[mysta11]

Hi Team,

Can you help to show how can i do some thing with my web site:

1) If i had chose VN langue, my website showed wrong some where, see picture below:

So, i want to change font which display which VN or other language.

2) I'd to add a image behind the UPLOAD button? I found a topic which i not sure that can it resolve my request because i didn't know i must add code to what file.

3) How can i add a comment field when view a picture? I found a comment option in my website "Comment Code", i accessed to FB (https://developers.facebook.com/docs/plugins/comments) got a comment code, i put it to this field but the same result -> Comment field didn't show, my code:

<div class="fb-comments" data-href="http://gauxinh.net" data-numposts="5" data-colorscheme="light"></div>

That is because the system uses the OpenSans font. To override this font go to Dashboard > Settings > Theme > Custom CSS and paste something like this:

html, body {
    font-family: Helvetica, Arial, sans-serif;
}

You can use any font there in the font-family line. The first one on the left is the 1st priority.

For the background add this CSS:

#home-cover {
    background-image: url(http://demo.chevereto.com/images/2014/09/03/tumblr_mbmp4hWL451qz4mo8o2_1280.jpg);
    background-size: cover;
    background-position: 50%;
}
