CSS, short for Cascading Style Sheets, is a fundamental technology used in web development to control the presentation and layout of HTML documents. It serves as a styling language that defines how HTML elements should be displayed on a web page.
CSS provides a set of rules and properties that allow developers to specify various visual aspects of web pages, such as colors, fonts, spacing, positioning, and more. By separating the content (HTML) from its presentation (CSS), developers can create consistent and visually appealing designs across multiple pages of a website.
CSS selectors are patterns used to select and style HTML elements based on their attributes, relationships with other elements, or specific characteristics. Selectors target elements in the HTML document and apply styles to them, allowing developers to control the presentation and layout of web pages. Here are some commonly used CSS selectors:
Element Selector: Selects HTML elements by their tag name. For example, p selects all
elements.
Class Selector: Selects elements with a specific class attribute. It begins with a period (.) followed by the class name. For example, .btn selects all elements with the class "btn".
ID Selector: Selects a single element with a specific ID attribute. It begins with a hash (#) followed by the ID name. For example, #header selects the element with the ID "header".
Universal Selector: Selects all elements in the document. It uses an asterisk (*). For example, * selects all elements.
Attribute Selector: Selects elements based on their attributes. It can target elements with specific attribute values or attributes of specific types. For example, [type="text"] selects all elements with the attribute type="text".
Descendant Selector: Selects elements that are descendants of another element. It uses whitespace to indicate the relationship. For example, div p selects all
elements that are descendants of
elements.
Child Selector: Selects elements that are direct children of another element. It uses the greater than sign (>). For example, ul > li selects all elements that are direct children of
- elements.
Adjacent Sibling Selector: Selects elements that are immediately preceded by a specified sibling element. It uses the plus sign (+). For example, h2 + p selects all
elements that are immediately preceded by an
element.
Pseudo-classes: Selects elements based on their state or position in the document. Pseudo-classes begin with a colon (:). For example, :hover selects elements when they are hovered over by the mouse.
CSS comments are used to add notes or explanations within the CSS code. Comments are not displayed in the web browser and are solely intended for developers to understand the code better. There are two types of CSS comments:
Single-line Comments: Single-line comments start with /* and end with */. They can only span one line of code.
/* This is a single-line comment */
Multi-line Comments: Multi-line comments also start with /* and end with */, but they can span multiple lines of code.
/*
This is a multi-line comment
It can span across multiple lines
*/
CSS Borders:
CSS borders are used to create visible boundaries around HTML elements. Borders can be customized in terms of style, color, and width. The border property is used to set all border properties in one declaration, or individual border properties like border-width, border-style, and border-color can be set separately.
Example of using individual border properties :-
/* Set different border properties individually */
border-width: 2px;
border-style: solid;
border-color: red;
In CSS,
elements.
Example of a
element in HTML :-
This is a div element.
CSS Margin:
CSS margin is the space around an element's border. It creates space between the element's border and adjacent elements. Margin can be set using various CSS properties such as margin-top, margin-right, margin-bottom, and margin-left. You can specify margin values in different units such as pixels, percentages, ems, or using keywords like auto.
Example of setting margin using shorthand property :-
/* Set different margin values for each side */
margin-top: 10px;
margin-right: 20px;
margin-bottom: 30px;
margin-left: 40px;
CSS Padding:
CSS padding is the space between an element's content and its border. It creates space inside the element. Padding can be set using properties such as padding-top, padding-right, padding-bottom, and padding-left. Like margin, you can specify padding values in pixels, percentages, ems, or using keywords like auto.
Example of setting padding using shorthand property :-
/* Set different padding values for each side */
padding-top: 10px;
padding-right: 20px;
padding-bottom: 30px;
padding-left: 40px;

CSS Hover Effects on Iframe Tag:
Hover effects on tags can be a bit limited compared to other elements because elements typically display external content like web pages or videos, and CSS may not directly manipulate the content inside the . However, you can still apply hover effects to the itself, such as changing its border or background color.
Here's an example of applying a hover effect to an element :-

CSS combinators are used to define relationships between HTML elements when applying styles. There are four types of combinators in CSS:
Descendant Selector (Whitespace): Selects all elements that are descendants of a specified element.
Example: div p selects all
elements that are descendants of
elements.
Child Selector (>): Selects all elements that are direct children of a specified element.
Example: div > p selects all
elements that are direct children of
elements.
Adjacent Sibling Selector (+): Selects an element that is immediately preceded by a specified element.
Example: h2 + p selects the
element that is immediately preceded by an
element.
General Sibling Selector (~): Selects all elements that are siblings of a specified element.
Example: h2 ~ p selects all
elements that are siblings of
elements.CSS Specificity :-
It is the set of rules that determines which CSS styles are applied to an HTML element when multiple conflicting styles are defined. It's important to understand specificity to ensure that styles are applied as intended.
CSS math functions allow you to perform mathematical operations directly within your CSS code. These functions can be useful for dynamically calculating values such as lengths, sizes, or colors based on other CSS properties.
