Bootstrap provides three forms: vertical forms, inline forms, and horizontal forms. Next we will introduce you one by one. If you are interested, study together.

Create a vertical or basic form:

• Add role = "form" to the parent <form> element ".
• Place tags and controls in a <div> with class. form-group. This is required to obtain the optimal spacing.
• Add class. form-control to all text elements <input>, <textarea>, and <select>

<Form role = "form"> <div class = "form-group"> <label for = "name"> name </label> <input type = "text" class = "form-control" id = "name" placeholder = "enter a name"> </div> <div class = "form-group"> <label for = "inputfile"> file input </label> <input type = "file" id = "inputfile"> <p class = "help-block"> here is an instance of block-level help text. </P> </div> <div class = "checkbox"> <label> <input type = "checkbox"> check </label> </div> <button type = "submit" class = "btn-default"> submit </button> </form>

Inline form:

All the elements in the inline form are aligned to the left and labels are side by side. To create an inline form, you must add the class to the form label.

. Form-inline

<Form class = "form-inline" role = "form"> <div class = "form-group"> <label class = "sr-only" for = "name"> name </label> <input type = "text" class = "form-control" id = "name" placeholder = "enter a name"> </div> <div class = "form-group"> <label class = "sr-only" for = "inputfile"> file input </label> <input type = "file" id = "inputfile"> </div> <div class = "checkbox"> <label> <input type = "checkbox"> check </label> </div> <button type = "submit" class = "btn-default"> submit </button> </form>

The display effect is as follows:

Note: by default, the input, select, and textarea values in Bootstrap are 100% in width. When using an inline form, you must set a width on the Form Control.

Horizontal form: Unlike the other two forms, follow these steps to create a horizontal form.

• Add class. form-horizontal to the parent <form> element.

• Place tags and controls in a <div> with class. form-group.

• Add class. control-label to the label.

For example:

<Form class = "form-horizontal" role = "form"> <div class = "form-group"> <label for = "firstname" class = "col-sm-2 control-label"> name </label> <div class = "col-sm-10"> <input type = "text" class = "form-control" id = "firstname" placeholder = "enter a name"> </div> <div class = "form-group"> <label for = "lastname" class = "col-sm-2 control-label"> surname </label> <div class = "col-sm-10"> <input type = "text" class = "form-control" id = "lastname" placeholder = "Enter the last name"> </div> </div> <div class = "form-group"> <div class = "col-sm-offset-2 col-sm-10"> <div class = "checkbox"> <label> <input type = "checkbox"> remember me </label> </div> <div class = "form-group"> <div class = "col-sm-offset-2 col-sm-10"> <button type = "submit" class = "btn-default"> logon </button> </div> </form>
