各种动效收集

一、<a>标签锚点点击滑动到对应位置（基于jq）

$(‘a[href*=#],area[href*=#]‘).click(function() {
        console.log(this.pathname)
        if (location.pathname.replace(/^\//, ‘‘) == this.pathname.replace(/^\//, ‘‘) && location.hostname == this.hostname) {
            var $target = $(this.hash);
            $target = $target.length && $target || $(‘[name=‘ + this.hash.slice(1) + ‘]‘);
            if ($target.length) {
                var targetOffset = $target.offset().top-50;
                $(‘html,body‘).animate({
                            scrollTop: targetOffset
                        },
                        1000);
                return false;
            }
        }
    }); 

二、图片呼吸动态效果（CSS3）

定义效果：

@mixin animation( $name, $duration, $timing, $delay, $count ) {
animation-name: $name;
animation-duration: $duration;
animation-timing-function: $timing;
animation-delay: $delay;
animation-iteration-count: $count;
-webkit-animation-name: $name;
-webkit-animation-duration: $duration;
-webkit-animation-timing-function: $timing;
-webkit-animation-delay: $delay;
-webkit-animation-iteration-count: $count;
}

@keyframes breath {
0% {
transform: scale(1);
-webkit-transform: scale(1);
}
50% {
transform: scale(1.5);
-webkit-transform: scale(1.5);
}
100% {
transform: scale(1);
-webkit-transform: scale(1);
}
}

@-webkit-keyframes breath {
0% {
transform: scale(1);
-webkit-transform: scale(1);
}
50% {
transform: scale(1.5);
-webkit-transform: scale(1.5);
}
100% {
transform: scale(1);
-webkit-transform: scale(1);
}
}

在需要该效果的地方引用该CSS

          img{
            width: 100%;
            @include animation(breath, 2s, linear, 0s, infinite);
          }
