How To Style the HTML element with CSS

This tutorial will introduce you to styling the HTML Content Division element—or element—using CSS. The element can be used to structure the layout of a page and break up a webpage into separate components for individual styling. In this tutorial, you will create and style elements, as well as learn how to add and style other elements inside a container. These skills will prepare you to use elements as layout tools later on in the series when you begin recreating the demonstration website.

The

element is used by adding opening and closing

tags to an HTML document. On its own, the

element typically has little visual effect on the presentation of a webpage. To specify the size, color, and other properties of a

element, you can assign it style rules using CSS.

Prerequisites

To follow this tutorial, make sure you have set up the necessary files and folders as instructed in a previous tutorial in this series How To Set Up You CSS and HTML Practice Project.

Exploring the Element in Practice

Let’s try a hands-on exercise to study how the element works. Erase everything in your styles.css file (if you added content from previous tutorials). Next, add the following CSS rule for the tag selector:

div  background-color: green; height: 100px; width: 100px; >

Save the styles.css file. Next, return to your index.html file, erase everything that’s there (except for the first line of code: ) and add the following code snippet:

Notice that the element has opening and closing tags but does not require any content. Save the index.html file and reload it in your browser. (For instructions on loading an HTML file, please visit our tutorial step How To View An Offline HTML File In Your Browser).

Your webpage should display a green box 100 pixels wide and 100 pixels tall as specified by the CSS rule:

Webpage with green <div data-lazy-src=

box.»/>

Now that you have a styling rule for your element, every element you add to your page will be styled in the precisely the same manner. However, when creating a website, it is unlikely that you will want all of your HTML elements to be styled in the same way. For this reason, developers often create classes that they can use to style elements in different ways.

To practice creating classes for elements, erase the CSS rule you just created and add the following new three CSS rulesets to the styles.css file:

.div-1  background-color: blue; height: 50px; width: 50px; > .div-2  background-color: red; height: 100px; width: 100px; > .div-3  background-color: yellow; height: 200px; width: 200px; >

In this code snippet, you have created styling rules for three different classes: div-1 , div-2 , and div-3 . Note that you have added a . before the class selector as required when declaring CSS rules for classes.

Save the styles.css file and return to your index.html file. Erase the element you just created and, add the three elements to your index.html file, applying a class to each one that corresponds to the CSS class selectors that you defined in styles.css :

div class="div-1">div> div class="div-2">div> div class="div-3">div>

Note that you have added the class as an attribute to the tag by adding the class attribute and class name to each opening tag. Save the file and reload it in your browser. You should receive something like this:

Adding and Styling Text in a Container

You can put text inside a container by inserting text in between the opening and closing tags. Try adding text inside each of the elements in your index.html file:

div class="div-1">Bluediv> div class="div-2">Reddiv> div class="div-3">Yellowdiv>

Save the file and reload it in your browser. You should now have text displayed in each of your containers:

You can add additional HTML elements to your text inside the elements. For example, try adding the HTML heading tags ( to ) to your text inside the tags in your index.html file:

div class="div-1">h2>Blueh2>div> div class="div-2">h3>Redh3>div> div class="div-3">h4>Yellowh4>div>

Save the file and reload it in your browser. The text inside the containers should now be styled according to the default properties of the to tags:

Note that the elements have also adjusted their positions slightly. This repositioning is caused by the default margin properties of the through elements. You’ll learn more about margins in the next tutorial on the CSS Box Model, but for now it is fine to ignore them

To style text inside the containers, you can specify text property values in the rulesets for your classes. Try adding the properties and values to your rulesets in your styles.css file as highlighted in the in the following code snippet:

.div-1  background-color: blue; height: 50px; width: 50px; font-size: 10px; color: white; iu > .div-2  background-color: red; height: 100px; width: 100px; font-size: 20px; color: yellow; > .div-3  background-color: yellow; height: 200px; width: 200px; font-size:30px; color: blue; >

Save your styles.css file and reload the index.html file in your browser. The text inside the containers should now be styled according to the CSS rules in your styles.css file:

containers»/>

Conclusion

In this tutorial you explored how to style the color and size of a element and how to add and style text inside a element. You will use the element to control the layout of a page when you begin building the website. In the next tutorial, you will learn about the CSS Box Model, and how to use it to adjust the size of an element’s content, padding, borders, and margin.

