Commenting style in css

Comments in CSS

The stuff inside the /* */ marks are CSS comments. This allows you to enter notes into CSS that will not be interpreted. In this case, this comment lets someone reading the CSS file know that that particular line of CSS was intended to allow for using ems to set font size later in the CSS in a more intuitive base 10 way. Some CSS preprocessor syntax allow for JavaScript-style single-line comments, like this:

And actually, it’s a bit weird, but vanilla CSS also kind of supports that, it’s just a trick and you have to be careful.

Comments

Elaborating.. /*

* — Minor Section Heading —
*/ I prefer comment to appear this way, but everyone is different how they comment. One this thing is for sure. You can never comment too much! (as they stripped anyhow in css compression).

I have two little (newbie) questions:
1. Are comments still the same in CSS3?
2. What about comments in html5?

/* Comment Still a comment still a comment */ 

Ys, comments are same in css3 & html5 follow the html comments for html code, js comment for js code.

Yes. Commenting is as explained above in CSS3.
As for HTML5, you open with
It has worked for me both for single line commenting as well as multiple line commenting.

here comments has two types :
1) single line comments
2) Double line comments single line comments : method
it starts with double slash … //
while
double line comments :
start with /* ………………………*/
thanks

I don’t like the fact that you need 4 characters to comment a single instructions on a line! It would have been better to use something simpler in addition to the /* */. For example, SQL uses two consecutive dashes like — which is very easy to use, another one is a single quote at the beginning of the line like VB. Anyway, this is still better than the most silly comment syntax for HTML.

I have a followup question to determine if this is style or need. I see basic comments in css as described /* comment */.
Then I see multi line comments having a * before each new line.
Finally I will see what implies hierarchy as in this example from the normalize.css on github. Link Is this simply style and hierarchy or is there necessary syntax for multi line comments: /*! normalize.css v2.1.3 | MIT License | git.io/normalize */ /* ==========================================================================
HTML5 display definitions
========================================================================== */ /**
* Correct block display not defined in IE 8/9.
*/ article,aside,details,figcaption,figure,footer,header,hgroup,main,nav,section,summary display: block;>

Everything enclosed between /* and */ is treated as a comment regardless of how many lines they span, so any other apparent “syntax” you may see between those markers is really just a matter of arbitrary style/convention to improve legibility, especially useful when viewing non-highlighted code.

Как закомментировать CSS (и как писать комментарии)

Подпишись на наш телеграм-канал TechRocks WEB-разработка?

Комментарии — составляющая часть кода на любом языке программирования. Есть возможность комментирования и в CSS.

Если вы работаете в команде и занимаетесь большим проектом, вам нужна возможность как-то пояснять свой код товарищам. Тут вам на помощь придут комментарии.

Таблицы стилей со временем могут стать очень сложными и объемными. Поэтому систематическое добавление комментариев должно стать общепринятой практикой в команде.

В этой статье мы рассмотрим, как добавлять встроенные и многострочные комментарии в CSS.

Как закомментировать CSS

Чтобы закомментировать часть CSS-кода, вам понадобится обычный слэш ( / ) и астериск ( * ).

Для добавления как встроенного, так и многострочного комментария в CSS вы начинаете со слэша и астериска ( /* ). Их же, но в обратном порядке ( */ ) вы ставите в конце комментария.

Вот как выглядит встроенный (строчный) комментарий в CSS:

/* This is an inline comment in CSS */

А так выглядит многострочный комментарий:

/* This is a multi-line comment in CSS */

Вы также можете закомментировать те строки CSS, которые не должны выполняться:

С помощью комментариев обозначают начало и конец стилей отдельных разделов на веб-странице:

/* Hero section starts */ .hero < display: flex; align-items: center; justify-content: space-between; gap: 1.9rem; max-width: 1100px; margin: 2rem auto -6rem; >/* Hero section ends */

Комментарии помогут вам и тогда, когда вы хотите оставить примечание в вашем CSS для разработчиков, которые будут работать с вашим кодом после вас:

/* Don't override this style if you don't know what you are doing. Otherwise, CSS might give you a kick in the butt */

Организация CSS при помощи комментариев

Примечание редакции Techrocks: этот раздел взят из другой статьи — «CSS Comment Example – How To Comment Out CSS».

В более крупных проектах CSS-файлы могут быстро разрастись. В результате их может стать трудно поддерживать. Упорядочивание СSS и разделение кода на отдельные части поможет лучше ориентироваться в стилях в будущем. При этом стоит также создать «Содержание» документа:

/* * CSS TABLE OF CONTENTS * * 1.0 - Reset * 2.0 - Fonts * 3.0 - Globals * 4.0 - Color Palette * 5.0 - Header * 6.0 - Body * 6.1 - Sliders * 6.2 - Imagery * 7.0 - Footer */ /*** 1.0 - Reset ***/ /*** 2.0 - Fonts ***/ /*** 3.0 - Globals ***/ /*** 4.0 - Color Palette ***/ /*** 5.0 - Header ***/ /*** 6.0 - Body ***/ h2 < font-size: 1.2em; font-family: "Ubuntu", serif; text-transform: uppercase; >/*** 5.1 - Sliders ***/ /*** 5.2 - Imagery ***/ /*** 7.0 - Footer ***/

Заключение

В долгосрочной перспективе комментарии в СSS могут помочь вспомнить, что вы делали, когда писали тот или иной код.

