How to change the size of Yandex maps?

Question

Yandex maps

Suppose, on a large screen size, Yandex maps have a certain width, but when the screen is reduced, it is necessary that the map be full width. I tried to set ymaps width to 100%, but it did not help, apparently, the javascript code overlaps. How to set the width to 100% at low resolution?

Answer 1
