Thememattic Support Team
We’ve looked into the website and it seems to be an issue with content inline CSS.
so We would like to suggest you following options
1) Edit the page/post through text field on content editor and remove inline CSS (recommended)
2) Or remove the css from style.css file itself. Kindly check and remove css from Line no 1962 of style.css
Note: This is not recommended as you’ll lose the changes on next theme update.
Kindly refer to: https://prnt.sc/hrgvbh
Hope this helps.
