Image Full width?

Give this CSS a try:

.page-header-image.grid-container {
      max-width: 100%;
}

.page-header-image img {
      width: 100%;
}

Excuse me, where should I put it?

Sorry, already settled the issue child but do not know exactly where I paste that code is quite advanced the issue for me and I see that the degree of collaboration is not much, so if I'm bothering, better close the issue and I'll see how I'll fix it. The information provided does not solve the problem.

So you have the child theme installed?

If so, go to "Appearance > Editor" and paste the code I provided to the bottom of the editor.

Let me know if you need more info :)

I've already decided, by changing Page Header Position from Above Content Area.
Congratulations Tom. Your theme is wonderful.

That did what you were looking for? Perfect :)

Tip

Customize - Page Header Position -- set to Above Content Area
