After reviewing the link you shared, I have outlined the steps to achieve your goal.
To begin, visit fontsquirrel and upload the file named BALLW___.TTF. The website will then generate the necessary font extensions along with the fontface rules. An example of the font-face rules would be:
@font-face {
font-family: 'fontname';
src: url('fontname-webfont.eot');
src: url('fontname-webfont.eot?#iefix') format('embedded-opentype'),
url('fontname-webfont.woff') format('woff'),
url('fontname-webfont.ttf') format('truetype'),
url('fontname-webfont.svg#fontname') format('svg');
font-weight: normal;
font-style: normal;
}
Insert this code into your CSS file and then you can utilize it as follows:
css selector
{
font-family: 'fontname';
}
Note: Remember to also upload your fonts before implementing these changes.
