Hello Ozgur,
I’ve checked the URL that you’ve sent. There are some alignment issues.
- For the buttons remove the alignfull and set it to align none
- For the wp-block-columns remove alignwide and set it to none.
- Lastly for the third pricing column you should set background color, right now its default dark so the text is not seen.
If you encounter any further issues or have any confusions, feel free to reach out.
Thanks
