Diving into Basic CSS Syntax

Welcome to our journey into the world of CSS! CSS (Cascading Style Sheets) is the language that transforms the appearance and layout of your HTML documents, bringing them to life.

What is CSS?

CSS stands for Cascading Style Sheets. It's a styling language that allows you to control the appearance of HTML elements on a web page. You can use CSS to change the font, color, size, layout, and more.

CSS Syntax: The Anatomy of a CSS Rule

A CSS rule consists of a selector that identifies the HTML element(s) to be styled, followed by a declaration that defines the styling. The declaration contains one or more property-value pairs.

Comments in CSS

Comments in CSS are used to provide information or notes about your code. They start with /* and end with */, and are ignored by the browser.

CSS Selectors: Types of Selectors

CSS selectors are used to select HTML elements based on their attributes, class, ID, or other criteria. There are various types of selectors, including universal, type, class, ID, and attribute selectors.

CSS Selectors: Universal, Type, and Class Selectors

  • Universal selector - * - selects all elements in a document
  • Type selector - h1, p - selects elements based on their HTML tag name
  • Class selector - .my-class - selects elements with a specific class attribute

CSS Selectors: ID and Attribute Selectors

  • ID selector - #header - selects an element with a specific ID attribute
  • Attribute selector - [type="submit"] - selects elements based on the value of a specific attribute

CSS Selectors: The Power of Combinations and Negations

You can combine multiple selectors using combinators (e.g., space, >, +, ~) to select elements based on their relationship to other elements. Negation (:not()) allows you to exclude elements from a selection.

CSS Properties: Types and Value Formats

CSS properties are used to specify the styling of elements. There are various categories of properties, such as text properties, background properties, border properties, and more. Each property has a specific value format that defines how the property is applied.

CSS Properties: Styling Text

CSS provides extensive options for styling text. You can control properties like font-family, font-size, color, text-align, and more. Experiment with different properties to create visually appealing and meaningful text.

CSS Properties: Styling Backgrounds

CSS allows you to customize the background of elements. You can set the background color, add images, specify the repeat pattern, and even use gradients and other effects to create unique and eye-catching backgrounds.

CSS Properties: Styling Borders

Borders provide visual definition to elements. With CSS, you can control the width, style, and color of borders. Create boxes, separate sections, or add subtle embellishments to your designs using border properties.

CSS Properties: Styling Dimensions

CSS provides properties for controlling the dimensions of elements. Set the width, height, padding, and margins to create the desired layout and spacing. These properties enable precise control over the size and position of your elements.

CSS Properties: Styling Lists and Tables

Lists and tables are essential elements for organizing and presenting data. CSS offers specific properties for styling both lists and tables. Customize the appearance of list items, bullets, table headers, and rows to enhance the readability and visual appeal of your content.

CSS Properties: Positioning Elements

CSS provides powerful options for positioning elements on a web page. Using properties like position, top, right, and z-index, you can control the placement, layering, and visibility of elements to create complex and engaging layouts.
