All in One is an HTML Template. To customize this template, You should know some basic HTML and Computer Knowledge. If you don't have this knowledge, Please see the builder docs, to know how you can customize this template without HTML knowledge.
You can customize this template with any Code editing software. I recommend Dreamweaver or Sublime Text. But, you can even customize the template with Notepad. So don't worry if you don't have these software.
Version 2.0 comes with HTML Page Builder. It will allow you to customize this Template directly on your browser without touching any piece of code. Please refer to the Builder Docs in the documentation folder to know how to make it work.
To change the current logo to your Logo, Create it separately in any Graphic software and Export it in PNG format, so that the background will be transparent.
Once you've created the logo, copy it to HTML/images folder. Then link it in the Logo section in HTML file.
Eg:
<img src="images/NAME_OF_YOUR_LOGO.png" alt="all-in-one-logo"></a>
The template comes with a working contact form, so that your users can contact you directly to your email. Even in mobile.To configure contact form, first open /contact.php file there you can see my email id, change it to yours. Now upload it to a PHP Server (with SMTP Support) . Boom!! Your contact form will work perfectly.
If you need to redirect your users to a thank you page once the user successfully entered the form, There is an easy way for that. If you look at the form in HTML code, You can see the following code.
<form class="form" id="phpcontactform" data-redirect="thank-you.html">
The data-redirect attribute will do the trick. Just change the URL to your Thank you HTML page. and the users will be automatically redirect to that page. If you want to stay on the same page, Please change the URL to none.
From v2.1, This template includes Exit intent Popup. Now convert your leaving visitors to your paying customers. This script uses Exit Intent technology, where it will open an a Popup for the visitor who is about to leave. Then you can show some Special offer or Extra Discount on that popup for a better conversion.
Exit Popup is icluded in base.html and exit-popup.html. In order to activate Exit popup, Please add data-exit-popup="true" to the <body> tag. To edit content, scroll to very bottom of the HTML and find :Exit Intent Popup: section. Then you can customize the content. Also make sure you have referenced /js/exitpopup.js in the footer. If you want to change some advaced options, head over to /js/script.js See Pluigin Docs for more info.
