What are the best practices associated with using classes vs IDs?
When you’re working with CSS, there are no specific reasons forcing you to use an ID over a class. However, it is best practice to only use IDs if you want a style to apply to one element on the web page, and to use classes if you want a style to apply to multiple elements.
Which one is the correct method to use selector by class name?
class selector selects elements with a specific class attribute. To select elements with a specific class, write a period (.) character, followed by the name of the class. You can also specify that only specific HTML elements should be affected by a class.
Can ID and class name be the same?
Yes, you can use same name for both id and class because both parameters have their own significance. The only problem with having same name for class and id is code readability and maintainability.
How do you name a class and ID in HTML?
Always favor lowercase, for elements, for attributes and their values, for classes and ids. Multi-word names for classes and ids should either 1., concatenate the words in lowercase without any in-between character, or 2., separate each word with a “-” (not “_”) and maintain lowercasing throughout.
Why do we use selectors?
A selector is one of the properties of the object that we use along with the component configuration. A selector is used to identify each component uniquely into the component tree, and it also defines how the current component is represented in the HTML DOM.
Which is the best ID and class name?
Use Functional ID and Class Names Deriving names from functionality (for example nav, warning) is usually the second best option, as this is tied to the structure and helps conceptual understanding and collaboration.
What’s the best way to use IDs and classes?
Talking about use of IDs and classes solely as style sheet selectors (as opposed to scripting hooks) and assuming knowledge about when to use what (I know that most of my readers are experienced), the best things to do are, in this order: 1. Keep Use of IDs and Classes to a Minimum
Which is an example of a class name?
What I mean by that is that classes are often a more flexible and solid solution for styling, I’ll try my best to explain with an example. Take the case of marking up a telephone number. You probably have a div element with a class=”tel” or something. Inside the div is the actual number.
What’s the problem with naming things in CSS?
We just gained readability and refactored our code to avoid repetition. Naming things is never easy and the nomenclature of classes and id attributes in CSS is no exception. The problem with bad naming is that it is then difficult to find yourself in its code, so it’s important to find a particular convention to organize yourself well.
