How to auto-update information on the client?

Question

css

We have code:

<?php

header("Refresh: 1;");
echo mt_rand(10, 15);

?>

How can I make sure that only the information is updated, but the entire page is not updated?

Answer 1

1) The font is not optimized for the web
2) One font format is not enough, you need at least 4 (ttf, eot, svg, woff)
3) Your browser may just use one of the missing formats, not ttf
Try to find your font in the format otf (it is more reliable for this operation) and convert it to the web version here , if you do not find it, then try to convert your ttf
