Changing the container size inside nav-bar inbuilt

Hey I have my website which has really large number of items in the main navigation bar. So the design is to use full width but the inbuilt navigation bar has

Section
Section (which has logo etc)
Container (which has navigation links)

need this container to be 100 % but since it is a container I could see that max-width is defined as 940px in webflow.css , I fear changing this in webflow.css or overriding those parameters might hamper the other things which are automatically handled by webflow generated code.

Is there any other neat, clean way to do this ?

or we need to design a new nav-bar ourselves ?

fixed it by myself… i saw a parameter set if i make it as a custom class name and I managed to change the max width and it expanded as I liked… thanks
