background image doesn't scale to fit the site

Live demo: http://leoaivy.github.io/projects/poster_inside/html/1_P.01_login.html

Questoin: ".login-bg-wrap a img" work well on desktop with max-width set to 100%. But on narrower devices like iphone 6, the background images just scale to fit the width of view port, which make their height become smaller. I set heihgt to just 1% or 100% but they scale to their original size. I don't know why? And is there a way to make the height of these images fit the height of the site?

1 Answer

This is the expected behavior. When the viewport narrows, the image will scale height and width proportionately. If you want the entire area covered set your background-size property to cover. Of course, as the screen narrows more and more of the right side of the picture will be cut off but that's the trade-off.

If this is unacceptable, maybe use two different designs, something like a seamless tiling background or solid color as the default for smaller-width screens and then use a media query to display the picture for wider screens.