Кроме того, если добавлять комментарии правильно, это облегчает работу над проектом, к которому вы возвращаетесь после долгого перерыва.

CSS Comments

CSS comments are not displayed in the browser, but they can help document your source code.

CSS Comments

Comments are used to explain the code, and may help when you edit the source code at a later date.

Comments are ignored by browsers.

A CSS comment is placed inside the element, and starts with /* and ends with */ :

Example

You can add comments wherever you want in the code:

Example

Comments can also span multiple lines:

Example

/* This is
a multi-line
comment */

HTML and CSS Comments

From the HTML tutorial, you learned that you can add comments to your HTML source by using the syntax.

In the following example, we use a combination of HTML and CSS comments:

Example

My Heading

Hello World!

This paragraph is styled with CSS.

CSS comments are not shown in the output.

Comments

A CSS comment is used to add explanatory notes to the code or to prevent the browser from interpreting specific parts of the style sheet. By design, comments have no effect on the layout of a document.

Syntax

Comments can be placed wherever white space is allowed within a style sheet. They can be used on a single line, or traverse multiple lines.

Examples

/* A one-line comment */ /* A comment which stretches over several lines */ /* The comment below is used to disable specific styling */ /* span < color: blue; font-size: 1.5em; >*/

    CSS Comment Example – How To Comment Out CSS

    

    Comments are used in CSS to explain a block of code or to make temporary changes during development. The commented code doesn’t execute.

    Both single and multi-line comments in CSS begin with /* and end with */ , and you can add as many comments to your stylesheet as you like. For example:

    /* This is a single line comment*/ .group:after < content: ""; display: table; clear: both; >/* This is a multi-line comment */

    You can also make your comments more readable by stylizing them:

    /* *** * SECTION FOR H2 STYLE *** * A paragraph with information * that would be useful for someone * who didn't write the code. * The asterisks around the paragraph * help make it more readable. *** */

    Organizing CSS with comments

    In larger projects, CSS files can quickly grow in size and become difficult to maintain. It can be helpful to organize your CSS into distinct sections with a table of contents to make it easier to find certain rules in the future:

    /* * CSS TABLE OF CONTENTS * * 1.0 - Reset * 2.0 - Fonts * 3.0 - Globals * 4.0 - Color Palette * 5.0 - Header * 6.0 - Body * 6.1 - Sliders * 6.2 - Imagery * 7.0 - Footer */ /*** 1.0 - Reset ***/ /*** 2.0 - Fonts ***/ /*** 3.0 - Globals ***/ /*** 4.0 - Color Palette ***/ /*** 5.0 - Header ***/ /*** 6.0 - Body ***/ h2 < font-size: 1.2em; font-family: "Ubuntu", serif; text-transform: uppercase; >/*** 5.1 - Sliders ***/ /*** 5.2 - Imagery ***/ /*** 7.0 - Footer ***/

    A little bit more about CSS: CSS Syntax and Selectors

    When we talk about the syntax of CSS, we’re talking about how things are laid out. There are rules about what goes where, both so you can write CSS consistently and a program (like a browser) can interpret it and apply it to the page correctly.

    There are two main ways to write CSS.

    Inline CSS

    Specifics on CSS Specificity: CSS Tricks

    Inline CSS applies styling to a single element and its children, until another style overriding the first is encountered.

    To apply inline CSS, add the “style” attribute to an HTML element that you’d like to modify. Inside quotes, include a semicolon-delimited list of key/value pairs (each in turn separated by a colon) indicating styles to set.

    Here’s an example of inline CSS. The words “One” and “Two” will have a background color of yellow and text color of red. The word “Three” has a new style that overrides the first, and will have a background color of green and text color of cyan. In the example, we’re applying styles to tags, but you can apply a style to any HTML element.

    Internal CSS

    While writing an inline style is a quick way to change a single element, there’s a more efficient way to apply the same style to many elements of the page at once.

    The internal CSS has its styles specified in the tag, and it is embedded in the tag.

    Here’s an example that has a similar effect as the “inline” example above, except the CSS has been extracted to its own area. The words “One” and “Two” will match the div selector and be red text on a yellow background. The words “Three” and “Four” will match the div selector too, but they also match the .nested_div selector which applies to any HTML element that references that class. This more specific selector overrides the first, and they end up appearing as cyan text on a green background.

     div < color: red; background: yellow; >.nested_div 
    One 
    Two
     
    Three
     
    Four
     

    The selectors shown above are extremely simple, but they can get quite complex. For example, it’s possible to apply styles only to nested elements; that is, an element that’s a child of another element.

    Here’s an example where we’re specifying a style that should only be applied to div elements that are a direct child of other div elements. The result is that “Two” and “Three” will appear as red text on a yellow background, but “One” and “Four” will remain unaffected (and most likely black text on a white background).

     div > div 
    One 
    Two
     
    Three
     
     
    Four
     

    External CSS

    All the styling has its own document which is linked in the tag. The extension of the linked file is .css
