This commit addresses an issue in Chromium on Linux and Windows where
the appearance of a vertical scrollbar causes unexpected horizontal
layout shifts. This behavior typically occurs when the window is
resized, a card is opened or a script is selected, resulting in content
being pushed to the left.
The solution implemented involves using `scrollbar-gutter: stable` to
ensure space is always allocated for the scrollbar, thus preventing any
shift in the page layout. This fix primarily affects Chromium-based
browsers on Linux and Windows. It has no impact on Firefox on any
platform, or any browser on macOS (including Chromium). Because these
render the scrollbar as an overlay, and do not suffer from this issue.
Steps to reproduce the issue using Chromium browser on Linux/Windows:
1. Open the app with a height large enough where a vertical scrollbar is
not visible.
2. Resize the window to a height that triggers a vertical scrollbar.
3. Notice the layout shift as the body content moves to the right.
Changes:
- Add a CSS mixin to handle scrollbar gutter allocation with a fallback.
- Add support for modal dialog background lock to handle
`scrollbar-gutter: stable;` in calculations to avoid layout shift when
a modal is open.
- Add E2E test to avoid regression.
- Update DevToolkit to accommodate new scrollbar spacing.
This commit improves UI consistency. It also improves maintainability by
removing "magic values" in favor of standardized spacing throughout the
application.
- Adjust spacing variables to match the convention.
- Add `_spacing.scss` to define a centralized set of spacing variables, both
absolute and relative, to standardize the spacing throughout the application.
This new approach ensures a consistent spacing logic across all components and
layouts, facilitating easier maintenance and scalability of the styling codebase.
- Update various SCSS styles to utilize the new spacing variables. This change
harmonizes the spacing across different parts of the application, aligning with
the new design system's principles.
- Slightly adjust existing padding/margin/gaps for better consistency.
Other supporting changes per component:
- RatingCircle: Update style names to match convention and simplify
hacky way to inject circle width value through CSS variables. Add
tests for the new behavior and refactor existing tests for easier
extensibility.
- TheFooter: Add small gap when footer items wrap.
- HiearchicalTreeNode: Refactor variables to separate caret size clearly
from padding applied.
- App: Make padding responsive as initial behavior of v0.13.0 before
5d940b57ef.
- ModalDialog: Use responsive absolute values instead of percentage.
- HorizontalResizeSlider:
- Use `v-bind` instead of hacky way to inject SCSS values through variables.
- Remove `verticalMargin` property to simplify its styling.
- Move `src/presentation/assets/styles/components/_card.scss` closer to
components that it styles. Update structure documentation.
The centralization of spacing definitions will aid in future design
adjustments, ensuring that updates to spacing can be made swiftly and
uniformly across the application. It's a step towards a more maintainable
and scalable frontend architecture.
This commit fixes inconsistent tooltip styling by setting the font
explicitly on the tooltip container to ensure uniform tooltip fonts.
As tooltip is rendered inside the parent elements' DOM, styling parent
element's font was also styling the font's font due to style
propogation, but setting fonts explicitly on tooltip ensure this does
not happen.
This commit centralizes the styling of key UI elements across the
project to ensure:
- Consistent look and feel.
- Enhanced code reusability.
- Simpified maintenance, improving development speed.
It establishes a uniform foundation that can be leveraged across
different parts of the project, even enabling the styling to be shared
across different websites (supporting issue #49).
Key changes:
- Apply the following shared styles globally:
* Styling of code, blockquotes, superscripts, horizontal rules and
anchors.
* Vertical and horizontal spacing.
- Segregate base styling into dedicated SCSS files for clearer structure
and increased maintainability.
- Remove custom styling from affected components, enabling global style
reuse for visual uniformity, reduced redundancy, and enhanced
semantics.
Other supporting changes:
- Rename `globals.scss` to `base.scss` for better clarity.
- Add `.editorconfig` for `.scss` files to ensure consistent whitespace
usage.
- Remove `2` file from the project root, that was included in the source
code by mistake.
- Remove unused font-face imports
