The Gordon Institute of Business Science redesigned its Corporate Finance Techniques PDBA course around a foundational commitment to universal accessibility. Every piece of mathematically complex content, including time-value-of-money formulas, annuity calculations, and capital budgeting models, was rebuilt as native, interactive HTML using LaTeX and MathJax, replacing inaccessible static PDFs and iFrame-hosted lessons. All custom components were developed to WCAG 2.1 standards, with full keyboard navigation, ARIA roles, focus management, and reduced-motion support. The result is a course in which every learner, regardless of device, assistive technology, or learning background, engages with technically demanding financial content on genuinely equal terms.
