Keywords

💡Web Accessibility

Web accessibility refers to the inclusive practice of making websites usable by people with disabilities. It is a core theme of the video, emphasizing the importance of designing websites to be accessible to everyone, regardless of their physical or cognitive abilities. The script mentions that a significant percentage of the population has some form of disability, highlighting the need for accessible web design.

💡Disabilities

Disabilities are physical or mental conditions that limit a person's movements, senses, or activities. The video discusses various types of disabilities, particularly visual impairments, to stress the importance of accessibility in web design. For instance, the script cites a report indicating that nearly one million people in Spain have severe vision problems.

💡Visual Impairment

Visual impairment is a disability that affects a person's ability to see, which can range from complete blindness to having a limited field of vision. The video uses the example of the Olivenza 2010 report to illustrate the prevalence of visual impairments, nearly affecting one million people in Spain, to underscore the need for accessible web design.

💡Legislation

Legislation in the context of the video refers to laws and regulations that mandate web accessibility. The video mentions that in Spain, all public administration websites must be accessible to people with disabilities since January 1, 2009. This highlights the legal framework that supports the push for web accessibility.

💡罚款 (Fines)

Fines are monetary penalties imposed for non-compliance with laws or regulations. The video discusses the potential fines for non-compliance with web accessibility laws, such as the possibility of fines up to one million euros. This serves as a deterrent and emphasizes the seriousness of web accessibility as a legal requirement.

💡Design Myths

Design myths are misconceptions about web design, such as the belief that accessible websites must be unattractive or boring. The video dispels this myth by citing examples of accessible websites with high-quality designs, like the official website of the Swedish government, which is both accessible and aesthetically pleasing.

💡Responsive Web Design

Responsive web design is an approach to web design that makes web pages render well on a variety of devices and window or screen sizes. The video explains how an outdated website of a university had a fixed design for an 800-pixel-wide screen, which was not responsive and led to wasted space on mobile devices. In contrast, the video's course website is designed to be accessible across different resolutions and devices.

💡Positioning

Positioning in the context of web design refers to the practice of optimizing a website to rank high in search engine results. The video suggests that web accessibility can improve a site's positioning because search engines like Google and Bing behave like 'blind users,' favoring accessible websites.

💡Screen Resolution

Screen resolution is the number of pixels that a screen can display in width and height. The video uses the example of an old university website designed for an 800-pixel-wide screen, which was not suitable for modern devices with higher resolutions, illustrating the need for responsive design that accommodates various screen resolutions.

💡Text-Only Version

A text-only version of a website is a simplified version that includes only text content, often perceived as accessible. However, the video clarifies that offering a text-only version does not equate to true accessibility, which requires comprehensive design considerations to accommodate all users.

💡World Health Organization (WHO)

The World Health Organization is a specialized agency of the United Nations responsible for international public health. The video cites a WHO report indicating that over a billion people worldwide live with some form of disability, nearly 200 million of whom experience considerable difficulties, highlighting the global relevance of web accessibility.
