When the float:right property is applied, the text to the right of the checkbox appears in two lines. If the float:right property is not used, one line comes next to the checkbox and the rest starts below it.
Below you can find the code snippet including the float property:
input[type=checkbox] {
margin-top: 10px;
margin-right: 10px;
}
label {
width: auto;
float: right;
}
<input type="checkbox" name="optIn" value="Y">
<label for="ext-comp-1035">I would like to receive email from you. By checking the box you agree that you have read the Privacy Policy and Terms of Use</label><br>
