Forms layout Utilities

Margin utilities are the easiest way to add some structure to forms. They provide basic grouping of labels, controls, optional form text, and form validation messaging. We recommend sticking to `margin-bottom` utilities, and using a single direction throughout the form for consistency.

Feel free to build your forms however you like, with `<fieldset>`s, `<div>`s, or nearly any other element.

Forms layout Grid

More complex forms can be built using our grid classes. Use these for form layouts that require multiple columns, varied widths, and additional alignment options.Requires the `$enable-grid-classes` Sass variable to be enabled (on by default).

Forms layout Gutters

By addinggutter modifier classes, you can have control over the gutter width in as well the inline as block direction.Also requires the `$enable-grid-classes` Sass variable to be enabled (on by default).

More complex layouts can also be created with the grid system.

Forms layout Horizontal form

Create horizontal forms with the grid by adding the `.row` class to form groups and using the `.col-*-*` classes to specify the width of your labels and controls. Be sure to add `.col-form-label` to your `<label>`s as well so they’re vertically centered with their associated form controls.

At times, you maybe need to use margin or padding utilities to create that perfect alignment you need. For example, we’ve removed the `padding-top` on our stacked radio inputs label to better align the text baseline.

Forms layout Horizontal form label sizing

Be sure to use `.col-form-label-sm` or `.col-form-label-lg` to your `<label>`s or `<legend>`s to correctly follow the size of `.form-control-lg` and `.form-control-sm`.

Forms layout Column sizing

As shown in the previous examples, our grid system allows you to place any number of `.col`s within a `.row`. They’ll split the available width equally between them. You may also pick a subset of your columns to take up more or less space, while the remaining `.col`s equally split the rest, with specific column classes like `.col-sm-7`.

Forms layout Auto-sizing

The example below uses a flexbox utility to vertically center the contents and changes `.col` to `.col-auto` so that your columns only take up as much space as needed. Put another way, the column sizes itself based on the contents.

You can then remix that once again with size-specific column classes.

Forms layout Inline forms

Use the `.col-auto` class to create horizontal layouts. By addinggutter modifier classes, we’ll have gutters in horizontal and vertical directions. The `.align-items-center` aligns the form elements to the middle, making the `.form-checkbox` align properly.
