使 div 处于活动状态而不单击其中的某个位置 [英] Make a div active without clicking somewhere in it
问题描述
我在我构建的页面上使用水平滚动.它在一个 div 内，用一个类命名，我想使用箭头键来滚动.为了让它随键滚动，我需要点击它的某个地方.
是否可以在第一次加载页面时直接使用这些键而不必点击它?
如果可能的话，我需要方向键直接起作用并在该特定 div 内开始水平滚动.
.scroll { grid-template-columns: repeat(15,1fr);溢出-x:滚动；滚动快照类型:x 接近度；}<div class="容器"><img src="ok.png"><div class="inmiddle"><div class="描述">blablabla
</div></li></ul>
如果你可以使用这个简单的 JS:
document.getElementById('scroll').focus();<div id="滚动">例子否则将伪类 :active 添加到您的 div.
您也可以根据需要更改此伪类的属性.
I use a horizontal scroll on a page I built. It's inside a div, named it with a class, and I want to use the arrows keys to scroll. For it to scroll with the keys, I need to click somewhere on it.
Is it possible to use the keys directly on first load of the page without necessarily clicking it?
I need the arrow keys to be functional directly and start the horizontal scroll inside that particular div, if that's possible.
.scroll { grid-template-columns: repeat(15,1fr); overflow-x: scroll; scroll-snap-type: x proximity; }
<ul class="scroll"> <div class="container"> <img src="ok.png"> <div class="inmiddle"> <div class="description"> blablabla</div> </div> </div></li></ul>
If you can just use this simple JS:
document.getElementById('scroll').focus();
<body>
<div id="scroll">
example
</div>
</body>
Otherwise add the pseudo class :active to your div.
You can also change the properties to this pseudo class as you need.
