We are witnesses of the flood of responsive web sites. Those sites are made to be useful on all kind of devices, from desktop computers to mobile phones. It's not enough to have only a template that's responsible. If you are about to use modules on the responsive website, those modules should be responsive as well. Hot Film Tape is responsive Joomla module because it supports the responsive websites. This module automatically resizes itself in order to fit the available screen space as good as possible.
So, what Hot Film Tape does and what's its purpose for your site. Let's explain that in several sentences. This is an endless carousel that scrolls slides from right to left. You can have up to 20 slides (it easy to modify the module to extend it's capacity though) and each slide is presented as a "slot" in the module parameters. Each slot can contain any HTML content that you enter using WYSIWYG editor (such as JCE or TinyMCE) or using plain text editor (if you are familiar with HTML). Therefore, each slot can contain literally anything you can think of. You can put text, images, YouTube movies or anything else inside the slides. You can even make combination, in example, the first slot with text, the second with image, the third with a movie and the fourth with text and images. The content of the Hot Film Tape is completely up to you.
In this example, the container of the module has width set to 100%, so it occupies the full screen. If you are using this module with another template, make sure the container where you put the module has the similar settings. But it's not necessary because this module can occupy only a part of your site's space. One more feature that makes this module very flexible.
Please spend some time experimenting with Hot Film Tape. You can also have multiple instances of the module on screen, just make sure that you entered different unique IDs in parameters.
