Why doesn't the header fit into the browser?

Question

css

Created a site layout in Photoshop. When creating, I specified the page width of 1380 px, now I don’t understand how to reduce it to the screen size without reworking the entire layout. What should be the resolution?

Answer 1

To make the header full screen, make the element width: 100%; Pixels are a static unit of measure, and percentages are elastic (that is, when zooming in and out of the screen, np. ctrl + and ctrl - with percentages will also change.)
