Arrange inputs into euqal length : I have multiple rows with inputs

    <input type="text" style="width: 50px;" > 
    <br/>
    <input type="text" style="width: 25px;" > 
    <input type="text" style="width: 25px;" > 

Unfortunately the `25+25 != 50` because there is a space between, which varies by each browser.

Question: How to style the inputs to get `2x25` has equal lenth with `1x50`
