HTML preprocessors can make writing HTML more powerful or convenient. For instance, Markdown is designed to be easier to write and read for text documents and you could write a loop in Pug.
In CodePen, whatever you write in the HTML editor is what goes within the <body>
tags in a basic HTML5 template. So you don't have access to higher-up elements like the <html>
tag. If you want to add classes there that can affect the whole document, this is the place to do it.
In CodePen, whatever you write in the HTML editor is what goes within the <body>
tags in a basic HTML5 template. If you need things in the <head>
of the document, put that code here.
The resource you are linking to is using the 'http' protocol, which may not work when the browser is using https.
CSS preprocessors help make authoring CSS easier. All of them offer things like variables and mixins to provide convenient abstractions.
It's a common practice to apply CSS to a page that styles elements such that they are consistent across all browsers. We offer two of the most popular choices: normalize.css and a reset. Or, choose Neither and nothing will be applied.
To get the best cross-browser support, it is a common practice to apply vendor prefixes to CSS properties and values that require them to work. For instance -webkit-
or -moz-
.
We offer two popular choices: Autoprefixer (which processes your CSS server-side) and -prefix-free (which applies prefixes via a script, client-side).
Any URL's added here will be added as <link>
s in order, and before the CSS in the editor. If you link to another Pen, it will include the CSS from that Pen. If the preprocessor matches, it will attempt to combine them before processing.
You can apply CSS to your Pen from any stylesheet on the web. Just put a URL to it here and we'll apply it, in the order you have them, before the CSS in the Pen itself.
If the stylesheet you link to has the file extension of a preprocessor, we'll attempt to process it before applying.
You can also link to another Pen here, and we'll pull the CSS from that Pen and include it. If it's using a matching preprocessor, we'll combine the code before preprocessing, so you can use the linked Pen as a true dependency.
JavaScript preprocessors can help make authoring JavaScript easier and more convenient.
Babel includes JSX processing.
Any URL's added here will be added as <script>
s in order, and run before the JavaScript in the editor. You can use the URL of any other Pen and it will include the JavaScript from that Pen.
You can apply a script from anywhere on the web to your Pen. Just put a URL to it here and we'll add it, in the order you have them, before the JavaScript in the Pen itself.
If the script you link to has the file extension of a preprocessor, we'll attempt to process it before applying.
You can also link to another Pen here, and we'll pull the JavaScript from that Pen and include it. If it's using a matching preprocessor, we'll combine the code before preprocessing, so you can use the linked Pen as a true dependency.
Search for and use JavaScript packages from npm here. By selecting a package, an import
statement will be added to the top of the JavaScript editor for this package.
Using packages here is powered by Skypack, which makes packages from npm not only available on a CDN, but prepares them for native JavaScript ES6 import
usage.
All packages are different, so refer to their docs for how they work.
If you're using React / ReactDOM, make sure to turn on Babel for the JSX processing.
If active, Pens will autosave every 30 seconds after being saved once.
If enabled, the preview panel updates automatically as you code. If disabled, use the "Run" button to update.
If enabled, your code will be formatted when you actively save your Pen. Note: your code becomes un-folded during formatting.

# New Bootstrap v5 forms
A quick look at some of the major changes coming to form controls in Bootstrap 5.
## Checks
<hr class="mt-2 mb-3">
Taking a fresh pass at custom checkboxes and radios without psuedo-elements, thus replacing our previous native form control styles. By resetting the `appearance`, we should be able to style the inputs across Edge, Chrome, Firefox, and Safari.
**Differences from v4:**
- Custom form controls are the new native.
- No more custom HTML is required for the new form controls. They're 100% styled from the `<input>` itself with `appearance: none;`.
- Form controls are 25% larger, moving from `1rem` (`16px`) to `1.25em` (`20px`).
- Form controls are now built with `em`s instead of `rem`s for easy sizing.
- Instead of `position: absolute;`, `<input>`s are aligned with `float` and `margin-top` to help align and scale with sizing options.
