Question

出于某些原因，我有一个＆＃34; lime＆＃34; ＆＃34; top＆＃34;之间的彩色1px线以及＆＃34; bod＆＃34;。当我删除overflow css指令时，该行就会消失。

我只能看到＆＃34; lime＆＃34;在Chrome中排队，而不在Firefox中。

Answer 1

将填充从6px更改为5px：

#chatHeaderArrowClassic {
                padding:0;
                margin:0;
                border:0;
                color:#9900ff;
                display:inline-block;
                float:right;
                padding:5px;
                font-size:18px;
            }

Answer 2

它可能来自标题中的两个子元素。 padding使其中一个容器高于容器，其中设置了float导致溢出，因为您没有在那里设置任何clearfix。

但是，由于您将float:right设置为“Top”，只需在“Arr”上设置float:left，并通过在容器上添加overflow:hidden来清除浮动。那条细石灰线将被移除。

Answer 3

您好，

看起来父元素的背景颜色为石灰，如果你隐藏#chatHeaderClassic背景色，它会显示出来.Proof：

var myApp = angular.module('myApp', []);

function MyCtrl($scope) {
  $scope.name = 'Angular Directive';
  $scope.osList = "Original value";
  $scope.stuffFromController = {};
  $scope.myFunc  = function(){ alert("Function in controller");};
};

var HelloDirective = function() {
  return {
    scope: {
      list: "=",
      func: "&"
    }, // use a new isolated scope
    restrict: 'AE',
    replace: false,
    template: '<h3>{{list}}</h3><button ng-click="func()" type="button">Button</button>',
    link: function(scope, elem, attrs) {
      }
  };
};

myApp.directive("helloDirective", HelloDirective);

}

所以只需将上面的代码更改为：

#chatApplicationClassic {
padding: 0;
margin: 0;
border: 0;
position: fixed;
bottom: 0px;
right: 30px;
width: 300px;
background-color: lime;
box-sizing: border-box;
border-radius: 5px 5px 0 0;
box-shadow: 0px 0px 5px #000000;

}

希望这会有所帮助。此致

为什么这些div之间存在垂直差距？
