The feature font-synthesis-position in CSS is one of the new features that enables us to have greater control over the positioning of synthetic characters within the font. This feature can be more useful when using decorative fonts, which are often the case.
This feature allows you to specify when a character in the selected fonts isn't available, which tells the browser what type of synthetic character to substitute. Overall, this feature can be useful when you are designing user interfaces for websites with specific fonts.
In the past, even when characters weren't available in a specific font, the browser itself would substitute a synthetic character for these characters, which might have appeared inconsistent with the overall font style. However, now with the use of the font-synthesis-position feature, you can specify how these synthetic characters should appear in the text to align with your design style.
Another important feature of this property is the ability to create a more cohesive user experience in websites that extensively utilize decorative fonts. For web designers looking for a unified design across their site, this feature can be quite helpful.
The simplest use of the font-synthesis-position feature is as follows:
:root {
font-synthesis-position: normal;
}
Furthermore, line by line, here is an explanation of this code:
- :root :
Includes all the elements of the page and in this example, this style applies to all elements.
- font-synthesis-position: normal; :
This line specifies that the position of synthetic characters is assumed to be set with default behavior, and the browser will not decide what to do in different positioning scenarios.