- No more `.custom-checkbox-inline` modifier class—instead, use utilities for way more flexibility in your layouts.
These new checks and their text are aligned the same way as v4—with `padding-left` on the outer container. This is so any and all siblings to the `<input>` (like the `<label>`, help text, or validation feedback) is easily aligned.
Flexbox styles were originally attempted, but they're unnecessary and were abandoned early in favor of a `float`ed `<input>`.
### Default styles
<div class="flex-check">
<input class="flex-check-input" type="checkbox" id="check1" checked>
<label class="flex-check-label" for="check1">This is the new custom checkbox</label>
<small class="text-muted d-block">Some additional help text could appear right here.</small>
</div>
<div class="flex-check">
<input class="flex-check-input" type="checkbox" id="checkindeterminate">
<label class="flex-check-label" for="checkindeterminate">This is an indeterminate custom checkbox</label>
<small class="text-muted d-block">Indeterminate checkboxes must be toggled via JavaScript—there's no HTML attribute for this.</small>
</div>
<div class="flex-check">
<input class="flex-check-input" type="checkbox" id="longcheck">
<label class="flex-check-label" for="longcheck">This is the new custom checkbox with text that wraps to multiple lines because of a super long label that I keep adding text to so that it does that whole wrapping thing easily enough.</label>
</div>
<div class="flex-check">
<input class="flex-check-input" type="checkbox" id="disabledcheck" disabled>
<label class="flex-check-label" for="disabledcheck">This is the new disabled custom checkbox</label>
</div>
<br>
<div class="flex-check">
<input class="flex-check-input" type="radio" id="radio1" name="radios" checked>
<label class="flex-check-label" for="radio1">Custom radio that's checked</label>
</div>
<div class="flex-check">
<input class="flex-check-input" type="radio" id="radio2" name="radios">
<label class="flex-check-label" for="radio2">Custom radio that isn't</label>
</div>
<div class="flex-check">
<input class="flex-check-input" type="radio" id="radio3" name="radios" disabled>
<label class="flex-check-label" for="radio3">Custom radio that's disabled</label>
</div>
<br>
<div class="flex-check flex-switch">
<input class="flex-check-input" type="checkbox" id="switch1">
<label class="flex-check-label" for="switch1">Custom switch checkbox input</label>
</div>
<div class="flex-check flex-switch">
<input class="flex-check-input" type="checkbox" id="switch2" disabled>
<label class="flex-check-label" for="switch2">Disabled custom switch checkbox input</label>
</div>
<br>
<div class="flex-check flex-switch">
<input class="flex-check-input" type="radio" id="switchradio1" name="switchradio">
<label class="flex-check-label" for="switchradio1">Custom switch radio that's checked</label>
</div>
<div class="flex-check flex-switch">
<input class="flex-check-input" type="radio" id="switchradio2" name="switchradio">
<label class="flex-check-label" for="switchradio2">Second custom switch radio</label>
</div>
### Without label
And without labels inside the wrapper:
<div class="form-group row">
<label class="col-md-3" for="check-no-label">External label</label>
<div class="col-md-9">
<div class="flex-check">
<input class="flex-check-input" type="checkbox" id="check-no-label" checked>
</div>
</div>
</div>
<div class="form-group row">
<label class="col-md-3" for="switch-no-label">External label</label>
<div class="col-md-9">
<div class="flex-check flex-switch">
<input class="flex-check-input" type="checkbox" id="switch-no-label" checked>
</div>
</div>
</div>
### Inline
Make any checkbox, radio, or switch appear "inline" with utility classes. We recommend `.d-inline-block` and `margin` utilities (e.g., `.mr-3`) as needed.
