The current type scall of SonarQube is not flexible enough and create accessibility issues.
The current base font-size is 13px. Many information are currently using a 11px or 12px font-size because when the interface was designed we figured that these info were less important than the rest. As a consequence we had to go with a smaller font-size than 13px. This is something we want to avoid.
Examples in the interface:
The build string font-size in the activity page should be 13px instead of 11px. Using 13px for this info with the current type scale will remove that hierarchy.
The analysis date in the "Projects page" is currently 12px. Again we could change it to 13px but it would decrease the IA of the page.
For this reason we should revisit the current type scale and introduce one that is both more flexible and accessibility friendly. Since we want to keep a coherent information hierarchy it's important to keep in mind that the scale should be adjusted as a whole.
