Please review a change to improve the target highlight for javadoc member details sections.
Instead of highlighting the member header by changing its background color, we now add a subtle accent bar to the left side of the header. The bar is implemented as `box-shadow`, is just outside the header element and does not cause a layout shift. It uses the theme's link color with an alpha of 70%, which seems to work well in both themes. The accent bar is wide enough to be noticeable, but nowhere near as distractive as the old highlight, and brings our documentation more in line with modern documentation/UI patterns. Sample docs for the `java.lang` package are [available here](https://cr.openjdk.org/~hannesw/8383906/api.00/java.base/java/lang/Object.html#hashCode()). --------- - [x] I confirm that I make this contribution in accordance with the [OpenJDK Interim AI Policy](https://openjdk.org/legal/ai). ------------- Commit messages: - 8383906: Target highlight in member details is too aggressive Changes: https://git.openjdk.org/jdk/pull/31052/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=31052&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8383906 Stats: 6 lines in 1 file changed: 0 ins; 5 del; 1 mod Patch: https://git.openjdk.org/jdk/pull/31052.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/31052/head:pull/31052 PR: https://git.openjdk.org/jdk/pull/31052
