Change size of a Date Picker

I'm trying to change the width of a date picker. I've added what I think is the required CSS, and the form look correct in design view, but when I preview the form, it looks different and incorrect

The code I've added is

#label_21 {

 width: 700px !important;

}

#lite_mode_21 {

 width: 75px !important;

}

Hello,

After some testing, it doesn't seem like the field wants to change size without changing the parent tag. In this case it's #cid_21.

The form it self is about 700 pixels wide, so with the width of the label set to 700px, it pushes the field down.

#label_21 {

  width: 460px !important;

}

#cid_21 {

  width: 170px !important;

}

This is how it looks when I test it in my own form:

Is this what you were looking for, or is there something else that should be changed still?

Best regards,
Lars
