And is that with the querySelector we can get elements from the HTML that we don't give an class or an id by it's type, so I don't named the div, but how I have only one div in the HTML the querySelector will get it, and it don't have id or class I said what is.
And other I have class and id, of course in the end they do the same, in other words if you use id in the place of class and the contrary would work; but for instance the class you can pretend have 20 elements that will be changed in CSS or fetch in JS of the same way and id is like personal like an id of a human, and is for the changes that affects only the lonely element that have that id, but works you give the same id for more than one element so isn't mandatory, and this way id was used like a class, the elements doesn't even need be of the same type all 'p' or all 'div'.
Other when I study law I learn that have remissive index that is in the end of the book that went there and could find in an list in alphabetical order the defininations you have in the book, this is very need when you are studying because you can didn't understand an definition that if you don't have you don't gonna evolute in the study because the understand only gonna happens if yuo knew previously of something that is named in text, and in the Mozilla is like the same there is a reference, sometimes you know HTML, CSS, JS but don't remember all so you use it like an manual, sometimes the more efficient is who know look for because will receive an answer, I am saying that sometimes is good a person that know to find the answer for one question, also make easy the person learn with all the definition, the technical name, because yuo gonna have a faster answer cos you gonna ask for the exactly name, the problem of the remissive index is you think that will replace the study and will not , the remissive index is just more one way for the best student evolute more and more fast then the others.
