Don’t Write H1

In web development, CSS plays a crucial role in shaping the appearance of a website. It aids developers in designing websites according to a designed layout with enhanced aesthetic properties. One of the fundamental aspects of CSS is commenting out, and in this article, we will discuss commenting out in CSS.

Code Snippet

CSS allows developers to add comments to their code which do not affect the actual functioning of the website. This can be quite useful, especially if you need to provide extra information or explain complex lines of code. Here is a simple code snippet that signifies a CSS comment:

/* This is a CSS comment */
body {
  background-color: lightgrey;
}

Code Explanation

In this code snippet, the part that reads /* This is a CSS comment */, is a CSS comment.

CSS comments begin with /* and end with */. Everything in between these two symbols is interpreted as comments and thus ignored by the browser during code execution.

Therefore, in our example, This is a CSS comment is simply something that the coder has written for their reference and does not influence the rendering of the webpage by the browser. In fact, If these commentary lines weren’t present, the output would still remain the same.

The actual CSS rule in our code sets the background color of the webpage to light gray (background-color: lightgrey;). This piece of code is not inside comment symbols (/* and */), so it is executed by the browser, changing the background color of the webpage.

Using comments in your CSS code is a best practice followed by developers worldwide. Not only does it allow you to insert reminders or notes for yourself, but it also aids in improving the readability of the code for other developers. It is particularly useful in complex and long projects where codes can span over thousands of lines and can become messy and hard-to-understand without comments.
