Display some text when the checkbox is checked:
Login Form
Responsive Form
Resize the browser window to see the effect. When the screen is less than 600px wide, make the two columns stack on top of each other instead of next to each other.
Popup Form
Click on the button at the bottom of this page to open the login form.
Note that the button and the form is fixed – they will always be positioned to the bottom of the browser window.
