I used this code for 2 text boxes and it worked:
Qualtrics.SurveyEngine.addOnload(function() {
jQuery("#"+this.questionId+" .TextEntryBox").each(function() {
var tb = jQuery(this);
tb.css({"float":"none","background-color":"white","width":"100%"});
tb.prev("label").css("display","block").append(" ").append(tb);
});
});
