Как сделать HTML-код неактивным с комментариями

У меня есть код HTML на странице, который я не хочу стирать, но неактивен для краткосрочной. Как заставить браузер игнорировать части страницы так же, как // работает на некоторых языках программирования?

Смотрите комментарии HTML:

Правильный способ удаления кода без его удаления, конечно же, заключается в использовании контроля версий, который позволяет вам воскресить старый код из прошлого. Не входите в привычку накапливать прокомментированный код на своих страницах, это не весело.:)

Комментарии HTML:

Комментарии к CSS:

/* This style will not apply */

Комментарии JavaScript:

// This single line JavaScript code will not execute

/* The whole block of JavaScript code will not execute */

Чтобы комментировать блок с вложенными комментариями: замените внутренние (блок) комментарии с «-» на «++»

 "--" & remove this comment *********************************************************************  <++! My document title ++>   <++! My document important HTML stuff ++>. . . ********************************************************************* * IMPORTANT: To uncomment section * sub inner comments "++" -> "--" & remove this comment ********************************************************************* -->

Таким образом, внешний комментарий большинства игнорирует все «недопустимые» внутренние (блокированные) комментарии.

Просто создайте многострочный комментарий вокруг него. Когда вы захотите вернуться, просто удалите теги комментариев.

Если вы используете Eclipse, то сочетание клавиш Ctrl + Shift + / , чтобы добавить группу код. Чтобы создать строку комментария или выбрать код, щелкните правой кнопкой мыши → Источник → Добавить комментарий блока.

Чтобы удалить комментарий блока, Ctrl + Shift + \ или щелкните правой кнопкой мыши → Источник → Удалить комментарий блока.

Вы уверены, что @PeterMortensen

hello

после нажатия Ctrl + Shift + / код превратится в hello -> при нажатии Ctrl + Shift + \ код превратится в < р>привет

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.

Html Code Block with Examples

Here is an example of how you can use these elements to create a code block:


 
// This is a code block 
function sayHello () console. log ( "Hello, World!" );
>

You can also use the element on its own to create a code block, like this:

 
// This is a code block 
function sayHello () console . log ( "Hello, World!" );
>

Note that the element preserves whitespace, so any indents or line breaks in your code will be preserved when it is displayed in the browser.

Here are a few more examples of how you can use the and elements to create code blocks in HTML:

Example 1: Use the and elements to display a block of HTML code:

Example 2: Use the element on its own to display a block of JavaScript code:

 
function sayHello () console . log ( "Hello, World!" );
>

Example 3: Use the element within a paragraph to display a block of code inline:

To run the script, use the following command : ./myscript.sh
