button

Создает на странице кнопку и по действию напоминает тег input (с параметром button, reset или submit). В отличие от него button предлагает расширенные возможности для создания кнопок. К примеру, на такой кнопке можно размещать любые элементы html, в том числе изображения. С помощью стилей можно определить вид кнопки, изменив ее шрифт, фон или размер. Тег button должен располагаться внутри тега form, однако браузеры не выводят сообщения об ошибке и корректно работают с тегом button даже если он встречается вне формы. Но если результат нажатия на кнопку необходимо отправить на сервер, тег button обязательно должен находиться в теге form.

Пример:

Таблица 3×3
Lorem ipsum dolor sit amet, consectetur adipisicing elit	...	...
...	...	...
...	...	...

<table>
    <caption>Таблица 3×3</caption>
    <col/>
    <tbody>
        <tr>
            <td>Lorem ipsum dolor sit amet, consectetur adipisicing elit</td>
            <td>...</td>
            <td>...</td>
        </tr>
        <tr>
            <td>...</td>
            <td>...</td>
            <td>...</td>
        </tr>
        <tr>
            <td>...</td>
            <td>...</td>
            <td>...</td>
        </tr>
