Other user can read helvetica neue in browser without install the font? - css

Question

I have to use 'helvetica neue' as my asp.net default font. After installed in my pc, I able to add the font into my css, and it is worked while run the web application at local. But after I deployed into server. The 'helvetica neue' font is not working. Is it have to install the font on user computer?
My CSS:
#font-face { font-family: Delicious; src: url('../css/Fonts/HelveticaNeueLTPro-CnO.otf'); }
body
{
background: #fff;
color: #333;
/*font-family: HelveticaNeueLT Pro 63 MdEx;*/
font-family: Delicious, sans-serif;
font-size: 76%; /* all font sizes are related to this initial 'small' font-size setting (which is more or less 12pt) */
min-width: 730px; /* min- and max-width don't work in IE Win 6 and below */
max-width: 1250px;
}

Answer 1

your #font-face is not complete, and you need some more files:
EOT for IE,
SVG fir Ipad,
WOFF for FireFox
TTF/OTF for the rest
You can create those font files at Font Squirrel
#font-face {
font-family: 'Delicious';
src: url('../css/Fonts/HelveticaNeueLTPro-CnO.eot');
}
#font-face {
font-family: 'Delicious';
src: url(//:) format('no404'),
url('../css/Fonts/HelveticaNeueLTPro-CnO.woff') format('woff'),
url('../css/Fonts/HelveticaNeueLTPro-CnO.ttf') format('truetype'),
url('../css/Fonts/HelveticaNeueLTPro-CnO.svg#Delicious') format('svg');
font-weight: normal;
font-style: normal;
}
