Sticky CTA Button adds customizable floating Call-to-Action buttons and a back-to-top button to your website. Version 2.0 introduces a second CTA button and a responsive mobile/tablet action bar that pins your buttons to the edge of the screen on smaller devices.
Everything is configured from a clean, tabbed settings screen with a native WordPress color picker and a live preview.
<h4>Features</h4>
<ul>
<li>Two CTA buttons – Configure a primary and an optional second call-to-action, each with its own text, icon, link, target and colors.</li>
<li>Back-to-Top button – Smooth scrolling back to the top with selectable icons.</li>
<li>Responsive mobile action bar – On phones and tablets the CTAs turn into a full-width bar pinned to the bottom (or top) edge of the screen, while the back-to-top button floats above it. The activation breakpoint (phones, tablets or small laptops) is selectable.</li>
<li>Flexible desktop layout – Stack the buttons vertically or place them side by side, anchored to any of 8 screen positions with custom offsets.</li>
<li>Display behavior – Show the buttons immediately or reveal them after the visitor scrolls down.</li>
<li>Styling – Optional custom corner radius; lightweight emoji-based icons with no external font dependency.</li>
<li>Tabbed, professional settings – Organized into Buttons, Position & Layout, Mobile Bar and Styling, with a live preview and the native WordPress color picker.</li>
<li>Accessibility – Real button element for back-to-top, keyboard focus styles, reduced-motion and high-contrast support.</li>
<li>Performance – Dependency-free vanilla JavaScript with throttled scroll handling; assets load only when a button is enabled.</li>
<li>Translation ready – All strings are translatable via the <code>sticky-cta-button</code> text domain.</li>
</ul>

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.
<h3>What you can build with Boxzilla</h3>
<ul>
<li>Targeted WordPress popups – show boxes only on the posts, pages, or conditions you choose.</li>
<li>Scroll-triggered slide-ins – open a box after a visitor scrolls past a percentage of the page or reaches a specific element.</li>
<li>Timed call-to-action boxes – show a message after a set number of seconds on the page.</li>
<li>Pageview-based prompts – wait until a visitor has viewed several pages before showing a box.</li>
<li>Click-triggered modals – open a box from a link, button, or URL hash such as <code>#boxzilla-94</code>.</li>
<li>Flexible content – add text, images, forms, shortcodes, embeds, or custom HTML to any box.</li>
<li>Visual appearance controls – choose the position, animation, colors, and box style from the WordPress admin.</li>
<li>Dismissal control – decide how long a box should stay hidden after a visitor closes it.</li>
<li>Small front-end script – Boxzilla adds only 6 kB of JavaScript to your website.</li>
</ul>
<h3>Works with your forms and content</h3>
Boxzilla works with plugins that output shortcodes, including <a href="https://wordpress.org/plugins/mailchimp-for-wp/" rel="ugc">Mailchimp for WordPress</a>. Add the shortcode to your box content, choose when the box should appear, and publish it.
<h3>Premium add-ons</h3>
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.
