How is the order of precedence for CSS styles determined?

The order of precedence for CSS styles is determined by the specificity of the selectors and the order in which they appear. This means that more specific selectors will take precedence over less specific ones, regardless of the order in which they are defined.

For example, a style applied to a class selector (e.g., .classname) will generally have higher specificity than a style applied to a tag selector (e.g., div), even if the tag selector is defined after the class selector in the CSS file. Furthermore, if two selectors have the same specificity, the one that is declared last in the CSS file will take precedence. This system allows for a structured hierarchy in applying styles, where you can create rules that target elements more specifically as needed.

The other choices don't correctly describe how CSS specificity and precedence work. The size of the CSS file does not affect precedence; some browsers may interpret styles differently, but this is not the rule for determining specificity; and the content type of the webpage has no bearing on how CSS styles are prioritized.
