Consistent Button & Font Styling Guide

Questions answered by this guide

• ?Why do my buttons look slightly different from slide to slide?
• ?How many fonts should one course use?
• ?How do I fix inconsistent styling across a whole course?
• ?Does A11yCheck check for styling consistency?

What you'll learn

• Button style drift usually means different border-radius values across slides, a rounded button next to a square one
• Font drift usually means more than two distinct font families in a course meant to use one consistent typography system
• Both are almost always caused by copy-pasting slides from different sources, not a single deliberate choice

What's inside

Instructional designers doing a final styling pass, especially on courses built from templates or reused slides

Why it matters

Nothing about a mismatched button radius or an extra font family breaks functionality, but a learner notices it immediately, the same way a document with three different fonts reads as unpolished even if every sentence is well written. Visual consistency is one of the fastest, cheapest signals of a course that was actually finished carefully.

When you'll encounter this

• You've copy-pasted a slide from another course, template, or an older project.
• Multiple people built different sections of the same course.
• A course has been edited and re-edited over a long period, with styling choices drifting slide by slide.

Example

Best practices

• Define button and text styles once, in the Slide Master, and apply them everywhere rather than styling each button or text box individually.
• Limit a course to one, or at most two, real font families, heading and body, matching the practice most professional documents and courses already follow.
• When copy-pasting a slide from another course or template, deliberately re-apply the current course's styles rather than assuming it will inherit them automatically.
• Do a dedicated visual consistency pass at the end of a build, scanning slide thumbnails side by side often reveals drift that's easy to miss slide by slide.

Common mistakes

• Styling each button individually instead of from a shared Slide Master, making drift easy to introduce and hard to catch.
• Accumulating more than two font families over a course's editing history without ever consolidating them.
• Copy-pasting a slide from another project and never checking whether its styling matches the current course.

Practical checklist

• All buttons share the same corner radius and style, applied from the Slide Master, not set individually.
• The course uses no more than two real font families, one for headings, one for body text.
• Any slide copy-pasted from another source has been checked against the current course's styling, not left as-is.
• A dedicated visual consistency pass, thumbnails side by side, was done before publishing.

Frequently asked questions

Summary

Inconsistent button styling and too many fonts are two of the most visible, most common course-quality problems, almost always caused by copy-pasted or reused slides carrying their old styling along with them. Defining styles once, in the Slide Master, and applying them everywhere is what actually prevents this rather than manually matching each slide.
