CSS Layout Techniques Quiz

Responsive Web Design

• Ethan Marcotte coined the term 'responsive web design'.
• The core tenets of Responsive Web Design are: flexible grids, flexible images, and media queries.

Web Development

• Optimizing for mobile first in web development is beneficial because it allows for a more focused and efficient design process.
• Flex items in a Flexbox container behave based on their initial behavior, and can change layout depending on the available space.
• Using a single large image scaled down for responsiveness can lead to slow page loading and poor user experience.
• The 'srcset' and 'sizes' attributes can help with responsive images by allowing for multiple image sizes and sources to be defined.
• Responsive Typography involves adjusting font sizes and styles based on the screen size and device.

CSS

• The 'fr' unit in CSS Grid Layout is used to define a fractional unit of space.
• The 'viewport meta tag' is important in responsive design because it controls the zooming and scaling of a webpage on different devices.
• Media queries enable responsive design to run a series of tests and apply CSS selectively based on user needs.

Layout and Design

• Fluid CSS uses units of measurement such as percentages, em, and rem to create responsive layouts.
• The core tenet of responsive design that allows designers not to target every possible device size is the use of flexible grids and media queries.
• The oldest method among all layout technologies is the table layout.
• It is impossible to target every possible device size in responsive design using a pixel-perfect layout approach because of the diversity of devices and screen sizes.

SEO and Accessibility

• In 2018, Google changed the way content should be managed for SEO, prioritizing mobile-first indexing.
• To determine where to focus on a website, analytics should be used to identify areas of high user engagement.
• Accessibility-friendly websites require proper use of semantic HTML, ARIA attributes, and keyboard navigation.

• The 'alt' attribute can be omitted without affecting the markup in HTML5.
• The 'type' attribute is not necessary in HTML5 according to the text.
• The author's personal preference is to write HTML markup in lowercase.
• Symantec recommends using HTML elements such as 'header', 'nav', 'main', and 'section' for coding.
• The 'video' tag is commonly used to link to a video file.
• To ensure default playback controls for a video in HTML, the 'controls' attribute should be used.
• A 'track' element can be inserted between the opening and closing tag of a 'video' element in HTML.
• The 'poster' attribute is used to define a poster frame for a video.
