What is a Css Mobile Detection Overlay?

Responsive css code is used on some template models to allow the webpages to display an overlay link box selection. The code detects the browser width using css media queries. If the width of the browser is less than the "threshold" (or breakpoint) you set (320, 480 or 640 pixels), the hidden div pops up in the center of the page. If the width is a standard PC or Mac browser, the div will be hidden unless the browser width is below the set threshold. The overlay box links to an integrated mobile sub-site.


Web Templates That Include a Detection Overlay

The following web templates also include a mobile version sub-site

Features:

  • Compliant in all css3 web browsers and smartphones.
  • Editable width threshold (768, 640, 480, 320, etc). Set the box to popup at the desired width in the global css file.
  • Editable link text, replaceable icon images.
  • Editable colors using standard css code.
  • Works on any website.
  • Fully SEO compliant (See section below.)
  • Can be added to some or all webpages on the site.
  • Available in select Allwebco templates or as a website add-on.

Viewing the Overlay in Action

To view a working overlay and see the dynamic response, go to our color theme drop menu templates, click any thumbnail to view a sample website. With the site open on the homepage make your browser width narrow and the overlay will popup on the page. Make your browser width wider and the overlay disappears using css code. A CSS3 compliant browser is required (IE9+, Google Chrome, Safari, Firefox, Opera).


SEO Benefits

Because the overlay uses only css, with no Javascript or jQuery for the detection, your website will rank normally in search engines like Google and Bing. The css simply hides the overlay until the browser width is narrow enough to be a mobile device. A Javascript is included to allow the overlay to close, or hide, when the user clicks either the close button or away from the link box.


Custom Smartphone & Tablet Setting

You can set the overlay "threshold" from 320 to 480 for mobile only, 768 for mobile and some tablets, or we use a default of 652 in the templates so it will not display on tablets but will display on all small screens. Optionally you can set the threshold or "breakpoint" width to any number you prefer.
