CSS Rules and Declarations
CSS (Cascading Style Sheets) is a style sheet language used for describing the look and formatting of a
document written in HTML. It is a cornerstone technology of the World Wide Web, alongside HTML and
JavaScript.
CSS Rules
1.CSS rules are made up of two parts: the selector and the declaration.
2.The selector is a pattern that identifies the HTML element that the rule applies to.
3.The declaration contains the properties and their values that will be applied to the selected
element(s).
Declaration Blocks and Properties
1.A declaration block is a list of individual declarations, each separated by a semi-colon (;).
2.Each declaration includes a property name and a value.
For example:
p{
color: red;
font-size: 14px;
}
, In this example, the selector p targets all paragraph elements. The declaration block includes two
declarations: color: red; and font-size: 14px;.
CSS Selector
There are several types of CSS selectors, including:
1.Element selectors: select elements based on their HTML tag name, e.g. p, div, span.
2.Class selectors: select elements based on their class attribute, e.g. .my-class.
3.ID selectors: select a single element based on its ID attribute, e.g. #my-id.
Creating a New Project Folder
1.When starting a new web development project, it's a good practice to create a new project folder to
keep all of your project files organized.
2.Create a new folder on your computer to serve as the project root.
3.Inside the project root, create subfolders for different types of files, e.g. css, js, images.
4.Store all of your project's HTML, CSS, and JavaScript files inside these subfolders for easy organization
and access.
CSS (Cascading Style Sheets) is a styling language that is used to control the layout and appearance of
web pages.
It is used in conjunction with HTML to add visual flair to web pages.
Here are some fundamental concepts related to CSS:
Color Contrast and Checkers: Color contrast is an important consideration when designing websites.
It ensures that the text on a web page is easily readable against its background.
Checkers is a tool that helps to check the contrast ratio between two colors.
Color Theory and HSL: Color theory is a concept that deals with the mixture of colors to create new
colors.
HSL (Hue, Saturation, Lightness) is a color model that represents colors as a combination of these three
attributes.
CSS Display: Flex and Grid: Flex and grid are two display properties in CSS that help to control the layout
of web pages. Flex is used for one-dimensional layouts, while grid is used for two-dimensional layouts.
