How expand the frontpage width in newsmag website?

Hi,

If you are referring to the width of the Newsmag theme, this is fixed. It is one of the main differences between Newspaper and Newsmag. The Newsmag theme has a fixed width, and it is not capable of having an increased width or full width, as Newspaper does. There is a guide here explaining some of the differences here https://tagdiv.com/newspaper-vs-newsmag-how-to-choose-the-perfect-wordpress-theme-for-your-project/

Please let me know if you have more questions.

Thank you!
