stylesheet only screen

[Kelly]

Questo codice funziona con Explorer 11, mozilla, Google Chrome, browser iphone, android, safari...
ma non funziona con Explorer 8 /9/10...
sapete per caso la causa?

ogni file carica delle dimensione precise secondo il tipo di schermo....
quando apro Explorer 8 dal pc .... è come se non lo leggesse...

port.css (telefonici android-iphone)
tablet.css (ipad)
pc.css (pc)

grazie

Non lo so se intendi questo, ma potresti usare "conditional comments". Prova a cercare su internet se è questo. La stessa cosa la puoi fare nel css. Eccoti un esempiO:

<p class="accent">
<!--[if IE]>
According to the conditional comment this is IE<br />
<![endif]-->
<!--[if IE 6]>
According to the conditional comment this is IE 6<br />
<![endif]-->
<!--[if IE 7]>
According to the conditional comment this is IE 7<br />
<![endif]-->
<!--[if IE 8]>
According to the conditional comment this is IE 8<br />
<![endif]-->
<!--[if IE 9]>
According to the conditional comment this is IE 9<br />
<![endif]-->
<!--[if gte IE 8]>
According to the conditional comment this is IE 8 or higher<br />
<![endif]-->
<!--[if lt IE 9]>
According to the conditional comment this is IE lower than 9<br />
<![endif]-->
<!--[if lte IE 7]>
According to the conditional comment this is IE lower or equal to 7<br />
<![endif]-->
<!--[if gt IE 6]>
According to the conditional comment this is IE greater than 6<br />
<![endif]-->
<!--[if !IE]> -->
According to the conditional comment this is not IE 5-9<br />
<!-- <![endif]-->
