2. Text Fields/Password Fields/Radio Buttons/Check Boxes/Simple dropdown box/Fieldset/Textarea/Button
|------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| Text Fields | html <form action=""> <input type = "text" name="user"> </form>

| Defining <label> for button | Eachbutton should have alabel <label>: defines a label for an <input> element; allow a user to click on the label as well as the button The for attribute of the <label> tag = the id attribute of the related element |
| Defining <label> for button | > <form action="demo_form.asp"> > <label for = "male">Male</label> > <input type = "radio" name="sex" id = "male" value="male">Male > <label for = "female">Female</label> > <input type = "radio" name="sex"id = "female" value="female">Female > <input type = "submit" value="Submit"> > </form> |
