What is the precedence of each method of CSS inclusion?

When multiple CSS rules apply to the same element, the browser uses a system of precedence to determine which rule takes effect. This precedence is based on the location and specificity of the styles. More specific or closer styles override more general or distant ones.

Note that specificity (e.g., ID selectors vs. class selectors) and source order (last defined wins when specificity is equal) also influence which styles apply. However, inline styles and !important declarations usually dominate.
