I do the suggestions of your post. I get to put 2 fields in the same line but in firefox can't enter to write in a text file or can select in a dropdown. Where is the problem? I write, for example:
#li_1{
float: left;
width: 45%;
clear: both;
}
#li_2{
width: 45%;
float: left;
}
#li_3{
clear: both;
}
In IE it works OK. Thanks
