定时滑动文本框

Question

I'm looking for a way to animate my text box so that it slides into frame from the right side at (x) amount of time. So far, I haven't found any online resources that could help me with this animation.

For now, I just have a simple (absolute) box.

 .taskbox { width: 230px; padding: 15px; position: absolute; right: 25px; top: 25px; background-color: black; color: white; font-family: courier new; font-size: 20px; }

 <div class="taskbox">Evidently, the pandemic has taken a toll on the economy. You should find a way to financially stay afloat. Humans have something called 'stipends' to aide in a situation like this. We should <a href="a2_page_3.html">investigate</a>!</div>

Note: Not too sure if this will require JavaScript, but I have preexisting functions for elements not involved in my question. If my script is needed, I'm more than happy to update my post.

Thanks in advance for your help!

This can be done with CSS only with animation you can specify a duration as well as a delay (in your case x). Paradoxically to make an element slide from the right it easier to positioned it with the left property. Like so…

 .taskbox { width: 230px; padding: 15px; left: 100%; position: absolute; top: 25px; background-color: black; color: white; font-family: courier new; font-size: 20px; animation: slide-from-right.4s 2s forwards; /* x = 2s */ } @keyframes slide-from-right { to { left: calc(100% - 230px - 30px - 25px); /* 100% = total width, 230px = element width, 30px = left and right padding, 25px = distance from right border */ } }

 <div class="taskbox">Evidently, the pandemic has taken a toll on the economy. You should find a way to financially stay afloat. Humans have something called 'stipends' to aide in a situation like this. We should <a href="a2_page_3.html">investigate</a>!</div>

You could animate transform: translate :

 .taskbox { width: 230px; padding: 15px; position: absolute; right: 25px; top: 25px; background-color: black; color: white; font-family: courier new; font-size: 20px; transform: translate3d(calc(100% + 25px), 0, 0); animation: slide-in 0.5s 1s cubic-bezier(0.3, 1.3, 0.9, 1) forwards; } @keyframes slide-in { to { transform: translate3d(0, 0, 0); } }

 <div class="taskbox">Evidently, the pandemic has taken a toll on the economy. You should find a way to financially stay afloat. Humans have something called 'stipends' to aide in a situation like this. We should <a href="a2_page_3.html">investigate</a>!</div>

In case you're wondering why I'm using translate3d , it triggers hardware acceleration. Check out this article if you're interested .
