## Description
Boxzilla is a WordPress popup builder for adding targeted popups, slide-ins, and
call-to-action boxes to your site. Show a box after a visitor scrolls, waits on
the page, views multiple pages, clicks a link, or reaches a specific page element.
Each box can contain any WordPress content, including shortcodes from form plugins.
Use Boxzilla for newsletter sign-up forms, content upgrades, product offers, important
notices, surveys, or any other message that should appear at the right moment without
taking over the whole page.
### What you can build with Boxzilla
* **Targeted WordPress popups** – show boxes only on the posts, pages, or conditions
you choose.
* **Scroll-triggered slide-ins** – open a box after a visitor scrolls past a percentage
of the page or reaches a specific element.
* **Timed call-to-action boxes** – show a message after a set number of seconds
on the page.
* **Pageview-based prompts** – wait until a visitor has viewed several pages before
showing a box.
* **Click-triggered modals** – open a box from a link, button, or URL hash such
as `#boxzilla-94`.
* **Flexible content** – add text, images, forms, shortcodes, embeds, or custom
HTML to any box.
* **Visual appearance controls** – choose the position, animation, colors, and
box style from the WordPress admin.
* **Dismissal control** – decide how long a box should stay hidden after a visitor
closes it.
* **Small front-end script** – Boxzilla adds only 6 kB of JavaScript to your website.
### Works with your forms and content
Boxzilla works with plugins that output shortcodes, including [Mailchimp for WordPress](https://wordpress.org/plugins/mailchimp-for-wp/).
Add the shortcode to your box content, choose when the box should appear, and publish
it.
### Premium add-ons
The core Boxzilla plugin is free. Paid add-ons are available for advanced triggers
and integrations, including exit-intent popups and time-on-site targeting.

## FAQ
### What does this WordPress popup plugin do?
Boxzilla lets you create popup, slide-in, modal, and call-to-action boxes for WordPress.
You choose the content, page targeting, trigger, animation, and dismissal behavior.
### Can I show a form inside a Boxzilla popup?
Yes. Boxzilla works with shortcode-based form plugins, including [Mailchimp for WordPress](https://wordpress.org/plugins/mailchimp-for-wp/).
Add the form shortcode to the box content and publish the box.
### Can I open a popup after someone clicks a link or button?
Yes. Link to the box ID from any link or button. For example, if your box ID is
94, use this link:
```
Open Box
```
### Can I open a box as soon as a page loads?
Yes. Configure this in the box settings, or add a URL hash such as `#boxzilla-13`
to the page URL. Replace `13` with the ID of the box you want to show.
### Can I customize the popup design?
Yes. Boxzilla includes appearance settings for the popup position, animation, and
style. You can also add custom CSS when you need more control.
```
.boxzilla { } /* all boxes */
.boxzilla-5 { } /* only the box with ID 5 */
```
### Will Boxzilla slow down my website?
Boxzilla adds only 6 kB of JavaScript to the front end. The script is built for
small, targeted popups and slide-ins.
### How do I disable automatic paragraphs in box content?
WordPress content filters are added to the `boxzilla_box_content` filter hook. You
can remove them with this code:
```
remove_filter( 'boxzilla_box_content', 'wptexturize' );
remove_filter( 'boxzilla_box_content', 'convert_smilies' );
remove_filter( 'boxzilla_box_content', 'convert_chars' );
remove_filter( 'boxzilla_box_content', 'wpautop' );
remove_filter( 'boxzilla_box_content', 'do_shortcode' );
remove_filter( 'boxzilla_box_content', 'shortcode_unautop' );
```
