z-index仍然在我的汉堡包图标上工作

时间：2018-01-31 00:45:47

标签： css css3 z-index

在使用忘记添加x属性的z-index之前，我犯了错误。我的display汉堡图标并未显示所有其他元素。

我已将#brgr设置为100，高于任何其他元素。

我的标题怎么样？

＆＃13;
＆＃13; 
z-index
＆＃13; 
// Navigation
function initNav() {
	// Main
	const $menuTrigger = $('button#brgr');
	const $menuArea = $('#menu');
	// Content
		var $menuExpanded = false;
		 $menuTrigger.on('click', function(){
			if (!$menuExpanded) {
				$menuArea.addClass('is-out');
					$menuExpanded = true;
			} else {
				$menuArea.removeClass('is-out');
					$menuExpanded = false	
			}
		});
}
    
$(document).ready(function() {

initNav();

z-index
// Navigation

	const $menuArea = $('#menu');
	// Content
		var $menuExpanded = false;

				$menuArea.addClass('is-out');
					$menuExpanded = true;
			} else {
				$menuArea.removeClass('is-out');
					$menuExpanded = false	
			}
		});
}
    
$(document).ready(function() {

initNav();

});
button {
  background: 0;
  border: 0;
  cursor: pointer;
}

#menu {

  right:calc( -100vw - -59.3%);
  top:0;
  bottom: 0;
  background: blue;
  transition: 200ms all ease;
  z-index:10;
}

#menu.is-out {
  right: 0
}

header {
  width: 100%;
  padding: 40px 0 20px;
  background: #fff;
  position: fixed;
  z-index: 9;
} 

  header a.logo {
    max-width: 175px;
    position: relative;
    float: left;
  }

  header #brgr {
    width: 35px;
    height: auto;
    float: right;
    position: absolute;
    z-index: 100;
  }

    header #brgr span {
      display: block;
      background: #2d2d2d;
      height: 2px;
      margin-bottom: 4px;
      width: auto;
    }

    header #brgr:hover span {
      background: grey
    }

header .wrapper {
  padding-left: 30px;
  padding-right: 30px
}

我会移动#menu元素内的header，因为您可能会在滚动时将标题粘贴到页面顶部（可能处于响应模式？！），然后您可以设置较高的z-index属性，以使其始终可见。

// Navigation
function initNav() {
	// Main
	const $menuTrigger = $('button#brgr');
	const $menuArea = $('#menu');
	// Content
		var $menuExpanded = false;
		 $menuTrigger.on('click', function(){
			if (!$menuExpanded) {
				$menuArea.addClass('is-out');
					$menuExpanded = true;
			} else {
				$menuArea.removeClass('is-out');
					$menuExpanded = false	
			}
		});
}
    
$(document).ready(function() {

initNav();

});
button {
  background: 0;
  border: 0;
  cursor: pointer;
}

#menu {
  position:fixed;
  width:calc( 100vw - 59.3%);
  right:calc( -100vw - -59.3%);
  top:0;
  bottom: 0;
  background: blue;
  transition: 200ms all ease;
  z-index:10;
}

#menu.is-out {
  right: 0
}

header {
  width: 100%;
  padding: 40px 0 20px;
  background: #fff;
  position: fixed;
  z-index: 9;
} 

  header a.logo {
    max-width: 175px;
    position: relative;
    float: left;
  }

  header #brgr {
    width: 35px;
    height: auto;
    float: right;
    position: relative;
    z-index: 100;
  }

    header #brgr span {
      display: block;
      background: #2d2d2d;
      height: 2px;
      margin-bottom: 4px;
      width: auto;
    }

    header #brgr:hover span {
      background: grey
    }

header .wrapper {
  padding-left: 30px;
  padding-right: 30px
}
