I would like it to be displayed like this as link2

I have 4 requested changes below.
1) Change the font-size and font-family of the text "check availability at".
2) Ensure the gap between text, textfield, and button is consistent.
3) When entering numbers in the textfield, add a bit of space at the beginning as shown in link 2.
4) Hide the empty gap between the block above and below.
