Hello there asking for your help I published my site www.giovannicaroccia.it/ although it is not definitive, but I have problems viewing the home page with different browsers, with explorer is displayed correctly, while crome and mozilla display is not correct you can give me some help on what to change to get a correct display on all browsers.
thanks

It's fine on all my browsers. you should change the image in slideshow with a dard color image so you can see the menu. OR you need to change color of menu so it has a good visible

sorry
but I still need your help I tried to change the image size of the home page but I did not get results, I am attaching a picture to show the difference in view between 6 and explorer google crome
the left image is obtained with the correct explorer 6, while the right is quaver and appears much larger.
thanks

first, IE 6 is out of date and we dont support it.
Chrome is working fine. It works as the our demo. the issue is that you use a white image as a background image so it make you think there is a problem. as i mentioned in prev post. you should use other image (dark image) or change the color of the menu.

OR you can try to remove follow code in templates/jf_calla-exteriors/css/template.css

Hello, I made ​​the change that you suggested but I did not get results, but this line always changing css: background-size: cover; in place of the cover with 100%
/ * SLIDESHOW * /
# {jf-slideshow
     background-clip: border-box;
     background-color: # 73050th;
     background-image: url (.. / images / banner.jpg);
     background-origin: padding-box;
     background-position: center center;
     background-repeat: no-repeat;
     background-size: cover;
background-attachment: fixed;
     position: relative;
     z-index: 50;
I got unmodesto result that the home page is now displayed in the correct way,
However, sliding the page the color of the menu I still black what should I change to get the same color as the other pages. Thank you

You should remove below css code from templates/jf_calla-exteriors/css/template.css
home #jf-header.transparent {
background: none repeat scroll 0 0 rgba(0, 0, 0, 0.;
}
