There are two main animation effects. One is when the mouse is hovering The situation when the lighter lid is opened when "hover me" is implemented by the following animation code:
<span style="font-family:Comic Sans MS;font-size:12px;">@-webkit-keyframes lidoff{ 注意这里要加上-webkit-
from{
transform:rotate(0deg);
transform-origin:100% 100%;
}
to{
transform:rotate(130deg);
transform-origin:100% 100%;
}
}
</span> The second animation is the realization of the candle lighting effect: the candle is controlled by the transition variable :opacity 3s linear; Realized,
The effect of the candle light swinging in the wind is achieved by the following code:
<span style="font-family:Comic Sans MS;font-size:12px;">@-webkit-keyframes lidoff{
from{
transform:rotate(0deg);
transform-origin:100% 100%;
}
to{
transform:rotate(130deg);
transform-origin:100% 100%;
}
</span> The effect of separating the lighter cover from the torso It is implemented by: box-shadow:inset 0 0 5px 5px #333; Mainly the inset here (be careful not to write it as insert).
The round ball and small white square that appear when the lighter is turned on are the effects achieved by :after :before combined with z-index.
The following will introduce some attributes that I learned through this example and need to pay attention to.
transform-origin: The default initial position is the center of the image, 100% 100% is equivalent to right bottom. 0% 0% is equivalent to left top.
before and :after : The injected content is a child element of the associated target element, but it will be placed "before" any content of this element or "after". The inserted content is invisible in the source code of the page and can only be seen in the css. Elements inserted at the same time are inline elements by default. Therefore, in order to give an inserted element height, padding, margins, etc., a block-level element (display:block) must usually be explicitly defined.
In addition, although no content may be inserted, content must be written. If no content is inserted, then content is written as content:"";
IE6 and IE7 is not compatible with these two elements. They are
pseudo elements (double colon), and the pseudo class in css3 is (single colon)
animation -fill-mode: none|forwards|backwards|both|initial|inherit;
Specifies that when the animation does not play (when the animation completes, or when the animation has a delay and does not start playing), it should be applied to The style of the element.
background-image: Solve the problem that p can only set one background, so that one p can set multiple background images.
box-shadow: An often forgotten parameter--spread (expanded shadow radius), this once-forgotten spread changes the size of the shadow---its value can be positive or negative, if the value is positive , the entire shadow will expand and expand, otherwise it will shrink if it is a negative value. With this parameter, you can use box-shadow to create a single-sided shadow effect like shadow work in photoshop. One thing to note here is that this extended shadow value needs to be used in conjunction with the shadow blur radius. The general situation is that "the extended shadow radius is generally set to be equal to the blur radius, and its negative values are removed."
The above is the entire content of this article. I hope it will be helpful to everyone's learning, and I also hope that everyone will support the PHP Chinese website.
