Joomla is one of the most widely used content management systems in the world; since its release in 2005, it has been downloaded to over 50 million devices. It is free and open source, and many free extensions are available for use with it. Technically speaking, Joomla is a content management system, which means that it organizes the content on a website. The first thing a user sees when using a website, whether the website was made using Joomla or some other CMS, is the template, which determines the appearance and visual layout of a website, as well as the user experience. The term "theme" refers not only to the template, but also to everything else on the website, such as images and scripts.
Using a Responsive Joomla template can help you create the theme your website needs, whether it is a multipurpose theme or a Niche theme. It is important to have a responsive theme, because there are so many devices out there today from which people might access your website. The internet is always with us these days; it on our big screen TVs and in our pockets. Having a responsive theme means that your website will be the same when someone accesses it from a computer, a tablet, or any smart phone according to the customer's requirement. It will display properly on all of these devices and will save you the trouble of making a new theme for every device from which you want your site to be visible.
The good news about multipurpose themes is that they are easy to customize, and they do not really cost more than basic themes. They are easy to use; on some of them, you can even copy and paste design settings from one part of your site to another, and some multipurpose themes even offer unlimited sidebars. Meanwhile, a niche theme is a theme that is custom-made for you. The advantage of those is that you do not have to do the customizing yourself; it is already done to your specifications. The disadvantage is that niche themes are more expensive.
If your business needs to make lots of different themes, then a multiple purpose theme is your best bet, especially if you have the time to invest. If you just need one very professional looking site, then a niche theme is your best choice, especially if you are a bit of a technophobe.
