Salesforce User-Experience-Designer Exam With Confidence Using Practice Dumps

The designer should describe SLDS styling hooks as custom CSS properties that can easily style base and custom components. Styling hooks are placeholders in the SLDS style sheet that allow developers to customize the look and feel of their Lightning components by using the corresponding CSS custom properties. For example, the developer can change the background color of a button by setting the value of the --slds-c-button-brand-color-background custom property. Styling hooks are especially useful when working with web components and shadow DOM, as they enable component-level customizations without affecting the global styles. Styling hooks also provide consistency and performance benefits, as they leverage the SLDS design tokens and the native browser support for CSS custom properties. References:

The designer should describe the Salesforce Lightning Design System (SLDS) styling hooks as using standard CSS properties to easily style base and custom components. SLDS styling hooks allow developers to quickly and easily apply CSS classes to HTML elements, enabling consistent styling across both base and custom components. This allows developers to quickly and easily apply branding and styling to their Lightning Web Components, without needing to write custom CSS.

According to the Web Content Accessibility Guidelines (WCAG) 2.1, the minimum color contrast ratio for normal text is4.5:11. This means that the difference in brightness (luminance) between the text color and the background color should be at least 4.5 times.This ensures that the text is readable by people with moderately low vision, color deficiencies, or contrast sensitivity1. The contrast ratio can be calculated using the formula:

L2​+0.05L1​+0.05​

whereL1​is the relative luminance of the lighter color andL2​is the relative luminance of the darker color2.The relative luminance is a value between 0 and 1, where 0 is black and 1 is white2.The contrast ratio can range from 1:1 (white on white) to 21:1 (black on white)2.

The contrast ratio requirement for normal text is lower for larger text or bold text, as they are easier to read at lower contrast.For large text (18 point or 14 point bold), the minimum contrast ratio is3:11.For graphics and user interface components, such as form input borders, the minimum contrast ratio is also3:13.For level AAA conformance, the minimum contrast ratio for normal text is7:1and for large text is4.5:11.

To evaluate the color contrast ratio of a site, there are various tools available, such as theContrast Checkeror theContrast Ratiotool. These tools allow users to enter the text color and the background color and see the contrast ratio and whether it meets the WCAG guidelines. They also provide suggestions for improving the contrast ratio if needed.

The SLDS BEM naming convention consists of three parts: block, element, and modifier. A block is a standalone component that can be reused across projects, such as a button, a card, or a modal. An element is a part of a block that has no standalone meaning, such as a label, an icon, or a header. A modifier is a flag that changes the appearance or behavior of a block or an element, such as size, color, or state. The modifier is separated from the block or element by two hyphens (–), and can have a value separated by a single hyphen (-), such as .slds-button–brand or .slds-button–neutral. The class .slds–size-l-of-2 does not follow thisconvention because it has no block or element name before the modifier. It should be something like .slds-grid–size-l-of-2 or .slds-col–size-l-of-2. References:
