سلام

ببخشيد تو مجيد آنلاين گشتم ولي نتونستم اين كد را درست كنم

من از توضيحات شرطي در سي اس اس استفاده كردم ولي جواب نداد

مي خواستم متخصصين درستش كنن

من ميخواهم كه در مرور گر opera تمام ورژن ها اين اندازه را تغيير دهم.

کد: 
margin-right: 150px;

در اين كد

کد: 
#ls
{
font-family: tahoma;
background-color: #efeded;
font-size: 12px;
width:120px;
margin-right: 150px;
margin-top: -10px;
border: 0px;
padding-right: 5px;
}

اينم تمام كد

کد:

درود بر شما
شما می تونید مقدار های مورد نظر خود را برای مرورگر OPERA در یک فایل CSS جداگانه قرار دهید، سپس توسط جاوا اسکریپت به آن اختصاص دهید:

شما حتی می توانید در مثال بالا، برای هر مرورگر، یک فایل CSS جداگانه در نظر بگیرید.
حتی می توانید نسخه مرورگر را هم مشخص کنید.
