I need a modern single-page SharePoint site restyled to match our detailed corporate style guide, which is already hosted inside SharePoint for easy reference. The job centres on creating and applying a bespoke theme/design—no forms or workflows are required. Scope • Build a clean, single modern page in SharePoint Online. • Craft a custom theme (colour palette, fonts, logo placement, and component styling) that mirrors the supplied style-guide assets. • Ensure responsiveness on desktop and mobile, keeping load times light. • Package the theme for easy re-use across other pages and document the steps so my internal team can reapply it. I will provide site access, the style guide link, and any brand assets upfront. Please outline your approach, timeline, and any past SharePoint theming work that shows you can translate strict brand guidelines into a polished user experience.
