Заголовки играют важную роль в структуре веб-страниц, помогая пользователям и поисковым системам понимать иерархию контента. В HTML существует шесть уровней заголовков, от <h1> до <h6>, где <h1> обозначает самый важный заголовок, а <h6> — наименее важный.
<h1>)Заголовок первого уровня используется для обозначения самого важного заголовка на странице. Обычно он представляет собой заголовок всей страницы или основного раздела.
<h1>Это заголовок первого уровня</h1>
<h2>)Заголовок второго уровня используется для подзаголовков внутри разделов, обозначенных <h1>.
<h2>Это заголовок второго уровня</h2>
<h3> — <h6>)Остальные заголовки используются для дальнейшего разделения контента на подкатегории.
<h3>Это заголовок третьего уровня</h3>
<h4>Это заголовок четвертого уровня</h4>
<h5>Это заголовок пятого уровня</h5>
<h6>Это заголовок шестого уровня</h6>
Правильное использование заголовков помогает создать четкую иерархию контента, что улучшает восприятие страницы как пользователями, так и поисковыми системами.

Стилизация заголовков осуществляется с помощью CSS. Вот пример, как можно изменить внешний вид заголовков.
<!DOCTYPE html>
<html>

<title>Стилизация заголовков</title>
<style>
h1 {
color: blue;
font-size: 32px;
}
h2 {

font-size: 28px;
}
h3 {

font-size: 24px;
}
</style>
</head>
<body>
<h1>Заголовок первого уровня</h1>

Не рекомендуется пропускать уровни заголовков, так как это может нарушить иерархию контента.
<!-- Неправильно -->
<h1>Основной заголовок</h1>
<h3>Подзаголовок третьего уровня</h3>
<!-- Правильно -->
<h1>Основной заголовок</h1>
<h2>Подзаголовок второго уровня</h2>
<h3>Подзаголовок третьего уровня</h3>
Не следует использовать заголовки только для изменения размера текста. Для этих целей лучше использовать CSS.
<!-- Неправильно -->
<h1>Этот текст не должен быть заголовком</h1>
<!-- Правильно -->
<p style="font-size: 32px;">Этот текст не должен быть заголовком</p>
Заголовки являются важным элементом HTML, помогающим структурировать контент и улучшать его восприятие. Правильное использование заголовков способствует лучшему SEO и улучшает пользовательский опыт.
Создайте веб-страницу, которая содержит следующие элементы:
<!DOCTYPE html>
<html>
<head>
<title>Изучение заголовков в HTML</title>
<style>
h1 {
color: navy;
font-size: 36px;
}
h2 {
color: darkred;
font-size: 30px;
}
h3 {
color: darkgreen;
font-size: 24px;
}
</style>
</head>
<body>
<h1>Изучение заголовков в HTML</h1>
<h2>Раздел 1</h2>
<h3>Подраздел 1.1</h3>
<p>Текст подраздела 1.1...</p>
<h3>Подраздел 1.2</h3>
<p>Текст подраздела 1.2...</p>
<h2>Раздел 2</h2>
<h3>Подраздел 2.1</h3>
<p>Текст подраздела 2.1...</p>
<h3>Подраздел 2.2</h3>
<p>Текст подраздела 2.2...</p>
