There is a spacing problem with html layout.

html 

   


 and .tool-container if there is no width:100%;, the default is not full, why? 
 I hope I can simply build a html to paste my code into it and help me find the problem. Thank you

1. If the HTML tag is not initialized, it will bring some margin/padding, so there is a gap

. 
 *{
   margin: 0;
   padding: 0;
   }

2, position:fixed; causes DIV to break away from [document stream], and cannot be full without width:100%;.

it is recommended to add the most basic knowledge to the data: block-level elements, inline elements, inline replacement elements, line height, document stream, CSS priority, and so on.

in my example overflow: auto has completed the work of clearing the float, but not in your case. This < div class= "header-right fr" > < / div > has fallen, it is too much

.

my example