<div class="flex-check d-inline-block mr-3">
<input class="flex-check-input" type="checkbox" id="checkInline1" checked>
<label class="flex-check-label" for="checkInline1">Inline checkbox</label>
</div>
<div class="flex-check d-inline-block mr-3">
<input class="flex-check-input" type="checkbox" id="checkInline2">
<label class="flex-check-label" for="checkInline2">Another one</label>
</div>
<div class="flex-check flex-switch d-inline-block">
<input class="flex-check-input" type="checkbox" id="switchInline1">
<label class="flex-check-label" for="switchInline1">Inline switch</label>
</div>
### Sizing
Built with `em` units, custom checks, radios, and switches will scale to their own `font-size`, or their containing element's (explicit or inherited) `font-size`. Here we're using a modifier class to set `font-size: 1.5rem` on the container.
<div class="flex-check flex-check-lg">
<input class="flex-check-input" type="checkbox" id="sizingcheck1">
<label class="flex-check-label" for="sizingcheck1">Resized custom check</label>
</div>
<div class="flex-check flex-check-lg">
<input class="flex-check-input" type="radio" id="sizingradio1" name="sizingradios">
<label class="flex-check-label" for="sizingradio1">Resized custom radio</label>
</div>
<div class="flex-check flex-switch flex-check-lg mb-3">
<input class="flex-check-input" type="checkbox" id="sizingswitch1">
<label class="flex-check-label" for="sizingswitch1">Resized custom switch checkbox</label>
</div>
Note that you could scope the sizing to the `<input>` itself, but you'll need additional styles to change the indentation of the `<label>`'s text. Alternatively, you could set a `font-size` on the wrapper and then override the `<label>`'s `font-size`.
<div class="flex-check flex-switch" style="font-size: 1.5rem;">
<input class="flex-check-input" type="checkbox" id="sizingSwitch2">
<label class="flex-check-label" for="sizingSwitch2" style="font-size: 1rem;">Large switch, normal label text</label>
</div>
## Selects
<hr class="mt-2 mb-3">
Without the `.form-select`, the previous `.custom-select` is going to become the default styling, providing a unified look across all platforms.
### Default styles
Below are the default and disabled selects. Disabled styles are the same as our checks—no `pointer-events` and an `opacity` change.
<select class="flex-select mb-3">
<option selected>Open this select menu</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
</select>
<select class="flex-select" disabled>
<option selected>Disabled select menu</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
</select>
### Inline
Similar to the new checks, make selects inline with a modifier class: `.w-auto`. Selects are `inline-block` to begin with, so no need to change their `display`.
<div class="mb-3">
<select class="flex-select w-auto mr-3">
<option selected>Open this select menu</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
</select>
<div class="flex-check d-inline-block">
<input class="flex-check-input" type="checkbox" id="selectInlineCheck">
<label class="flex-check-label" for="selectInlineCheck">Inline checkbox</label>
</div>
</div>
Vertical alignment may become an issue, so consider wrapping your inline form controls in some flex and margin utilities. The example below features a wrapper with `.d-flex` and `.align-items-center`, plus `.mb-0` on the inline checkbox.
<div class="d-flex align-items-center">
<select class="flex-select w-auto mr-3">
<option selected>Open this select menu</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
</select>
<div class="flex-check d-inline-block mb-0">
<input class="flex-check-input" type="checkbox" id="selectInlineCheck2">
<label class="flex-check-label" for="selectInlineCheck2">Inline checkbox</label>
</div>
</div>
### Sizing
Sizing should become similar to the new checks and switches as they're now built with `em`s. Below is the same select as above, but with an increased `font-size` of `1.5rem`.
<select class="flex-select mb-3" style="font-size: 1.5rem;">
<option selected>Open this select menu</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
</select>
And making it smaller with `font-size: .875rem;`.
<select class="flex-select mb-3" style="font-size: .875rem;">
<option selected>Open this select menu</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
</select>
### Multiple and size attributes
Adding `multple` or `size` should render the select as expected, though with (expected) limited styling of the `<option>`s.
<select class="flex-select mb-3" multiple>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
<option value="4">Four</option>
<option value="5">Five</option>
</select>
<select class="flex-select mb-3" size="3">
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
<option value="4">Four</option>
<option value="5">Five</option>
</select>
