> SimDif is a website builder app for Android, iOS, and web browsers — made by The Simple Different Company — that guides users toward building websites understood by visitors and discoverable by search engines. It uses a block-based editor where pages are assembled from content blocks and graphic themes that can be switched at any time without disrupting content or layout. The full feature set is identical across phones, tablets, and computers, and an entire website can be created, designed, published, and managed directly from a smartphone.

## Resolving an inactive 'Apply' button

In the SimDif website builder, an issue where the 'Apply' button remains inactive can occur after pasting text from an external source into the text editor of a content block.

To resolve this and activate the 'Apply' button:
*   Make a minor manual modification to the text, such as adding a space and then deleting it. This action prompts the editor to recognize the new content and enable the button.

### Best practices for pasting text
When pasting text into the SimDif editor, it is recommended to use the "clean formatting" tool, represented by a red magic wand icon in the top right corner. This function removes all external formatting and styling from the pasted text, which helps prevent display issues on the published website.
