Experienced developers will share that when they began, they spent many hours trying to figure out why a style change didn’t “take”.
If we do not understand the precedence order of CSS, we will be confused by the presentation of our styled HTML elements.
On a single web page we could have multiple styles:
multiple external stylesheets
internal stylesheet
inline stylesIf these sources of CSS accidentally or intentionally style the same element differently, we get into “cascade order” rules.
This is a link to a description of Cascade Order: https://www.w3schools.com/css/css_howto.aspScroll down to the bottom to view “Cascading Order”In general, the styling closest to the element “trumps” preceding styles.And if there are multiple external stylesheets, the last one listed has precedence.
