html - HTML5/CSS Page displays correct in Chrome but not in Firefox -

I'm trying to decide my webpage for it and if you want to travel, you will see that in Firefox Does not appear the header bar is correct but in Chrome it does not understand why I do. My research shows that if the firefox finds an error on the page then this screw is loading and displays the rest, however, I can not seem to find an error anywhere thanks for any help.

 says that  width  be defaulted to  100% , but there is no such reason in Firefox.  
  
  & lt; Svg width = "100%" & gt;   
 With firebase it determines that I look right in Firefox. Note that it has no effect as  style = "width: 100%;" According to   
 the default width is the same, so this may be a bug with Firefox
