html multiple fields differentiation on a form

i'm new to website development and i'm unsure of the technical word for this but i have a form with fields on it e.g.

User Info
Name 
Surname
Address

User Modules
Module Name 
Module Day 
....

At present i have these fields in a form showing one after another, there is no separation between them. Is there a function in html that i can use to make the form a bit more readable? e.g. (l开发者_如何转开发ike a group separation?) i know i can just indent the title but would like to know the proper way to do this.

User Info
    Name 
    Surname
    Address

User Modules
    Module Name 
    Module Day 
    ....

Use a FIELDSET and a LEGEND.
