How to change spacing between radio button and its text?

Many HTML elements have a default margin setting. You can override this and set it to 0. In your case, you want to reset margin-right on the radio button:

<input type="radio" name="beds" value="1" style="margin-right: 0" />1+

You probably want to add it to your stylesheet so that it applies to all radio buttons:

input[type="radio"] {
  margin-right: 0;
}

Just change the input id's width to auto in css.

#input-id {
width: auto;
}

You'll need the label element.

<input type="radio" name="beds" value="1" id="first" /><label for="first">1+</label>
<input type="radio" name="beds" value="2" id="second" /><label for="second">2+</label>

You can then style this like this:

label {
  margin-left: -3px;
}

Also note the use of the for attribute for accessibility purposes.
