반응형 하단 탐색

CSS와 JavaScript를 사용하여 반응형 하단 탐색 메뉴를 만드는 방법을 알아보자.

반응형 하단 Navbar 만들기

1단계) HTML 추가

<div class="navbar" id="myNavbar">
  <a href="#home">Home</a>
  <a href="#news">News</a>
  <a href="#contact">Contact</a>
  <a href="#about">About</a>
  <a href="javascript:void(0);" class="icon" onclick="myFunction()">☰</a>
</div>

 
class=”icon”인 링크는 작은 화면에서 탐색 표시줄을 열고 닫는 데 사용된다.

2단계) CSS 추가

/* Place the navbar at the bottom of the page, and make it stick */
.navbar {
  background-color: #333;
  overflow: hidden;
  position: fixed;
  bottom: 0;
  width: 100%;
}

/* Style the links inside the navigation bar */
.navbar a {
  float: left;
  display: block;
  color: #f2f2f2;
  text-align: center;
  padding: 14px 16px;
  text-decoration: none;
  font-size: 17px;
}

/* Change the color of links on hover */
.navbar a:hover {
  background-color: #ddd;
  color: black;
}

/* Add a green background color to the active link */
.navbar a.active {
  background-color: #04AA6D;
  color: white;
}

/* Hide the link that should open and close the navbar on small screens */
.navbar .icon {
  display: none;
}

/* When the screen is less than 600 pixels wide, hide all links, except for the first one ("Home"). Show the link that contains should open and close the navbar (.icon) */
@media screen and (max-width: 600px) {
  .navbar a:not(:first-child) {display: none;}
  .navbar a.icon {
    float: right;
    display: block;
  }
}

/* The "responsive" class is added to the navbar with JavaScript when the user clicks on the icon. This class makes the navbar look good on small screens (display the links vertically instead of horizontally) */
@media screen and (max-width: 600px) {
  .navbar.responsive a.icon {
    position: absolute;
    right: 0;
    bottom: 0;
  }
  .navbar.responsive a {
    float: none;
    display: block;
    text-align: left;
  }
}

  if (x.className === "navbar") {
    x.className += " responsive";
  } else {
    x.className = "navbar";
