this is navabar page in which i'm using html , css and javascript
in css i'm using media query in media links height is auto becuase if we not used
then it will take toggle height and we use toggle button once it hide it can not be shown that's why
links height will be auto
in javascript i'm used add event listener in nav-toggle when click on navToggle button then it works as a toggle
toggle means if it show then hide
if its hide then show
here is the snap shot
