Dynamic Actions are a feature that allows the UX Designer to customize the actions that appear on the Highlights panel of a Lightning record page based on criteria such as record status, user profile, or field value. This way, the UX Designer can declutter the Highlights panel and show only the relevant actions for each record. Dynamic Actions can be configured in the Lightning App Builder instead of the page layout editor, which gives more flexibility and control to the UX Designer. References:

Inclusive design and accessible design are both important aspects of creating products and services that are usable and enjoyable for everyone, regardless of their abilities, preferences, or contexts. However, they are not the same thing. Inclusive design is a methodology that involves designing with and for people who have a range of diverse needs and experiences. Inclusive design aims to create solutions that are not only accessible, but also equitable, respectful, and empowering for all users12. Accessible design is based on guidelines that help ensure that products and services can be perceived, understood, operated, and interacted with by people with disabilities. Accessible design follows standards such as the Web Content Accessibility Guidelines (WCAG), which provide technical specifications and best practices for making web content accessible34. Inclusive design and accessible design are not mutually exclusive, but rather complementary. Inclusive design can help inform accessible design by providing insights and feedback from diverse users and stakeholders. Accessible design can help support inclusive design by providing a baseline of quality and compliance for products and services. By applying both inclusive design and accessible design, UX designers can create more inclusive, accessible, and delightful experiences for everyone. References: Inclusive Design & Accessibility – Salesforce Designer – Medium, Product Accessibility and Inclusive Design - Salesforce.com, Learn the Elements of an Accessible Webpage Unit | Salesforce Trailhead, How Can Tech Be More Inclusive?

The Salesforce Lightning Design System (SLDS) is a CSS framework that helps designers and developers create applications with the look and feel of Lightning Experience. SLDS provides a library of design tokens, icons, components, utilities, and patterns that can be used to build consistent, responsive, and accessible user interfaces1. One of the features that SLDS provides for designers and developers is semantic and accessible component markup. Semantic markup means using HTML elements that describe the meaning and structure of the content, rather than just the presentation. For example, using 

 for a main heading, 

 for a paragraph, or  for a button. Semantic markup helps to improve the readability, maintainability, and SEO of the code2. Accessible markup means using HTML attributes and techniques that enhance the usability and accessibility of the content for people with disabilities. For example, using aria-label to provide a descriptive label for an element, role to indicate the function of an element, or tabindex to control the keyboard focus order. Accessible markup helps to ensure that the content can be perceived, understood, operated, and interacted with by people using assistive technologies, such as screen readers, keyboards, or voice commands3. SLDS provides semantic and accessible markup for its components, which are reusable UI elements that can be customized and composed to create complex interfaces. SLDS components follow the Web Content Accessibility Guidelines (WCAG), which are the international standards for web accessibility4. SLDS components also use the BEM (Block Element Modifier)naming convention, which is a methodology for creating clear and consistent class names for CSS selectors5. By using SLDS components, designers and developers can create user interfaces that are not only visually appealing, but also meaningful and accessible for everyone. References: Introduction to the Salesforce Lightning Design System, Semantic HTML: How to Structure Web Pages, Accessible Rich Internet Applications (WAI-ARIA), Web Content Accessibility Guidelines (WCAG) Overview, BEM — Block Element Modifier
