Bootstrap 3 - spacing issues - css

Question

I am building a simple form using Bootstrap in which I am facing some layout issues related to spacing. This is how the form looks like
There is lots of space between the label and fields. For instance, in the above image empty space between label and name field is highlighted. I would like to increase the width of input field so that the space reduces.
I would like to get rid of the vertical space between 2 fields. For instance, there is a space between author and IP fields. I would like them to be closed together. Again, not able to make out the reason.
This is the fiddle I have created to reproduce the problem.
.border {
border: 1px solid;
}
.input-field {
height: 20px
}
.custom-label {
line-height: 3.3em !important;
}
.label-size {
font-size: 10px;
line-height: 2.1em;
}

Any help is much appreciated.

Answer 1

I made some format changes to your code see if this fix your need.
http://jsfiddle.net/ayang10/sbcobqz9/66/
.form-horizontal .control-label {
text-align: right;
margin-bottom: 0;
padding-top: 7px;
}
should fix your format/alignments
