Tired of having to update every single button style in your <a href="https://elementor.com/" rel="nofollow ugc">Elementor</a> website when the client asks for a change? Not too happy with Elementor’s default button Styles or Sizes? Do you wish you were able to modify, add or remove them? Then this plugin is just what you need!
Global Elementor Buttons standardizes Elementor Buttons with global classes that can be managed in a single place with custom css (and it works with both Elementor and Elementor Pro!).
<h3>Details</h3>
This plugin creates a new Elementor Widget, called Global Button that contains a simplified UI, just with the necessary controls to keep all of your buttons global and flexible. However, in the need of a special button, you can still add specific ids or classes to them!
Includes a handful of useful hooks for full flexibility: 
1. Set your own custom Style and Size classes (for example, btn-primary). 
2. Add / remove existent Style and Size classes. 
3. Change or remove the Style and Size prefix (for example, btn-primary). 
4. Edit the default Style and Size class.
For demonstration purposes, this plugin adds a minified version of the <a href="https://getbootstrap.com/docs/4.0/components/buttons/" rel="nofollow ugc">Bootstrap Buttons</a> stylesheet. Global Elementor Buttons allows you to remove this stylesheet, for performance and complexity reasons.
