Stylesheet :
in the page’s HEAD section just add the <style type="text/css"> with the "load {" codes you want the spinner animation to show as, that's all :HTML Markup :
in the page’s Html Markup just add a <div> element with a class name "load#" where you want the spinner animation to appear, that's all :<div class="load#"></div>
The CSS :
the following CSS code will render this spinner loading animation :CSS –Part 1 :
In the first part we will define our spinner style, with CSS3 we can create many shapes, like lines, squares, pies, circles … but also we can generate textures, stripes and other complex patterns.In this case we will use the div borders and assign a radius value equal to the width of each border, and we'll obtain a circle divided by 4. We can color each border to have a nice spinning wheel :
<style> /* Begin Pure CSS Loading Spinner Animations */ /* == This Script Free To Use Providing This Notice Remains == */ /* == This Script Has Been Found In The https://snapbuilder.com Free Public Codes Library == */ .load3 { width:0; height:0; border-right:20px solid #3399ff; border-top:20px solid red; border-left:20px solid yellow; border-bottom:20px solid green; border-radius:20px; -moz-border-radius:20px; -webkit-border-radius:20px; /* Loading Spinner Animation using CSS3 animations */ animation:bganim 0.6s linear 0s infinite; -moz-animation:bganim 0.6s linear 0s infinite; -webkit-animation:bganim 0.6s linear 0s infinite; } </style>
CSS –Part 2 :
The second part is the animation; we have to rotate our div indefinitely, this can be done by using the CSS3 animations to perform a 360° rotation. We can control the direction, speed and the movement style (linear, ease, ...) :/* Animate and rotate the spinner using CSS3 Animations */ animation: bganim 0.6s linear 0s infinite; /* moz: Vendor prefixe for Mozilla Firefox */ -moz-animation:bganim 0.6s linear 0s infinite; /* webkit:Vendor prefixe for Google Chrome, Chromium, Apple Safari... */ -webkit-animation:bganim 0.6s linear 0s infinite; } @keyframes bganim { /* Rotate the div 360° */ from { transform:rotate(0deg); } to { transform:rotate(360deg); } } @-moz-keyframes bganim { from { -moz-transform:rotate(0deg); } to { -moz-transform:rotate(360deg); } } @-webkit-keyframes bganim { from { -webkit-transform:rotate(0deg); } to { -webkit-transform:rotate(360deg); } }As you noticed each line is repeated with "-moz" and "-webkit" prefixes, this is for compatibility reasons for browsers like Mozilla, chrome, safari ...
To change the animation speed change the second part in the "animation:" lines (for example 0.5s : half a second) and to inverse the rotation direction, just switch the "transform:rotate" values : "0deg" and "360deg". Also change linear to ease to have an animation style like the forth spinner in the above running example.
That's all !!!
Other Spinners :
Replace the Part1 CSS code with the following CSS to create the correspondent spinner :<style> /* Begin Pure CSS3 Loading Spinner Animations */ /* == This Script Free To Use Providing This Notice Remains == */ /* == This Script Has Been Found In The http://snapbuilder.com Free Public Codes Library == */ .load1 { height:5px; width:40px; background-color:#000000; /* Loading Spinner Animation using CSS3 animations */ animation:bganim 0.5s linear 0s infinite; -moz-animation:bganim 0.5s linear 0s infinite; -webkit-animation:bganim 0.5s linear 0s infinite; } </style>
<style> /* Begin Pure CSS3 Loading Spinner Animations */ /* == This Script Free To Use Providing This Notice Remains == */ /* == This Script Has Been Found In The https://snapbuilder.com Free Public Codes Library == */ .load2 { /* This is a CSS half cicle */ height:20px; width:40px; border-radius:0 0 90px 90px; -moz-border-radius:0 0 90px 90px; -webkit-border-radius:0 0 90px 90px; background:gray; /* Loading Spinner Animation using CSS3 animations */ animation:bganim 0.5s linear 0s infinite; -moz-animation:bganim 0.5s linear 0s infinite; -webkit-animation:bganim 0.5s linear 0s infinite; } </style>