Когда задано свойство content , то элемент заменяется на значение этого свойства. В качестве значения могут быть переданы различные типы: изображение, градиент или текст.

Пример

Изображение в качестве содержимого. Может применяться к любому элементу.

 div  content: url("http://www.example.com/test.png");> div  content: url("http://www.example.com/test.png"); >

Все значения ниже могут применяться ТОЛЬКО к псевдоэлементам : : before и : : after .

 div::before  content: "prefix";> div::before  content: "prefix"; >

Значения счётчиков с использованием функций counter ( ) и counters ( ) :

 div::before  content: counter(chapter_counter);> div::before  content: counters(section_counter, ".");> div::before  content: counter(chapter_counter); > div::before  content: counters(section_counter, "."); >

Значения HTML-атрибутов с использованием функции attr ( ) :

 div::before  content: attr(value string);> div::before  content: attr(value string); >

Ключевые слова, зависящие от языка страницы и положения в тексте:

 div::before  content: open-quote; content: close-quote; content: no-open-quote; content: no-close-quote;> div::before  content: open-quote; content: close-quote; content: no-open-quote; content: no-close-quote; >

Использование нескольких значений одновременно. Исключение — ключевые слова normal и none :

 div::before  content: open-quote counter(chapter_counter);> div::before  content: open-quote counter(chapter_counter); >

Ключевые слова, которые нельзя комбинировать с другими значениями:

 div::before  content: normal; content: none;> div::before  content: normal; content: none; >

Чаще всего свойство content применяется к псевдоэлементам : : before и : : after . В зависимости от значения свойства псевдоэлемент принимает тот или иной вид:

Если значением является просто строка, то она подставляется на место псевдоэлемента. Как правило, это до или после текстового содержимого тега.

Есть несколько зарезервированных слов, которые также можно указывать в качестве значения. Используются они как совместно со свойством quotes , так и в автоматическом режиме:

open — quote обозначает открывающую кавычку цитаты для текущего языка. Например, для русского это будет открывающая «ёлочка» ( « );
close — quote обозначает закрывающую кавычку цитаты для текущего языка. Например, для русского это будет закрывающая «ёлочка» ( » );

   Вспомните, как говорили мушкетёры: Один за всех, все за одного!  blockquote> Вспомните, как говорили мушкетёры: q>Один за всех, все за одного!q> blockquote>

 blockquote  quotes: "«" "»" "„" "”";> blockquote::before  content: open-quote;> blockquote::after  content: close-quote;> blockquote  quotes: "«" "»" "„" "”"; > blockquote::before  content: open-quote; > blockquote::after  content: close-quote; >

«Вспомните, как говорили мушкетёры: „Один за всех, все за одного!”»

no — open — quote и no — close — quote используются, когда не нужно отображать кавычки, но при этом продолжать увеличивать уровень вложенности;
Если значением является результат выполнения функций counter ( ) или counters ( ) , то псевдоэлемент будет содержать вычисленное значение счётчика в текущий момент. Эти функции работают совместно со свойствами counter — reset и counter — increment ;
Очень интересным значением является результат выполнения функции attr ( ) .

С помощью неё можно вывести в псевдоэлемент значение любого атрибута тега:

   Ваш рейтинг: 212  p> Ваш рейтинг: span data-tip="Вычисляется на основе активности">212span> p>

 [data-tip]  position: relative; cursor: help;> [data-tip]:hover::after  opacity: 1; visibility: visible;> [data-tip]::after  content: attr(data-tip); position: absolute; top: 140%; left: 50%; transform: translateX(-50%); opacity: 0; visibility: hidden;> [data-tip]  position: relative; cursor: help; > [data-tip]:hover::after  opacity: 1; visibility: visible; > [data-tip]::after  content: attr(data-tip); position: absolute; top: 140%; left: 50%; transform: translateX(-50%); opacity: 0; visibility: hidden; >

🛠 . или красиво оформить нумерованный перечень

 .benefits  counter-reset: benefits;> .benefits-item  counter-increment: benefits;> .benefits-item::before  content: counter(benefits); position: absolute; font-size: 190px; font-weight: bold; left: 0; top: -0.35em; opacity: 0.5; color: #1A5AD7;> .benefits  counter-reset: benefits; > .benefits-item  counter-increment: benefits; > .benefits-item::before  content: counter(benefits); position: absolute; font-size: 190px; font-weight: bold; left: 0; top: -0.35em; opacity: 0.5; color: #1A5AD7; >
