localeTitle: Изменение CSS элемента с помощью jQuery
---
## Description
2019-08-28 16:26:13 +03:00
< section id = 'description' >
Мы также можем изменить CSS элемента HTML непосредственно с помощью jQuery. Функция jQuery имеет функцию под названием < code > .css()</ code > которая позволяет вам изменять CSS элемента. Вот как мы изменим е г о цвет на синий: < code > $(" #target1 " ).css(" color" , " blue" );</ code > Это немного отличается от обычного объявления CSS, поскольку свойство CSS и е г о значение находятся в кавычках и разделены запятой, а не двоеточием. Удалите селектор jQuery, оставив свободную < code > document ready function</ code > . Выберите < code > target1</ code > и измените цвет на красный.

- text: Only use jQuery to add these classes to the element.
