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);          }
