Form Layout

Vertical or basic form

BootStrap comes with the basic form structure. The steps for creating a basic form are as follows:

1. Add role = "form" to the parent <form> element ";
2. To get the best spacing, place the tag and control in a div. form-group, and the div under the parent form;
3. Add. form-control to all text elements <input>, <textarea>, and <select>.

<! DOCTYPE html> 
The input and label of form-controlClass are divided into two rows, and there is a blue border style when the focus is obtained.
Inline form

All the elements in the inline form are inline, and labels are side by side.
1. Add classfrom-inline to the <form> label;
2. Each form needs to be included in div. form-group. checkbox can be included in div. checkbox, and radio can be included in div. radio;
3. By default, input, select, and textarea in bootstrap have a width of 100%. When using inline forms, you can set the width of the Form Control;
4. Adding sr-only to the label description can hide the label description.
