full screen in 1920

Hi,
I can not pass JA FIt in full screen in 1920. I have read some posts without finding the solution, can you help me?
Thank you

tee-shot Hi. Please try add this to css:

.container {
    width: auto;
}

Thank,

I tried in custom.css and user.css in ja_fit/css, but it does not work and in ja_fit/css/themes/green/template.css it does not work either.

Thank.

Hi,
I found. In custom css put:

.container {
    width: auto;
}
@media (min-width: 1600px) {
  .t3-wrapper {
    width: 100%;
  }
.affix .t3-mainnav {
    width: 100%;
}
  
}

thank you for putting me on the track.

how to put resolved?
