This is a basic plugin for jQuery which adds an effect for slowly fading in text. There may be other plugins out there that have similar functionality, but this was an attempt to try building such a thing. Demo The Code

I’ve seen this somewhere before… HTML <span id=”smScreenIndicator”></span> CSS #smScreenIndicator { float: left; } @media (min-width: 400px) { /* whatever width suits the project */ #smScreenIndicator { float: none; } } JQuery function isMobile() { if ( $(‘#smScreenIndicator’).css(‘float’) == ‘left’ ) return true; else return false; }
