The fundamental structure of jQuery for selecting elements and performing actions: $(selector).action()

They are used to find or select specific HTML elements on a web page based on criteria like their ID, class, or type, enabling you to apply actions to them.

They use a syntax based on CSS selectors, but with added features from jQuery. It's a flexible way to identify elements using a variety of criteria.

It's the symbol used to designate and access the jQuery library. It's essential for using any jQuery functionality.

This part represents the selection of specific HTML elements based on the criteria specified within the 'selector'.

This component defines the action you want to perform on the selected HTML elements. It can be hiding, showing, modifying, or any other function supported by jQuery.

The * selector in jQuery selects every single HTML element on the page. It's a wildcard that matches everything.

The $(this) selector refers to the current HTML element that triggered an event, like a click. It's very useful for handling individual element events.

You use a period (.) followed by the class name. For example, $('.intro') selects all elements with the class 'intro'.

You use square brackets ([]) with the attribute name and optional value. For example, $('a[target='_blank']') selects all anchor elements with the 'target' attribute set to '_blank'.

These selectors select every other row. :even selects even rows, while :odd selects odd rows. This is great for visual effects like alternating row colors.

You can use .hide() method after selecting the desired element. For example, $('#p1').hide() will hide the element with the ID 'p1'.

This line of code ensures that your jQuery script will only run after the entire HTML document has finished loading. It's important to avoid errors caused by scripts trying to work with elements that aren't fully loaded yet.

Targets the first element in a group of elements, regardless of their type. It's useful for working with the initial element in a set.

The mouseenter event is triggered when a user moves the mouse pointer over an HTML element.

The mouseleave event is triggered when a user moves the mouse pointer out of an HTML element.

The mousedown event is triggered when a user presses a mouse button down while the pointer is over an HTML element.

The mouseup event is triggered when a user releases a mouse button that was previously pressed down while the pointer is over an HTML element.

The hover event is triggered when the mouse pointer moves over an HTML element and then away from it, creating a hover effect.

The .click() function in jQuery is used to attach an event handler to an HTML element that will be executed whenever the element is clicked by the user.
