基于CSS3的滑入式导航

问题描述 投票：0回答：2

我正在使用基于CSS3的滑入式导航。导航当前从左到右滑动，并以一定角度进行必要的过渡。我想使用相同的效果，但我需要从右到左发生幻灯片。

我从codepen中找到了这个片段，我尝试对它进行更改，但我无法实现它。

如果有人能为我解决这个问题，那将会有很大的帮助。

这是我的代码快速Fiddle - 

.navigation-menu__bars, .navigation-menu__bars::before, .navigation-menu__bars::after {
  cursor: pointer;
  border-radius: 1px;
  height: 2px;
  width: 25px;
  background: #fff;
  position: absolute;
  left: 0;
  top: 50%;
  display: block;
  transition: all .3s;
}
.navigation-menu {
  background-color: transparent;
  height: 100%;
  position: fixed;
  width: 527px;
  transform: translateX(-100%);
  transition: transform .3s .3s;
}
.navigation-menu::before {
  background: #4E567E;
  content: '';
  height: 400%;
  left: 50%;
  position: absolute;
  top: 0;
  transform: translate(-50%, -50%) rotate(40deg);
  width: 100%;
  z-index: 0;
}
.navigation-menu--open {
  transform: translateX(0);
}
.navigation-menu--open .navigation-menu__bars {
  background-color: transparent;
}
.navigation-menu--open .navigation-menu__bars::before, .navigation-menu--open .navigation-menu__bars::after {
  top: 0;
}
.navigation-menu--open .navigation-menu__bars::before {
  transform: rotate(45deg);
}
.navigation-menu--open .navigation-menu__bars::after {
  transform: rotate(-45deg);
}
.navigation-menu--open .menu-list__item {
  opacity: 1;
  transition-delay: 1.25s;
}
.navigation-menu__toggle {
  cursor: pointer;
  height: 30px;
  position: absolute;
  right: -40px;
  top: 5px;
  width: 30px;
}
.navigation-menu__bars::before, .navigation-menu__bars::after {
  content: '';
}
.navigation-menu__bars::before {
  left: 0;
  top: -8px;
}
.navigation-menu__bars::after {
  left: 0;
  top: 8px;
}

.menu-list {
  padding: 60px 20px;
  position: relative;
  z-index: 10;
}
.menu-list__item {
  margin: 40px 0;
  opacity: 0;
  transition: opacity .5s .5s;
}

您可以在css中使用动画。这是w3school网站上显示的最佳示例。这是您可以使用的动画的最佳示例

<!DOCTYPE html>
<html>
<head>
<style> 
div {
  width: 100px;
  height: 100px;
  background: red;
  position: relative;
  -webkit-animation: myfirst 5s 2; /* Safari 4.0 - 8.0 */
  -webkit-animation-direction: alternate; /* Safari 4.0 - 8.0 */
  animation: myfirst 0.5s;
  animation-direction: ri;
}

/* Safari 4.0 - 8.0 */
@-webkit-keyframes myfirst {
  0%   {background: red; left: 200px; top: 0px;}
  50%  {background: yellow; left: 50px; top: 0px;}
  75% {background:red; left:25px;top:0px;}
  100% {background: red; left: 0px; top: 0px;}
}

</style>
</head>
<body>

<h1>The animation-direction Property</h1>

<p>Play the animation forwards first, then backwards:</p>
<div></div>
<p><strong>Note:</strong> The animation-direction property is not supported in Internet Explorer 9 and earlier versions.</p>

</body>
</html>

经过3个半小时的奋斗，我自己解决了。

(function($) {
  $('.js-nav-menu-toggle').on('click', function() {
    $(this).parents('.navigation-menu').toggleClass('navigation-menu--open');
  });
  
  $('html').on('click', function(e) {
    if(!$(e.target).closest('.js-nav-menu').length &&
      ($('.js-nav-menu').hasClass('navigation-menu--open'))) {
        $('.js-nav-menu').removeClass('navigation-menu--open');
    }
  });
