Need help with word press

I have worked on the header image for a long time and it keeps getting stretched out.

I could publish my password if someone wants to go into the admin and find out why this is happening.

Thank you!

Try using background-size: contain; instead of cover.

You mean go into the PHP code in wordpress? is there an easier way by going through the dashboard? thank you!

In your stylesheet for the website you just need to add;

.intro-header {
    background-size: contain;

Let me know if you are able to make that change. The name of the CSS file is clean-blog.css?ver=1.0

thanks, i tried that but it did not work

here is the password 12341234 name: admin

if you want to go in and look around you are welcome to!

thanks again
