Create a full screen Navigation Bar: In this article, you will learn how to create a full-screen navbar for your website. There are three methods to create a full screen overlay navigation bar which are listed below:
- From Left
- From top
- No animation- Just show
You will be required to create two divs. One for the overlay container and the other for the overlay content container.
Step 1: The first step is to create an HTML file.
< div id = "myNav" class = "overlay" >       <!-- Button to close the overlay navigation -->     < a href = "javascript:void(0)" class = "closebtn"         onclick = "closeNav()" >×     </ a >       <!-- Overlay content -->     < div class = "overlay-content" >         < a href = "#" >About</ a >         < a href = "#" >Services</ a >         < a href = "#" >Clients</ a >         < a href = "#" >Contact</ a >     </ div > </ div >   <!-- Use any element to open/show the     overlay navigation menu --> < span onclick = "openNav()" >open</ span ></ div > |
Step 2: Add CSS to the file.
<style>     overlay {         height : 100% ;         width : 0 ;         position : fixed ;         ] z-index : 1 ;         left : 0 ;         top : 0 ;         background-color : rgb ( 0 , 0 , 0 );         background-color : rgba( 0 , 0 , 0 , 0.9 );         overflow-x: hidden ;         transition: 0.5 s;     }       ].overlay-content {         position : relative ;         top : 25% ;         width : 100% ;         text-align : center ;         margin-top : 30px ;     }       .overlay a {         padding : 8px ;         text-decoration : none ;         font-size : 36px ;         color : #818181 ;               /* Display block instead             of inline */         display : block ;                   /* Transition effects             on hover (color) */         transition: 0.3 s;     }       .overlay a:hover,     .overlay a:focus {         color : #f1f1f1 ;     }       .overlay .closebtn {         position : absolute ;         top : 20px ;         right : 45px ;         font-size : 60px ;     }       @media screen and ( max-height : 450px ) {         .overlay a {             font-size : 20px         }           .overlay .closebtn {             font-size : 40px ;             top : 15px ;             right : 35px ;         }     } </style> |
Step 3: In the final step add JavaScript to the files.
<script>     function openNav() {         document.getElementById( "myNav" ).style.width = "100%" ;     }       function closeNav() {         document.getElementById( "myNav" ).style.width = "0%" ;     }       //or       function openNav() {         document.getElementById( "myNav" ).style.display = "block" ;     }       function closeNav() {         document.getElementById( "myNav" ).style.display = "none" ;     } </script> |
Example 1: This example creating the Full Screen Overlay Navigation Bar from left.
<!DOCTYPE html> < html >   < head >     < meta name = "viewport" content=" width = device -width,                initial-scale = 1 ">     < style >         .overlay {             height: 100%;             width: 0;             position: fixed;             top: 0;             left: 0;             background-color: #1a6e1a;             overflow-x: hidden;             transition: 1.0s;         }           .overlay-content {             position: relative;             top: 25%;             width: 100%;             text-align: center;         }           .overlay a {             padding: 10px;             text-decoration: none;             font-size: 40px;             color: white;             display: block;             transition: 0.3s;         }           .overlay a:hover,         .overlay a:focus {             color: black;         }           .overlay .closebtn {             position: absolute;             top: 10px;             right: 35px;             font-size: 70px;         }     </ style > </ head >   < body >       < div id = "myNav" class = "overlay" >         < a href = "javascript:void(0)"              class = "closebtn" onclick = "closeNav()" >             ×         </ a >         < div class = "overlay-content" >             < a href = "#" >About</ a >             < a href = "#" >Practice</ a >             < a href = "#" >Courses</ a >             < a href = "#" >Contact</ a >         </ div >     </ div >       < span style = "font-size:35px;cursor:pointer"         onclick = "openNav()" >         ≡     </ span >       < h2 >GeeksForGeeks</ h2 >       < p >         Click on the nav bar icon         to see full screen overlay:     </ p >       < script >         function openNav() {             document.getElementById(                 "myNav").style.width = "100%";         }           function closeNav() {             document.getElementById(                 "myNav").style.width = "0%";         }     </ script > </ body >   </ html > |
