To set marker inside of the box containing the bullet points, use the list-style-position property with the value inside.
The inside value means if the text goes onto a second line, the text will wrap underneath the marker. It will also appear indented to where the text would have started if the list had a value of outside.
Example
<html> <head> </head> <body> <ul style = "list-style-type:square;list-style-position:inside;"> <li>Maths</li> <li>Social Science</li> <li>Physics</li> </ul> <ol style = "list-style-type:lower-alpha;list-style-position:inside;"> <li>Maths</li> <li>Social Science</li> <li>Physics</li> </ol> </body> </html>
