带有网格模板区域的网格显示中的过渡持续时间:如何使其工作? [英] Transition duration in grid display with grid-template-areas : how to make it work?
问题描述
当我单击按钮时,我将布局的网格模板从更改为
when I click on button I changed the grid template of my layout from
#chatContainer {
display: grid;
width: 100%;
height: 100%;
grid-template-areas:
"header header header header"
"chat chat chat users"
"footer footer footer footer";
grid-template-columns: 1fr 1fr 1fr 350px;
grid-template-rows: 80px 1fr 80px;
}
到
#chatContainer.resized {
grid-template-areas:
"header header header header"
"chat chat chat chat"
"footer footer footer footer";
grid-template-columns: 1fr 1fr 1fr 350px;
transition-duration: 2s;
}
(我让用户部分消失了)
(I make the users part disappear)
但是过渡持续时间完全没有效果.
But The transition duration has no effect at all.
更改网格模板区域时是否可以添加一些动画/过渡效果?
Is it possible to add some animation/transition effect when changing the grid-template-areas ?
推荐答案
根据需要的值,可以更改过渡事件以使分频平滑,这是您选择的设置网格方式所无法实现的.
As you need values the transition-event can change to make the crossover smooth that is not possible by your choosed way to setup the grid.
但是,如果您仅更改网格的设置,则可能.您只需使用百分比值
,而不是使用 grid-template-areas
设置网格.
But it is possible if you just change your setup of the grid. You only need to use percentage values
instead of setting your grid up with grid-template-areas
.
注意:
- 简化示例只是为了说明/演示技术.
- 已将过渡添加到悬停事件中,而不是按钮技术(=添加一个类)".但是像在项目中一样添加类也应该可以.
- 也可以使用
fr
代替%
作为值. - 在示例中,边界阻止网格区域完全消失.如果这是您遇到的问题,则将网格容器仅用作网格容器(= grid-elements),然后将样式添加到内部content-div-container(=在其中添加所需的边框).
查看示例:
* {
box-sizing: border-box;
}
.grid-wrapper {
display: grid;
width: 100%;
height: 100px;
grid-template-columns: 75% 25%;
transition: all 2s;
}
.grid-wrapper > div {
border: 1px solid magenta;
overflow-x: hidden;
}
.chat {
background: yellow;
}
.user {
background: orange;
overflow: hidden;
}
.grid-wrapper:hover {
grid-template-columns: 100% 0%;
transition: all 2s;
}
<h2>Hover it to see how technique works:</h2>
<div class="grid-wrapper">
<div class="chat">Chat</div>
<div class="user">User</div>
</div>
