HTML Table

A HTML table is defined with the <table> tag. This allows HTML to arrange words in tabular form. Each table row is defined with the <tr> tag.

A table header is defined with the <th> tag. By default, the headings are bold and centered. A table data/cell is defined with the <td> tag.

HTML Code:

html
<table style = “width:100%>
<tr>
<th> LastName </th>
<th> FirstName </th>
<th> Age </th>
</tr>
<tr>
<td> William</td>
<td> Sam</td>
<td> 30 </td>
</tr>
</table>

Adding a border

You can add a border using a CSS border property to the table.

CSS Code:

html
Table, th, td {
Border: 1px solid black;
}

Don’t worry we are going to explain better in our CSS tutorial.

HTML Classes

The class attribute is used to specify a class for an HTML element. It is common to find multiple HTML elements sharing the same class.

HTML Code:

html
<style>
.cities {
Background-color:blue
Color: white;
Margin: 20px
Padding: 20px
}
</style>
<div class = “cities”>
<h2> London</h2>
<p> London is the capital of England </p>
</div>
<div class= “cities”>
<h2> Paris </h2>
<p> Paris is the capital of France </p>
</div>

HTML Id attribute

This is used to specify a unique id in an HTML document. It is used to point specific style declarations in a style sheet. Javascript also uses it to access and manipulate or change the element with the specific ID.

The syntax is written with a hash character "#" followed by an id name.

HTML Code:

html
<!DOCTYPE html>
<html>
<head>
<style>
#myHeader{
Background-color:lightbllue;
Color: black;
Padding: 40px;
Text-align: center;
}
</style>
</head>
<body>
<h1 id= “myHeader”>my Header</h1>
</body>
</html>

Difference between id and class

The difference lies in how they are used. A class name can be used by multiple HTML elements, while one HTML element within the page must only use an id name.

Conclusion
