    Class 7 - Worksheet 2

    1. Write a program in HTML to display the following :

    My first program                        ---------------------------- 1
    I am in class 7                               -----------------------------2

    Bishop Cotton Boys' School        -----------------------------3
     
    <html>
    <head>
    <title> Example 1</title>
    </head>
    <body >

    <b> My first program</b> <br>
     I am in  <I> class 7 </I> <p>
    <u> Bishop Cotton Boys' School</p>
    </body>
    </html>


    The  line1 is darker than the rest of the program. This is because of the bold tag. to go to the next line use the <br> tag.
    In line 2 , only class 7 is slanting , so use italics tag for that.
    There is a blank line between  line 2 and line 3, so paragraph tag should be used. Even if you close <p> before <u> tag also will give same effect.
    In line 3,a line is drawn below the whole sentence using <u> tag.

    2. What would be the output for the following program:
    <html>
    <head>
    <title> Example 2</title>
    </head>
    <body bgcolor=olive >                              ------------------1
    <font color=white size=6 face= Mistral> ------------------2
    Computers<br>Class 7 
    <p>
    Cottonnian shield...................

    </p>
    <!- I am going to draw a line - >               -----------------3
    <hr size=5  >                                             -----------------4
    </font>
    </body>
    </html>


    Line 1 : the background colour. The spelling is bgcolor.
    Line 2 : font color makes the text and numbers to turn to that particular colour. face changes the default font name to the name given.
    Line 3 : This is the comment line , which will not be displayed in the web browser.
    Line 4: The horizontal line with size 5
