I am using the code below, that I found on this link here and it works OK for the following controls:
SfTextBox, SfNumericTextBox and SfComboBox.
Is it possible to include the SfDropDownList and also for the SfTextBox Disabled and the SfDropDownList Disabled too ?
.e-float-input.e-control-wrapper:not(.e-error) input:valid~label.e-float-text, .e-float-input.e-control-wrapper:not(.e-error) input~label.e-label-top.e-float-text{
font-style:italic;
font-size: 11px;
font-weight: bold;
}
