问题
我正在尝试设计一个用户个人资料栏,在现场,它应该是这样的:
这是我在这里尝试实现的,当点击按钮时。而且会发生什么,菜单没有显示,因为我使用overflow: hidden;
来清除float
。菜单隐藏在里面。
我希望它能够做出响应(好吧,只是在不同的屏幕分辨率和实例中使用width
的百分比),我希望它们以这种方式显示:
有没有更好的方法来实现它?此外,我不确定如何使省略号显示,如果大小太小,请参阅代码段中的mobile
类。
预览
对于那些无法预览片段的用户,它会以这种方式显示:
默认视图。
已点击箭头。
答案 0 :(得分:4)
在这种情况下,您需要使用position
ing。这是固定流体模型:
+-------+-----------+
| FIXED | FLUUUUUID |
+-------+-----------+
或者
+-------+-----------+
| FIXED | FLUUUUUID |
| | FLUUUUUID |
+-------+-----------+
要解决此问题,您需要将fixed
内容定位absolute
,我想,作为固定内容,您一定会知道尺寸。并为父级position: relative
以及这些维度的padding-left
和min-height
提供帮助。在这种情况下,您应该从不使用overflow: hidden
或float
。因此,从CSS中删除它们并进行这些更改:
.user-profile {border: 1px solid #999; position: relative; margin: 25px 0;} /* Remove overflow: hidden; */
.user-profile .user-thumb {border: 1px solid #999; margin: 5px; padding: 3px; border-radius: 3px;} /* Remove float: left; */
相反,如前所述,为父级添加padding
,min-height
,为子级添加position: absolute
:
.user-profile {border: 1px solid #999; position: relative; margin: 25px 0; padding-left: 68px; min-height: 68px;}
.user-profile .user-thumb {border: 1px solid #999; margin: 5px; padding: 3px; border-radius: 3px; position: absolute; top: 0; left: 0;}
神秘的68px
:
68px
通过以下方式计算:
5px
1px
3px
50px
3px
1px
5px
所以,5px + 1px + 3px + 50px + 3px + 1px + 5px = 68px
。
文字省略号
要使省略号适用于主流浏览器,您可以使用以下代码:
(selector) {
white-space: nowrap;
overflow: hidden;
text-overflow: ellipsis;
}
只需将其添加到.user-profile p
规则:
.user-profile p {white-space: nowrap; overflow: hidden; text-overflow: ellipsis;}
此外,最好让z-index
项position: absolute
与其他类似项目配合使用。所以请添加:
.user-profile .more-options-list {position: absolute; right: 0; top: 70px; border: 1px solid #999; width: 100px; display: none; background-color: #fff; z-index: 1;}
所以,最终的代码是:
$(function () {
$(".more-options").click(function () {
$(this).closest(".user-profile").toggleClass("open");
return false;
});
});
/* Reset */
* {margin: 0; padding: 0; list-style: none; font-size: 12pt;}
a {text-decoration: none;}
/* Main CSS */
.user-profile {border: 1px solid #999; position: relative; margin: 25px 0; padding-left: 68px; min-height: 68px;}
.user-profile .user-thumb {border: 1px solid #999; margin: 5px; padding: 3px; border-radius: 3px; position: absolute; top: 0; left: 0;}
.user-profile p {white-space: nowrap; overflow: hidden; text-overflow: ellipsis;}
.user-profile p:first-child {margin: 3px 0 0;}
.user-profile .more-options {position: absolute; right: 0; top: 0; height: 100%; width: 30px; background: center center no-repeat #ccc; text-indent: -99px; overflow: hidden;}
.user-profile .more-options-list {position: absolute; right: 0; top: 70px; border: 1px solid #999; width: 100px; display: none; background-color: #fff; z-index: 1;}

这是菜单打开和不打开时的显示方式。

答案 1 :(得分:1)
问题是你不想隐藏溢出,你想建立一个块格式化上下文。是的,overflow: hidden
建立了一个BFC作为副作用,但这只是一个黑客。在CSS2.1中还有其他建立BFC的方法,但都有自己的问题,比如取出流量,变成内联级别,......
显示L3引入了建立BFC的正确方法:
display: flow-root;
但是浏览器还不支持它。所以同时,我建议清除黑客:
.wrapper::after {
content: '';
clear: both;
display: block;
}
$(function () {
$(".more-options").click(function () {
$(this).closest(".user-profile").toggleClass("open");
return false;
});
});
.user-profile:after {
content: '';
clear: both;
display: block;
}
