(preformatted) tag, spaces and line breaks aren't ignored. Just look into the simple text example below: You can easily print the code with the same approach. Just place it inside 
tag, and that's it. There is another tag combined with 
tag, which gives more semantic meaning to search engines. The HTML code tag. tag is used for the piece of computer code. Usually, you include this tag inside of the 
tag to tell a browser, and Google that’s a block of code you want to display, not to render. Here is an example:

Write Code Blocks in HTML
 
This article will introduce a few methods of writing blocks of code snippets in HTML.
 
Wrap the Tag and Its Contents Inside the Tag to Write Code Block in HTML
 
The tag defines a piece of computer code. The content inside is displayed in the browser’s default monospace font.
 
The tag is used to represent code blocks in HTML. The tag is an inline tag.
 
It means that if we write code snippets inside the tag, the contents inside of the tag are displayed in a line. It does not preserve line breaks or spaces.
 
The tag defines preformatted text. Any text in a element is displayed in a fixed-width font, and the text preserves both spaces and line breaks.
 
The text or contents inside the tag will be displayed as written exactly in the HTML source code. The tag is a block-level element.
 
If we wrap the tag and its contents inside the tag, the contents inside the tag will behave as a block-level element. The contents will have the monospace font, and the line breaks and spaces of the code snippets will also be preserved.
 
For example, write some JavaScript code and wrap the code inside the tag. Next, wrap the element with a tag.
 
p>Code snippet for addition of two numbers in javascriptp> pre>  code>  function add (a,b)   sum = a + b;  return sum;  >  code>  pre> 
 
The above example will display the JavaScript code block.
 
Use the Tag and the CSS white-space Property to Write Code Block in HTML
 
In this method, we will seek a replacement for the tag using some CSS styles. Previously, we knew the element was an inline element.
 
We used the tag to make it a block-level element. But, we can also make the tag a block-level element by setting its display property to block .
 
And we can preserve the line breaks and spaces of the code tag by setting its white-space property to pre-wrap . As a result, it will display code snippets as written in HTML source code.
 
Thus, we will be able to create code blocks in HTML.
 
For example, create a tag and write some JavaScript code snippet inside it. Give the tag a class name of the sum .
 
In CSS, select the sum class and set the display property to block and the white-space property to pre-wrap .
 
code class="sum">  function (a, b)   sum = a + b;  return sum;  >  code> 
 
.sum   display: block;  white-space: pre-wrap; > 
 
The code examples above will produce a JavaScript code block.
