我已经使用CSS创建了家谱。
家谱树正常工作,但问题是,如果一行中的列表过多,则会中断该行右端的行,并将其显示在新行上。
如何使此族谱水平延伸而不破坏子元素?即使页面底部没有水平滚动条,我也只想按原样显示此树-无需将元素移动到新行中。
这是代码:
.tree ul {
overflow-x: auto;
padding-top: 20px; position: relative;
transition: all 0.5s;
-webkit-transition: all 0.5s;
-moz-transition: all 0.5s;
}
.tree li {
overflow-x: auto;
float: left; text-align: center;
list-style-type: none;
position: relative;
padding: 20px 5px 0 5px;
transition: all 0.5s;
-webkit-transition: all 0.5s;
-moz-transition: all 0.5s;
}
/*We will use ::before and ::after to draw the connectors*/
.tree li::before, .tree li::after{
content: '';
position: absolute; top: 0; right: 50%;
border-top: 1px solid #F39331;
width: 50%; height: 20px;
}
.tree li::after{
right: auto; left: 50%;
border-left: 1px solid #F39331;
}
/*We need to remove left-right connectors from elements without
any siblings*/
.tree li:only-child::after, .tree li:only-child::before {
display: none;
}
/*Remove space from the top of single children*/
.tree li:only-child{ padding-top: 0;}
/*Remove left connector from first child and
right connector from last child*/
.tree li:first-child::before, .tree li:last-child::after{
border: 0 none;
}
/*Adding back the vertical connector to the last nodes*/
.tree li:last-child::before{
border-right: 1px solid #F39331;
border-radius: 0 5px 0 0;
-webkit-border-radius: 0 5px 0 0;
-moz-border-radius: 0 5px 0 0;
}
.tree li:first-child::after{
border-radius: 5px 0 0 0;
-webkit-border-radius: 5px 0 0 0;
-moz-border-radius: 5px 0 0 0;
}
/*Time to add downward connectors from parents*/
.tree ul ul::before{
content: '';
position: absolute; top: 0; left: 50%;
border-left: 1px solid #F39331;
width: 0; height: 20px;
}
.tree li a{
border: 1px solid #0F60AF;
background-color: #0F60AF;
padding: 5px 10px;
text-decoration: none;
color: #fff;
font-family: arial, verdana, tahoma;
font-size: 11px;
display: inline-block;
border-radius: 5px;
-webkit-border-radius: 5px;
-moz-border-radius: 5px;
transition: all 0.5s;
-webkit-transition: all 0.5s;
-moz-transition: all 0.5s;
}
bg_orange {
border: 1px solid #F39331;
background-color: #F39331;
}
/*Time for some hover effects*/
/*We will apply the hover effect the the lineage of the element also*/
.tree li a:hover, .tree li a:hover+ul li a {
background: #F39331; color: #fff; border: 1px solid #F39331;
}
<div class="tree">
<ul>

正在寻求有关如何将其水平延伸的帮助?
谢谢。

在这种情况下,可以通过将display:flex
添加到.tree ul
来使用css-flexbox,这应该可以工作
display: flex;
padding-top: 20px;
position: relative;
transition: all 0.5s;
-webkit-transition: all 0.5s;
-moz-transition: all 0.5s;
您似乎也没有为父width
定义ul
,而是将width:100%
添加到.tree ul
。
