Maybe you'd ever see about
Bold,
Italic, and
Underlined words before. Or even you'd ever made it in Microsoft Word or some kinds like in the typing program.
How do i make those in HTML?
Use <b> for Bold, <i> for Italic, and <u> for Underlined.
Example:
This is <b>Bold</b>, this is <i>Italic</i>, and this is <u>Underlined</u>.
And that will be like this:
This is
Bold, this is
Italic, and this is
Underlined
Try it yourself!
Rename learning.html to learning.txt, open it from Notepad and write those elements onto it.
Save and close it, rename it again from learning.txt to learning.html and open it from Internet Browser and see whether it is working or not. :)
