In CSS, specificity refers back to the weight or priority of a selector. It determines which type rule will likely be utilized to a component when a number of guidelines are relevant. The “first descendant” precept performs an important position in specificity by permitting builders to focus on components based mostly on their place within the DOM tree. Through the use of the “>” selector, builders can choose components which can be the primary baby of a selected father or mother component. This method will increase the specificity of the selector, guaranteeing that types are utilized solely to the meant components.
Think about the next instance:
“`css/ Rule 1 /.container { shade: pink;}/ Rule 2 /.container > p { shade: blue;}“`
On this instance, Rule 1 units the colour of all components with the category “container” to pink. Rule 2 units the colour of the primary paragraph component that could be a baby of a component with the category “container” to blue. As a result of Rule 2 has a better specificity on account of using the “>” selector, it would override Rule 1 and the primary paragraph component will likely be coloured blue.
