Paragraphs

  • To load the webpage with information we can create paragraphs.
  • These are defined with the <p> tag.

<p align="left"> This is a paragraph aligned to the left side </p>

<p align="center"> This is another paragraph with center alignment</p>

Note: Each paragraph has to be enclosed within angle bracket, failing to do will become one large paragraph. HTML automatically adds an extra blank line before and after a paragraph.

 

Line Breaks

  • To make the webpage more presentable we need line breaks.
  • The <br> tag is used when you want to start a new line.

<p>This <br> is a para<br> graph with line breaks</p>

The below given lines show the output of the above syntax:

This

is a para

graph with line breaks

The <br> tag has no closing tag.

 

Backgrounds

  • To make the web page more attractive we can set background color or an image.

 

Bgcolor

  • The bgcolor attribute specifies a color to the background.
  • It can be a hexadecimal number, an RGB value, or a color name.

<body bgcolor="#000000">

<body bgcolor="rgb(0,0,0)">

<body bgcolor="black">

The lines that are given above – To set background-color black.

HTML Colors

  • HTML provides a simple and elegant way to sort the important information on a webpage.

    •  

    Unordered Lists:

    • An unordered list is a list of items marked with bullets.
    • An unordered list starts with the <ul> tag.
    • Each list item starts with the <li> tag.

    <ul>

    		  

    <li>Coffee</li>

    ·        ƒ Coffee

    <li>Milk</li>

    ·        ƒ Milk

    </ul>

    		  

     

    Ordered Lists:

    • An ordered list is also a list of items marked with numbers.
    • An ordered list starts with the <ol> tag.
    • Each list item starts with the <li> tag.

    This Code Would Display

    <ol>

    		  

    <li>Coffee</li>

    1. Coffee

    <li>Milk</li>

    2. Milk

    </ol>

    		  

     

    HTML Links – HTML uses the anchor tag to create a link to another document or web page.

    Email Links – To create an email link, you will use mailto: plus your email address.

    <a href="mailto:[email protected]">Email Help Desk</a>

    To add a subject for the email message, you would add ?subject= after the email address.

    For example:         

    <a href=" mailto:[email protected]?subject=Email Assistance">Email Help Desk</a>

    HTML Images:

    • The <img> tag has no closing tag.
    • To display an image on a page, you need to use the src attribute.
    • Src stands for "source".
    • The value of the src attribute is the URL of the image you want to display on your page.

    The syntax of defining an image:

    Output display:

    ”classTables:

    • Tables are defined with the <table> tag.
    • A table is divided into rows (<tr> tag), and each row is divided into data cells (<td> tag).
    • The letters td stands for table data, which is the content of a data cell.
    • A data cell can contain text, images, lists, paragraphs, forms, horizontal rules, tables, etc.

    <table>

    <tr>

    <td>row 1, cell 1</td>

    <td>row 1, cell 2</td>

    </tr>

    <tr>

    <td>row 2, cell 1</td>

    <td>row 2, cell 2</td>

    </tr>

    </table>

     

    Output display:

    row 1, cell 1 row 1, cell 2

    row 2, cell 1 row 2, cell 2

     

    Cell Padding and Spacing

    The <table> tag has two attributes known as cellspacing and cellpadding. These properties may be used separately or together.

    • Cellpadding is the pixel space between the cell contents and the cell border.
    • Cellspacing is the space between the cells.
