The free version of Elementor isn’t lacking in features, but there are additional options with the Pro version. You do get everything that there is in the free version. However, you will also get additional features, like you can modify everything on your website, that includes headers, and footers, create templates, and more.
You will also be able to add more advanced features to your content, like forms, sliders, and pricing tables. Therefore, you can expand what types of pages you can build. And it saves you from having to add in more plugins from other developers.
Another very useful feature is the ability to add custom CSS directly to widgets and to create global widgets, which can be placed on numerous pages.
