To guarantee the visual integrity of your custom web fonts and provide an optimal UI experience, always set font-synthesis to 'none'. This prevents browsers from artificially synthesizing bold or italic styles when a true font variation isn't loaded, ensuring your design vision is perfectly rendered without distortion.
body {
font-family: "CustomFont", sans-serif;
font-synthesis: none; /* Crucial for web fonts to prevent faux bold/italic */
}
/* Example of allowing specific synthesis if truly needed, though generally 'none' is best */
.legacy-content {
font-synthesis: weight style; /* Allows synthesis for weight and style if original font lacks it */
}
