Well, for sites that have a login option I'm sure there will also be a password recovery page, but for some wapmasters it becomes difficult to configure and style the page due to not having access to it, but there are classes and tags that you can change with the css, let's go to it.
The image below is simple, without changing anything.
The phrase "Lost Password?" is a DIV with class "menu".
The form is inside a DIV with the class "list".
The error or success notification is a "font" tag.
I'll give an example below with a basic stylization, it can be improved further. Copy this css code to your site stylesheet.
*{
margin:0
}
.menu{
font-weight: bold;
padding:8px 16px;
border-bottom:1px solid #ccc;
font-size:18px
}
.list{
padding:8px 16px
}
.list input[type=text]{
width:100%;
border-radius:4px;
border:1px solid #ddd;
padding:8px 12px;
margin-bottom:16px
}
.list input[type=submit]{
display:inline-block;
border:none;
border-radius:4px;
background:#3699ff;
color:#fff;
padding:8px 16px;
font-weight: bold;
text-transform:capitalize
}
.menu + font{
display:block;
background:#ffdddd;
padding:8px 16px
}
See the result
