如何使我的导航栏项目响应地在屏幕上伸展

Question

I'm wanting items in my nav bar to stretch across the width of the screen when on lets say a laptop, and go one-under another when on a phone.

Also, I don't like how my items are pushed over to the left , i want them to be equally spaced across the screen.

HTML:

<!-- Logo -->

Answer 1

If I understand you correctly, there are some changes you should do:

1. Read the css I added. I'm using flex to stretch the item equally in the menu.
2. Remove the .container div to stretch the navigation to the width of the window.
3. Remove the .navbar-right class from the navigation you don't need it.

I didn't take care about the mobile I'm sure you know how to do all those changes in desktop only using media query.

 .navbar-brand, .navbar-nav, .navbar-nav>li { float:none !important; } .navbar-nav { display:flex; } .navbar-nav>li { flex: 1; }

You will have to use media queries to get responsive view.

.navbar-brand{
  width:100%;
  display:inline-block;
}
.navbar-brand ul li{
  width:20%; 
  /*Adjust the percent based on 100/number of items (Here it is 5)*/
  min-width:150px;
  /*Keep a minimum width such that the text does not overflow*/
  display:inline-block;
  text-align:center;
}

/*Write media queries for Mobile and tablets*/
@media (max-width: 420px) {
  .navbar-brand ul li{
     width:100%;
   }
}
