Have you ever looked your company's website on a smartphone?


Are all contents visible?

A content created with Flash cannot be correctly visible on a tablet or a mobile phone. Now, it has become possible to create contents almost as identical as Flash contents by combining the HTML/ CSS3 or jQuery (javascript) technologies. Besides, it is said that Flash does not enable to do a SEO strategy (Search Engine Optimization).

The Web technology is constantly in evolution. The technologies and designs of yesterday can be rapidly outdated.

Is the layout well adapted to smartphones?

Today, it became normal, almost mandatory to create a website that can adapt itself to all types of devices to tablets, smartphones or computers. The new trend is “the responsive layout”, a new technology which enables the website to change and adapt the design and size of the letters according to the browser of the screen used. There is no need of having a different website according to the device used and IT support has become much easier.
