Study Notes

Visual Design Considerations

Visualforce pages have the same appearance in both Salesforce Classic and Lightning Experience without adaptation.
Built-in Visualforce components retain Salesforce Classic styling, making pages feel out of place in Lightning Experience.
It is recommended to avoid adapting existing pages for Lightning Experience due to ongoing changes in its styling.

Styling Standard Components

Visualforce allows modest styling adjustments via style and styleClass attributes for individual components.
Custom stylesheets can be added as static resources to enhance the Visualforce page appearance.

Using Custom Stylesheets

Use <apex:stylesheet> to incorporate custom CSS from static resources for consistent styling across Visualforce pages.
When using Lightning Design System, include it directly in the markup instead of as a static resource for easier integration.

Lightning Experience Styling

For Lightning Experience, utilize specific markup to load custom stylesheets and ensure visual consistency.
Two main strategies exist to enhance existing pages: adjusting markup and updating styling rules in stylesheets.

Lightning Design System Overview

The Lightning Design System provides a comprehensive framework for creating apps that closely resemble Lightning Experience.
Key components: CSS framework, graphic assets, and Salesforce Sans font for cohesive design.
It is optimally utilized with new pages, as it necessitates a modern markup structure that Visualforce does not inherently support.

Considerations for Existing Pages

Incorporating Lightning Design System into existing Visualforce pages can be challenging due to markup differences.
Encouraged to avoid heavy reliance on internal HTML structures of Visualforce components as they are subject to change, which can break styling.

Overall Recommendations

For new development, always use the Lightning Design System to achieve a coherent look with Lightning Experience.
Modify existing styles cautiously, keeping in mind the potential pitfalls of depending on Visualforce's intrinsic elements.
