Create responsive HTML output

Overview

Use responsive SVG layout settings when exporting classic HTML so the slide graphic can fit its containing area. This helps integrate slide output into a page whose width changes. Your hosting page controls the surrounding layout and browser viewport settings.

Usage example (C#)

Install Aspose.Slides for .NET before running this standalone example. Export a generated slide using the responsive HTML controller. Its slide viewport scales with the browser width while preserving the slide’s proportions.

using System;
using Aspose.Slides;
using Aspose.Slides.Export;

using var presentation = new Presentation();
var shape = presentation.Slides[0].Shapes.AddAutoShape(ShapeType.Rectangle, 40, 40, 500, 140);
shape.AddTextFrame("Sample slide");
var controller = new ResponsiveHtmlController();
var options = new HtmlOptions { HtmlFormatter = HtmlFormatter.CreateCustomFormatter(controller) };
presentation.Save("responsive.html", SaveFormat.Html, options);
presentation.Save("source.pptx", SaveFormat.Pptx);

FAQ

Does this also make the HTML5 player responsive?

The responsive SVG options belong to the classic HTML path. HTML5 player sizing is a separate behavior.

How does responsive HTML scale to a narrow viewport?

The exported slide scales to fit the available width while retaining its slide coordinate system and proportions.

Does responsive output reflow slide objects like ordinary HTML text?

No. It scales the slide view; it does not turn the slide into independently reflowing paragraphs and objects.
