APEX_APPLICATION_PAGES

Rule Details

SonarQube Severity: Minor
Quality Area: Maintainability
Fixing Time: 5 mins Local-medium
Database Support: OracleDB (v7.3.4 +)
Profile: Strict
Available Since: Oct 1, 2026

Reason

CSS written inline on the page (in the page's Inline CSS attribute) is scattered across pages and hard to maintain; the same rules get copied around and can't be cached. Centralised styling in the Theme Roller or a static application file is easier to reuse and change in one place.

Move the CSS to the Theme Roller (for theme changes) or to a static application file referenced by the application.

Example

Non-Compliant Example

page 10 (
    name: Orders
    // ...
    css {
        inline: .t-Button--hot { background-color: #b00; }
    }
)

Compliant Solution - ★★★★★

page 10 (
    name: Orders
    // ...
    css {
        fileUrls: #APP_FILES#css/p10#MIN#.css
    }
)
