Specificity: Why my CSS is being cancelled out even though it is loaded after other CSS?

Your answer is Specificity

Specificity is a mechanism within the CSS cascade that aids conflict resolution

Basically it determines preference of CSS styles, over and above the cascading nature of stylesheets

Order of Precedence of Specificity:

Type Specificity
Inline Style Highest
Highest Number of #id selectors Wins
Highest number of class, attribute and pseudo selectors Wins
Highest Number of element selectors Wins
