      font-family: Arial;
      font-size: 25px;
   }
</style>

By looking at the code above, you can see how little code is used. And because the code is shorter, it can be compiled quickly, saving a lot of time.

Less code

The CSS code written to style elements on a web page can be used in multiple other places because we use classes, and maintenance is also easier with less code since bandwidth is less consumed.

CSS is easy to maintain

CSS styles can be defined globally or declared in a public location, and can be simply changed on any element. Let's say we have a website and we use the same style for some elements and different styles for other elements. When we want to change the style of these elements, we can easily do it by changing the style class. We can use property inheritance to use multiple stylesheets in HTML elements.

In the code below, by changing the class, we can change the style of the element.

<style>
   .display {
      font:12px Arial
   }
</style>

Comply with network standards

The HTML elements used nowadays are gradually depreciating, so it is recommended to use CSS and HTML elements to style the website in order to make the HTML elements compatible with current and future browsers.

Provide independent platform

CSS provides a platform independent hence can support various browsers and the website can be loaded easily without any errors.

Multiple ways to define multiple styles

The function of CSS is "cascading" as its name suggests, indicating that we can use multiple styles on a single element. We can override global styles and declare local styles because local styles precede global styles.

Example

In the code below, you can see that we use selectors to reference 2 classes.

<!DOCTYPE html>
<html lang="en">
<head>
   <title>This is an example</title>
   <style>
      p.cen {
         color: red;
         text-align: center;
      }
      p.lar {
         font-size: 30%;
      }
   </style>
</head>
<body>
   <h1 class="cen">There will be no effect in this heading</h1>
   <p class="cen">The color of the paragraph will be red and it's alignment will be centered.</p>
   <p class=" cen lar">The color of the paragraph will be red and it's alignment will be centered and the font size will be large.</p>
</body>
</html>

Now, everything has its pros and cons, CSS has its cons too. So, let’s talk about the disadvantages of CSS.

Disadvantages of CSS

The following are the main disadvantages of CSS -

It can cause confusion - CSS has CSS 1 and CSS 3 versions, if the developer does not use the latest version, it may cause confusion in recent browsers, thus loading the CSS Issues arise when the style is correct.
Inconsistency between different browsers - CSS may work one way in one browser but may work differently on other browsers, here's why W3C recommends checking browser compatibility before running it using it.
Compatibility Issues - Some compatibility issues may arise after making some changes in CSS. This change may appear in some browsers and may lack security.
Beginner’s Confusion - The world of programming is huge as there are many languages with their own features. Different versions of CSS such as CSS2 and CSS3 can be confusing to those just starting out on their programming journey.
Cross-browser compatibility and beginner's difficulties - Different browsers use different logic to implement CSS stylesheets, which may hinder cross-browser compatibility, and in CSS Some levels may be difficult or confusing for some beginners and early developers.

in conclusion

CSS is an important pillar of web development because without CSS no styling is possible. It may seem confusing at first, but once you get the hang of it, working with CSS becomes a charm as a front-end developer. CSS was created as a method sheet language with the purpose of separating document content from document presentation. Document presentation includes color, layout, fonts, size, and more. The look and feel of a web page is the responsibility of CSS, which provides a lot of customization capabilities to users.
