.form-search to the form and
.search-query to the
input for an extra-rounded text input.
.form-inline for left-aligned labels and inline-block controls for a compact layout.
Right align labels and float them to the left to make them appear on the same line as controls. Requires the most markup changes from a default form:
.form-horizontalto the form
.control-labelto the label
.controlsfor proper alignment
Checkboxes are for selecting one or several options in a list while radios are for selecting one option from many.
.inline class to a series of checkboxes or radios for controls appear on the same line.
.add-on and an
input with one of two classes to prepend or append text to an input.
Use both classes and two instances of
.add-on to prepend and append an input.
Instead of a
span with text, use a
.btn to attach a button (or two) to an input.
Use relative sizing classes like
.input-large or match your inputs to the grid column sizes using
.col-sm-12 for inputs that match the same sizes of the grid columns.
