Let’s considera simple script that after a while displays this button on your landing page:

When you click the button, the application submission form is displayed:

To install this script, move the callbacker folder to the main folder where your landing page is located.
Next, open the index file of your landing page and connect the js and css files (it’s best to insert them before the closing head tag):
<link type=»text/css» rel=»stylesheet» href=»callbacker/css/css.css» />
<script type=»text/javascript» src=»callbacker/js/script.js»></script>
If landing page does not have the jquery library, include it by inserting the following text also before the closing head tag:
<script src=»https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js»></script>
If you want to increase the appearance time of the button or decrease it, then you need to open the script.js file and there will be a footnote describing where to change it.
Well, after all these manipulations, in order to insert the block itself with the form and button, you need to copy the code wrapped in the archive from the index.html file
<!— <callbacker> —>
<!— </callbacker> —>
and place it before the closing body tag.
P.S. Give it a thumbs up and don’t forget to set up the lead submission form itself (and send a donation, of course)!
