One of the hardest parts of building Responsive WordPress themes is maintaining responsive integrity after the site goes live. User Admins can have limited coding abilities which can prevent them from maintaining responsiveness in themes.
WP Mobile Detect aims to make it extremely easy for anyone to wrap content in the editor with shortcodes which will hide content based on visitor device at the server level.
No longer do we need to rely on display:none; or other techniques to hide content for mobile devices. Instead we can replace content with alternatives. When a full-size infographic in your post is unknowingly displayed on a visitors phone we can consider that an Non-user initiated download. In other words that visitor had no idea what they were getting into and you possibly just choked their bandwidth.
WP Mobile detect gives you the ability to wrap that infographic in a [notdevice][/notdevice] shortcode so at the server level WordPress will decide to show that content only if the user is NOT on a phone or tablet. Alternatively you can wrap a link and corresponding text to that info graphic in a [device][/device] shortcode as a way for the visitor to consume that content if they so choose.

So, you’re tired of people visiting your modern website with an outdated browser and not doing anything about it. Maybe they aren’t “power” users, maybe it’s your auntie running a last century browser trying to see awesome CSS3 animations and transforms. Let the user know that’s an outdated browser, and advise them on a better one.
With this solution you can check if the user’s browser can handle your website. If not, it will show a cool looking notice advising the user to update the browser. It’ll be up to him/her to decide if he upgrades or not. Don’t force the user!
That’s it! As simple as it can get.
