Overflowing text
When form fields are too small, placeholder text can get cropped in an undesirable way. You can use the text-overflow property to alter the way overflowing text is displayed.
HTML
<input id="input1" placeholder="Name, Rank, and Serial Number" /> <br /><br />
<input id="input2" placeholder="Name, Rank, and Serial Number" />
CSS
#input2:placeholder-shown {
text-overflow: ellipsis;
}
