问题:

I tried to make custom fonts for my application. For that, I wrote this code in my html file:

<style type="text/css" media="screen">
        @font-face {
            font-family: centurySchoolbook;
            src: url(/fonts/arial.ttf);
        }
       body {
           font-family: centurySchoolbook;
           font-size:30px;
       }
</style>

In my Html Body:

<body onload="init();">
<h>Custom Fonts</h>
    <div>This is for sample</div>

</body>

But, these styles are not applied to my html body.. Any help to solve this..??

I made it work after doing the following steps:

-Put your CSS in a file, for example my_css.css:

@font-face {
    font-family: "customfont";
    src: url("./fonts/arial.ttf") format("opentype");   
        /* Make sure you defined the correct path, which is related to
            the location of your file `my_css.css` */ 
    }
    body {
        font-family: "customfont";
        font-size:30px;
    }

-Reference your CSS file my_css.css in your HTML:

<link rel="stylesheet" href="./path_to_your_css/my_css.css" />

Pay attention to the definition of your paths!

For example, let's say you have the following directory structure:

www
- your_html.html
- css
  - my_css.css
- fonts
  - arial.ttf

Then, you would have:

@font-face {
    font-family: "customfont";
    src: url("../fonts/arial.ttf") format("opentype");   
        /* Make sure you defined the correct path, which is related to
            the location of your file `my_css.css` */ 
    }
    body {
        font-family: "customfont";
        font-size:30px;
    }

and:

<link rel="stylesheet" href="./css/my_css.css" />

Note: if you use jQuery Mobile, the solution may not work (jQuery Mobile will "interfere" with the css...).

So, you may try to impose your style by using the style attribute.

Eg:

<body>
    <h>Custom Fonts</h>
    <div style="font-family: 'customfont';">This is for sample</div>
</body>

One drawback is that it seems that the style cannot be applyied on body...

So, if you want to apply the font to the whole page, you may try something like this:

<body>

    <!-- ADD ADDITIONAL DIV WHICH WILL IMPOSE STYLE -->
    <div style="font-family: 'customfont';">

        <h>Custom Fonts</h>
        <div >This is for sample</div>

    </div>

</body>

Hope this will work for you too. Let me know about your results.

Below works like charm for custom font with jQueryMobile and Phonegap:

@font-face {
font-family: "Lato-Reg";
src: url("../resources/Fonts/Lato-Reg.ttf") format("opentype");   
    /* Make sure you defined the correct path, which is related to
        the location of your file `my_css.css` */ 
}

 body *{
margin: 0;
-webkit-touch-callout: none;                /* prevent callout to copy image, etc when tap to hold */
-webkit-text-size-adjust: none;             /* prevent webkit from resizing text to fit */
-webkit-user-select: none;                  /* prevent copy paste, to allow, change 'none' to 'text' */

font-family: "Lato-Lig" !important;
font-weight: normal !important;

 }

I also faced the same problem. I put my css file in the css folder. I put the ttf file in just the www folder and it didn't work properly, so I moved my ttf file into the css folder. Here is my code:

@font-face
{
font-family: CustomArial;
src: url('arial.ttf'); 
}

html, body, div, span, applet, object, iframe,
h1, h2, h3, h4, h5, h6, p, blockquote, pre,
a, abbr, acronym, address, big, cite, code,
del, dfn, em, img, ins, kbd, q, s, samp,
small, strike, strong, sub, sup, tt, var,
b, u, i, center,
dl, dt, dd, ol, ul, li,
fieldset, form, label, legend,
table, caption, tbody, tfoot, thead, tr, th, td,
article, aside, canvas, details, embed, 
figure, figcaption, footer, header, hgroup, 
menu, nav, output, ruby, section, summary,
time, mark, audio, video {
    font-family: CustomArial;
}

If you are using jquery mobile, you have to override the font like:

.ui-bar-a, .ui-bar-a input, .ui-bar-a select, .ui-bar-a textarea, .ui-bar-a button {
    font-family: CustomArial !important;
}

You have to override the font-family in your css for whatever jquery mobile class having font-family:Helvetica, Arial, sans-serif; to

font-family:CustomArial !important;

Now it will work. You can try like this, may be its useful for you.

here your can find the .ttf the google fonts : https://github.com/w0ng/googlefontdirectory

in your .css file

@font-face {
 font-family: 'Open Sans';
 src: url('../font/OpenSans-Regular.ttf') format('truetype');
 font-weight: 400;
}

回答5:

<style type="text/css" media="screen">
    @font-face {
        font-family: 'centurySchoolbook';
        src: url('fonts/arial.ttf');
    }
   body {
       font-family: centurySchoolbook;
       font-size:30px;
   }
</style>

with quotes on the font-family and on the url worked for me, inside the html file and on Android.

It works on physical devices, but not on emulator.

The possible issues lies in default index.css in cordova. Check if the body element has style defined for "text-transform:uppercase".

Atleast that was the issue for me, after removing this from body element in default index.css if you are using in your application, may help you as well.

For me I was using gurmukhi/punjabi fonts, and after the above line removal from index.css it just worked like charm with below css definiitions only

Example :

.demo {
   font-family: anmol
}
@font-face {
   font-family: anmol;
   src: url(../fonts/anmol.ttf);
}

I was facing a similiar issue. The problem was with the path it was taking when the font was given through an external css file. To resolve this, i declared the font URL inline in the body of index.html

<div>
      <style scoped>
        @font-face {
          font-family: Monotype Corsiva;
          src: url('fonts/Monotype_Corsiva.ttf') format('truetype');
        }
      </style>
</div>

It worked after declaring the font URL in this manner.

I just copied my ttf-fonts into the directory [app-name]/css and declared the font-families in the index.css there. See attached image: my edited index.css (Check the green marked areas in the attached picture). There i also changed the style "background-attachment:fixed;" "Helvetica, Arial, no-serif…" to "Open Sans, Open Sans Condensed, no-serif", – i also deleted the line "text-transform:uppercase". After that everything worked fine with my font "Open Sans". Of course i also included my own stylesheet with declarations of the other styles and font-families of my project.

I am also using jQuery and jQueryMobile in that project. They use the same font (Open Sans), but i added additional fonts that work as well!

Happy coding!
