want to move logo to left

@media (min-width: 992px){
    .kad-header-right {width: 78%; padding-left:0;}
    .kad-header-left {width:22%; padding-right:0;}
}

not working, i want to move logo to fully top left. i dont want any space in left side of logo.

ok, think I might be missing what you want. Try this to make the header fullwidth.

.headerclass > .container {
    width: 100%;
    padding: 0;
}

thanks working, but by using this my header image is not showing.

ok, I see that you are adding a background to your menu and that is covering up your header class background. You can use css like this to make sure the menu doesn’t stretch the screen:

#nav-main {
    max-width: 802px;
}
