This feature within the now-discontinued Microsoft Expression Web allowed users to preview how different fonts would render on their webpages directly within the design environment. For instance, a designer could select a specific paragraph of text and then cycle through available fonts to assess their visual impact without needing to constantly refresh a browser window.
The availability of this font preview functionality streamlined the web design process by facilitating rapid prototyping and aesthetic decision-making. It provided immediate feedback on font choices, which could significantly improve the overall readability and visual appeal of a website. Previously, designers might have relied on external font viewers or manual browser testing, leading to a less efficient workflow. This feature contributed to a more WYSIWYG (“What You See Is What You Get”) design experience.
