What is Cascading Style Sheets (CSS)?

Cascading Style Sheets (CSS) is a stylesheet language used to describe the presentation of a document written in HTML or XML (including XML dialects such as SVG, MathML, or XHTML). CSS defines how elements should be displayed on screen, on paper, in speech, or on other media. It is one of the most important technologies of the World Wide Web, alongside HTML and JavaScript.

CSS was designed to enable the separation of presentation and content, including layout, colors, and fonts. This separation can improve content accessibility, provide more flexibility and control in the specification of presentation characteristics, enable multiple web pages to share formatting by specifying the relevant CSS in a separate .css file, and reduce complexity and repetition in the structural content.

CSS Properties

CSS styles are applied to HTML elements through selectors (which target HTML tags, classes, IDs, or attributes) and declarations (which specify the properties to be altered and their new values). These styles can be included in an HTML document internally using the <style> tag, linked externally via a separate stylesheet file referenced in the <link> tag, or applied directly to specific elements with the style attribute for inline styling.

The term “cascading” refers to the way CSS applies styles to HTML elements based on a hierarchy of importance. This hierarchy determines which styles are applied when there is more than one rule for an element. The cascade follows a simple set of priorities to resolve conflicts:

  1. Importance: Styles marked !important have the highest priority.
  2. Specificity: More specific selectors override more general ones. For example, an ID selector has a higher specificity than a class selector.
  3. Source Order: When two selectors have the same specificity, the last one defined in the CSS is applied.

This cascading mechanism allows for flexible styling strategies where global styles can be set as a baseline, and specific styles can override them as needed, ensuring a consistent yet customizable presentation across a website.

All CSS Properties You Need to Know to Build a Website

Here’s a list of the CSS properties you need to know to build a website:

Display: Flex

Flexbox, or the Flexible Box Layout, is a CSS3 layout model that allows you to design a complex layout structure in a more flexible and predictable way. It enables a container to alter its items’ width/height (and order) to best fill the available space (mostly to accommodate all kinds of display devices and screen sizes). A flex container expands items to fill available free space or shrinks them to prevent overflow.

display: flex; is particularly useful for aligning items horizontally or vertically within a container, building complex web layouts without using floats or positioning, and creating responsive designs that adjust smoothly to different screen sizes. Its impact on responsive design is significant, simplifying the creation of fluid layouts that adapt to any screen size with minimal effort.

CSS Properties

Margin

Margins are used to create space around elements, outside of any defined borders. Margins can control the spacing between elements on a page, helping to create visually appealing and well-organized layouts.

Margins can be used to separate sections of content, to push elements away from each other, or to center content within a container by setting equal margins on either side. For example, setting margin: 0 auto; on an element can center it horizontally within its parent container, contributing to a balanced and focused design.

Padding

Padding is the space between an element’s content and its border, unlike margin which is the space outside the element’s border. Padding affects the internal spacing of an element, making content within an element appear larger or smaller.

Padding can be used to increase the clickable area of links for better user interaction, to create space around the content inside a box, or to separate text from the edges of a container for improved readability.

CSS Properties

Background-Color

Background colors can be applied to elements to differentiate sections of a webpage, highlight important information, or simply improve aesthetics and readability. Choosing contrasting background colors can help elements stand out and guide the user’s eye through the layout.

Color

The color property specifies the color of the text inside an element. Using contrasting text colors can improve readability, draw attention to specific content, and contribute to the overall aesthetics of the site.

CSS Properties

Opacity

Opacity allows you to make elements partially transparent, creating depth in your designs and enabling overlay effects, such as modal dialogs or image overlays, without entirely blocking the content underneath.

Width and Height

Setting the width and height of elements is important for laying out your webpage. These properties can be specified in various units, including pixels, percentages, or ems, allowing for flexible and responsive design strategies.

Use relative units like percentages or viewport units (vw, vh) for width and height to create flexible layouts that adapt to the user’s screen size. This practice ensures that your design is accessible and user-friendly across devices.

Cursor: Pointer

The cursor: pointer; CSS property changes the cursor to a pointer hand icon when hovering over a link or clickable element, indicating to users that they can interact with it. This small visual cue can significantly enhance the usability and user experience of your website.

Font-Size

Font size is key to readability and the visual hierarchy of your content. Larger fonts draw attention and are used for headings, while smaller fonts are suitable for body text. Responsive units like ems or rems are recommended for text, as they allow the font size to adjust based on user settings or device screen size.

Font-Family

Font family plays an important role in conveying the tone and personality of your website. Selecting the right combination of fonts can enhance your website’s design coherence and readability. Consider web-safe fonts for maximum compatibility, or use web fonts for more variety and uniqueness in your design.
