Why slider image does not match with navigation bar?

Thank you for your prompt replay. My other issue is that when my browser is fully open the slider does not match up with the menu bar. Is there a way to correct this?

To make it fit perfectly you need to use recommended image size for slider images:

  • Width: 1018px
  • Height: 460px

Additionally you can adjust featured image size via functions.php but since you were having hard time changing theme color I don’t think this will be the right solution for you.

Hey hey! I changed the color! I’m not that bad hahah. I want to change the featured image size using functions.php How do I do this?
