Basics of CSS

Cascading Style Sheets (CSS) is a fundamental technology for designing and styling web pages. It provides the means to control the layout, typography, color, and other visual aspects of HTML documents. If you’re new to web development or looking to expand your skills, mastering CSS is essential.

Selectors and its types in CSS

CSS selectors are used to target HTML elements and apply styles to them. Here are some common types of selectors:

• Element Selector: Targets elements based on their tag name.

element {
    property: value;
}

• Class Selector: Targets elements with a specific class attribute.

.classname {
    property: value;
}

• ID Selector: Targets a single element with a specific ID attribute.

#idname {
    property: value;
}

• Descendant Selector: Targets elements that are descendants of a specified element.

parent descendant {
    property: value;
}

• Child Selector: Targets elements that are direct children of a specified element.

parent > child {
    property: value;
}

• Attribute Selector: Targets elements based on their attributes.

element[attribute="value"] {
    property: value;
}

• Pseudo-class Selector: Targets elements based on their state or position.

selector:pseudo-class {
    property: value;
}

• Pseudo-element Selector: Targets specific parts of an element.

selector::pseudo-element {
    property: value;
}

• Universal Selector: Targets all elements in a document.

* {
    property: value;
}

CSS Box Model:

The CSS Box Model describes the layout of elements on a web page. It consists of four main components: content, padding, border, and margin.

• Content: The actual content of the element, such as text or images.
• Padding: Space between the content and the element’s border.
• Border: A border surrounding the padding.
• Margin: Space between the border and adjacent elements.

Media Query:

Media queries allow developers to apply different styles based on the characteristics of the device, such as screen size, resolution, or orientation. This enables the creation of responsive web designs that adapt to various devices and screen sizes.

Animation and Transition:

CSS animations and transitions allow developers to create visually appealing effects, such as moving elements, fading in/out, and changing colors. Animations are more complex and allow for greater control over timing and keyframes, while transitions provide simple effects for property changes.
