The width of 1440px get and get what you want.
but if for example: I need a content part, was strictly not more than 1440px - einar_Pour commented on April 4th 20 at 13:11
Then try a property max-widht max width or min-widht. - cristal commented on April 4th 20 at 13:14
@einar_Pour, margin: 0 auto; - aisha_Goyette0 commented on April 4th 20 at 13:17

.content {
 max-width: 1440px;
 width: 100vw;

How it should work, in your opinion?
Set breakpoint for greater resolution.
100vw I already tried different options, just not removed when filled - einar_Pour commented on April 4th 20 at 13:13
