This article introduces you to the CSS3 effect of moving menu buttons. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.
I need to make a custom animated button effect, but the small front-end doesn’t know how to implement it. I took a look at the desired effect and wrote a simple demo
for him.
The designer gave two pictures, one is a menu icon like 三
, and the other is an icon that turns into X
when clicked. I hope there will be an animation switching effect between these two icons.
Because the icons are very simple, we can use css
to draw these two icons, and then create an animation transition effect. The code is as follows:
html code
<p class="box"> <p class="menu"></p> </p>
The .box
outside is just to hold up the page and has no actual effect. What is useful is a .menu
.
CSS code
.box { margin: 200px; } .menu { width: 100px; height: 100px; position: relative; } .menu:before, .menu:after { content: ""; display: block; width: 100px; height: 16px; background: #000; border-radius: 8px; position: absolute; left: 0; -webkit-transition: all 0.15s ease-in-out; transition: all 0.15s ease-in-out; } .menu:before { top: 5px; box-shadow: 0 37px #000; } .menu:after { bottom: 5px; } .menu:hover:before { top: 42px; box-shadow: none; -webkit-transform: rotate(225deg); transform: rotate(225deg); } .menu:hover:after { bottom: 42px; -webkit-transform: rotate(135deg); transform: rotate(135deg); }
Key explanation:
An element is added transition: all 0.15s ease-in-out;
Code like this , then when any of his attributes change, there will be a switching effect. For more information, please refer to the CSS3 transition attribute
Because there are three horizontal lines, the two pseudo-elements :before
and :after
are not enough. I don't want to add another element to have more things to control. So, I used a box-shadow: 0 37px #000;
shadow method to achieve the effect of the horizontal line in the middle. :before
and :after
are placed above and below respectively.
When switching X
, there are only two elements, I just need to remove the shadow added above box-shadow: none;
.
Then it’s time to change the position and add rotation. Location changes are not indicated. Rotation is implemented using the transform: rotate(225deg);
attribute. For more information, please refer to the CSS3 transform attribute
The final effect is as follows:
Okay, the effect is achieved. I put the above animation on the switch for 3 seconds in order to see the details of the animation clearly.
In fact, after understanding this idea, we can make many simple animation effects.
