Please tell me about the incompatibility between firefox and chrome css_html/css_WEB-ITnose

A css novice comes to ask questions.
On chrome and ff, the code is as follows:
                                                                                                                

                                                                         ​Height: 300px;
white-space: pre-wrap; /* css-3 */
white-space: -moz-pre-wrap; /* Mozilla, since 1999 */
white-space: -o-pre- wrap; /* Opera 7 */
word-wrap: break-word; /* Internet Explorer 5.5 */
}


#editorbox2_inputword{
height: 290px;
width: 250px;
padding: 0;
outline: 0;
margin: 2px;
}

Then take a look at the effect of the picture:
chrome is normal, Why is the display of ff like that?

in css Try adding the following css at the top
*{padding:0; margin:0;}

Is there a ul tag outside the li tag?

Is there an ul tag outside the li tag?
