The difference between css () and addclass ()

Maintainability:

The essence of .addClass () is to add one or more classes to an element by defining style rules for a class class. The css method is to change the style of an element through a lot of JavaScript code.

Through .addClass () we can set uniform rules for the same elements in batches, which is easy to change and can be modified and deleted uniformly. If you use the .css () method, you need to specify that each element is modified one by one, and the maintenance will be modified one by one in the future, which is more troublesome.

Flexibility:

Through .css () way, it is easy to change the properties of a style dynamically, without the need to define the rules of a class class. Generally speaking, the uncertain start layout rules are handled by .css () method in the dynamically generated HTML code structure.

Style value:

The essence of .addClass () is only the addition and deletion of the class of class, can not get the value of the property of the specified style, .addClass () can get the specified style value.

Priority of the style:

Css styles have priority, and when external styles, internal styles, and inline styles are applied to the same element at the same time, the priority is as follows

External style < internal style < inline style

The .addClass () method is done by adding the class name, so the style is defined in the external file or internal style and appended to the element when needed.

The inline style is handled through the .css () method, which is directly attached to the element's style attribute

The style attribute set by the .css method takes precedence over the .addClass method.
