Using CSS3 to achieve several common Loading effects, although it is very simple, I still share it, and take notes by the way...
The first effect:
The code is as follows:
<p class="loading"> <span></span> <span></span> <span></span> <span></span> <span></span> </p>
.loading{ width: 80px; height: 40px; margin: 0 auto; margin-top:100px; } .loading span{ display: inline-block; width: 8px; height: 100%; border-radius: 4px; background: lightgreen; -webkit-animation: load 1s ease infinite; } @-webkit-keyframes load{ 0%,100%{ height: 40px; background: lightgreen; } 50%{ height: 70px; margin: -15px 0; background: lightblue; } } .loading span:nth-child(2){ -webkit-animation-delay:0.2s; } .loading span:nth-child(3){ -webkit-animation-delay:0.4s; } .loading span:nth-child(4){ -webkit-animation-delay:0.6s; } .loading span:nth-child(5){ -webkit-animation-delay:0.8s; }
The second effect:
The code is as follows:
<p class="loading"> <span></span> </p>
.loading{ width: 150px; height: 4px; border-radius: 2px; margin: 0 auto; margin-top:100px; position: relative; background: lightgreen; -webkit-animation: changeBgColor 1.04s ease-in infinite alternate; } .loading span{ display: inline-block; width: 16px; height: 16px; border-radius: 50%; background: lightgreen; position: absolute; margin-top: -7px; margin-left:-8px; -webkit-animation: changePosition 1.04s ease-in infinite alternate; } @-webkit-keyframes changeBgColor{ 0%{ background: lightgreen; } 100%{ background: lightblue; } } @-webkit-keyframes changePosition{ 0%{ background: lightgreen; } 100%{ margin-left: 142px; background: lightblue; } }
##The 3rd to 5th effects:
##The code is as follows:
<p class="loading"> <span></span> <span></span> <span></span> <span></span> <span></span> </p>
The css styles of the 3rd to 5th effects are:
.loading{ width: 150px; height: 15px; margin: 0 auto; position: relative; margin-top:100px; } .loading span{ position: absolute; width: 15px; height: 100%; border-radius: 50%; background: lightgreen; -webkit-animation: load 1.04s ease-in infinite alternate; } @-webkit-keyframes load{ 0%{ opacity: 1; -webkit-transform: translate(0px); } 100%{ opacity: 0.2; -webkit-transform: translate(150px); } } .loading span:nth-child(1){ -webkit-animation-delay:0.13s; } .loading span:nth-child(2){ -webkit-animation-delay:0.26s; } .loading span:nth-child(3){ -webkit-animation-delay:0.39s; } .loading span:nth-child(4){ -webkit-animation-delay:0.52s; } .loading span:nth-child(5){ -webkit-animation-delay:0.65s; }
##The 6th to 8th effects:
The code is as follows:
<p class="loading"> <span></span> <span></span> <span></span> <span></span> <span></span> </p>
#6 -The css styles of the 8 effects are:
.loading{ width: 150px; height: 15px; margin: 0 auto; margin-top:100px; text-align: center; } .loading span{ display: inline-block; width: 15px; height: 100%; margin-right: 5px; background: lightgreen; -webkit-animation: load 1.04s ease infinite; } .loading span:last-child{ margin-right: 0px; } @-webkit-keyframes load{ 0%{ opacity: 1; } 100%{ opacity: 0; } } .loading span:nth-child(1){ -webkit-animation-delay:0.13s; } .loading span:nth-child(2){ -webkit-animation-delay:0.26s; } .loading span:nth-child(3){ -webkit-animation-delay:0.39s; } .loading span:nth-child(4){ -webkit-animation-delay:0.52s; } .loading span:nth-child(5){ -webkit-animation-delay:0.65s; }
The 9th-10th effects:
The code is as follows:
<p class="loadEffect"> <span></span> <span></span> <span></span> <span></span> <span></span> <span></span> <span></span> <span></span> </p>
The CSS styles are:
.loadEffect{ width: 100px; height: 100px; position: relative; margin: 0 auto; margin-top:100px; } .loadEffect span{ display: inline-block; width: 16px; height: 16px; border-radius: 50%; background: lightgreen; position: absolute; -webkit-animation: load 1.04s ease infinite; } @-webkit-keyframes load{ 0%{ opacity: 1; } 100%{ opacity: 0.2; } } .loadEffect span:nth-child(1){ left: 0; top: 50%; margin-top:-8px; -webkit-animation-delay:0.13s; } .loadEffect span:nth-child(2){ left: 14px; top: 14px; -webkit-animation-delay:0.26s; } .loadEffect span:nth-child(3){ left: 50%; top: 0; margin-left: -8px; -webkit-animation-delay:0.39s; } .loadEffect span:nth-child(4){ top: 14px; rightright:14px; -webkit-animation-delay:0.52s; } .loadEffect span:nth-child(5){ rightright: 0; top: 50%; margin-top:-8px; -webkit-animation-delay:0.65s; } .loadEffect span:nth-child(6){ rightright: 14px; bottombottom:14px; -webkit-animation-delay:0.78s; } .loadEffect span:nth-child(7){ bottombottom: 0; left: 50%; margin-left: -8px; -webkit-animation-delay:0.91s; } .loadEffect span:nth-child(8){ bottombottom: 14px; left: 14px; -webkit-animation-delay:1.04s; }
PS: There are actually a lot of repetitions in the CSS style codes, mainly because the animations are different, but for the convenience of using them directly in the future, I won’t sort them out now.
