Creating a Custom Login
Before You Start
You can also put together your own login form for PageLime using the code below. However, you first have to set up a CNAME for Pagelime account for this to work properly.
After setting up a CNAME, you can implement the below code. Replacing 'cms.mydomain.com for your custom CNAME address.
The Sample Code
<form id="cmsLoginForm" method="post" action="http://cms.mydomain.com/CMS/Login.ashx">
<input type="hidden" name="cname" value="cms.mydomain.com" />
<div><input type="text" name="email" /> Email</div>
<div><input type="password" name="password" /> password</div>
<input type="submit" />
</form>
By implementing this into your site with a little bit of CSS you can have a nice looking, totally custom log in page for your clients.
