If you're building a website for fitness trainer (such as what we're doing for RYSTRENGTH), makeup artist, construction, car repair, etc..
Here's what we will be creating.
Table of Contents
Prepare Your Images
Add The Before-After JavaScript
<script type="text/javascript" src="https://cdn.jotfor.ms/before-after/before-after.min.js"> </script>
Then move to the JavaScript section, and add this jQuery code:
jQuery(document).ready(function($) {
jQuery('.ba-slider').beforeAfter();
});
Add CSS
.ba-slider {
position: relative;
overflow: hidden;
}
.ba-slider img {
width: 100%;
display:block;
max-width:none;
}
.ba-slider .resize {
position: absolute;
top:0;
left: 0;
height: 100%;
width: 50%;
overflow: hidden;
}
.ba-slider .handle {
position:absolute;
left:50%;
top:0;
bottom:0;
width:4px;
margin-left:-2px;
background: #ffffff;
cursor: ew-resize;
}
.ba-slider .handle:after {
position: absolute;
top: 50%;
width: 50px;
height: 50px;
margin: -32px 0 0 -24px;
content: '\2194';
color: black;
font-size: 28px;
text-align: center;
background: #ffffff;
border-radius: 50%;
}
Create The First Div
And rename it baslider div
Add your first image (the before image) inside baslider div.
Create the Second Div
Assign the class to it resize.
Rename it as resize div.
Add your second image (the after image) inside resize div.
refer to image above for the structure.
Create the Slider Handler
This goes under the main div (baslider div)
And now you have a before & after slider in Oxygen, without plugins or bloat.
P.S Your slider mgiht look like this image below, that's ok. On the front end it renders perfectly fine.
