海外TECH	DEV Community	A Complete Guide to How the CSS not Selector Works	https://dev.to/smpnjn/a-complete-guide-to-how-the-css-not-selector-works-5djo	A Complete Guide to How the CSS not Selector WorksIn CSS it s often necessary to sign post that we want to select an element but not in specific circumstances like if it has a certain class In these instances we can use the not selector to do that Let s look at how it works CSS not SelectorThe CSS not selector is broadly supported by most browsers The way it works is that we create a selector and then specify what it should not be For example say you have the following HTML lt div class not red gt Not Red lt div gt lt div class not red gt Not Red lt div gt lt div gt Red lt div gt lt div gt Red lt div gt We have a bunch of divs here and some shouldn t be red If we want all divs in general on our page to be red except for not red elements we can use not not red to ensure they remain well not red div not not red color red Here s another example By default all elements will have the Arial font except for old fashioned elements lt div class old fashioned gt Old Fashioned Text lt div gt lt div gt Some Text lt div gt Our CSS where only non old fashioned elements use the Arial font looks like this div not old fashioned font family Arial sans serif CSS not Selectors Increase SpecificityYou might be familiar with the concept of specificity in CSS where certain selectors override others For example a class has a lower specificity than an id so any id CSS properties will override class properties on the same element The not selector also affects specificity For example if you had div not id in your code it still counts as having an id so the specificity increases as if it has an id This is useful to remember when using not CSS not Selectors and the DOM structureOne confusing thing about not is when you try to use it to stop styles applying to things within elements For example suppose you have the following HTML lt div class container gt lt form gt lt div class input element gt lt input type text gt lt div gt lt form gt lt div class input element gt lt input type text gt lt div gt lt div gt Let s say you want to apply a style to only input elements which are not within form elements Simple right You might try something like this div not form input border px solid red Only this won t work and the reason why is that not is applied at every level and we are wrapping each input in input element That means that not form is applied to input element and it is indeed not a form So both input elements will have a red border To avoid that you need to remove the wrapper element and have the input be a direct child of the form lt div class container gt lt form gt lt input type text gt lt form gt lt input type text gt lt div gt That way the input in the form will not inherit the styles from div not form input CSS not Selector SupportIt is important to note that there are two versions of the not selector one which accepts only a single simple CSS selector and the newer update to not which accepts any CSS selector All browsers support single simple not selectors like the ones we ve used so far including Internet Explorer However not all browsers support complex selectors With simple selectors in not you can do all of the following not id not class not element not attrbute However things like the following are only available with complex selectors not id class attribute not id class not element id id class Fortunately support for complex selectors is still quite high The only browser not supporting complex selectors today is Internet Explorer and some mobile browsers	2022-08-06 15:22:15
