Question

有誰知道如何更改CSS和HTML

以便在縮小窗口大小時不會破裂？ 幾天來，我一直在努力尋求動態且響應迅速的HTML / CSS家族樹解決方案。

 /*Now the CSS*/ * { margin: 0; padding: 0; } .tree ul { padding-top: 20px; position: relative; transition: all 0.5s; -webkit-transition: all 0.5s; -moz-transition: all 0.5s; } .tree li { 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 #ccc; width: 50%; height: 20px; } .tree li::after { right: auto; left: 50%; border-left: 1px solid #ccc; } /*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 #ccc; 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 #ccc; width: 0; height: 20px; } .tree li a { border: 1px solid #ccc; padding: 5px 10px; text-decoration: none; color: #666; 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; } /*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: #c8e4f8; color: #000; border: 1px solid #94a0b4; } /*Connector styles on hover*/ .tree li a:hover+ul li::after, .tree li a:hover+ul li::before, .tree li a:hover+ul::before, .tree li a:hover+ul ul::before { border-color: #94a0b4; } /*Thats all. I hope you enjoyed it. Thanks :)*/

您可以嘗試更改填充，邊距和字體大小。 它們都以px為單位，因此它們將在小屏幕上顯示為大，在大屏幕上顯示為小。 您可以嘗試將所有內容更改為以vw和vh（ https://www.w3schools.com/cssref/css_units.asp ）表示，這將有助於其對尺寸更改做出更快的響應
