CSS滚动snap幻灯片支持实时编码

本文展示了使用CSS卷轴快照创建响应迅速，可共享的无JavaScript幻灯片牌，即使在现场场地也是实时编码演示文稿的理想选择。该教程通过可编辑的CSS演示构建了一个基于编码的甲板，重点是效率和可访问性。

虚拟演示文稿彻底改变了内容的交付，为演示者提供了灵活性，并具有多个监视器，以进行实时编码期间的屏幕外调整。该教程通过仅使用Web标准和现代CSS创建可比的体验来弥合虚拟和面对面事件之间的差距。

探索的关键技术包括CSS卷轴快照，计数器，网格布局， contenteditable属性，自定义属性，HSL主题，渐变文本和样式

The HTML structure utilizes an ordered list (<ol></ol>) with the ID "slides," each list item (<li>) representing a slide with appropriate class modifiers (e.g., slide--text, slide--title, slide--demo). The contenteditable attribute enables live editing of CSS within the demo slides.

Base styles establish a consistent look and feel using custom properties (--theme-hue, --theme-saturation) for color theming with HSL. Gradient backgrounds enhance the title slides. The demo slide incorporates a resizable .style container housing an inline <style></style> element for live-editable CSS, and a .demo container for the preview. The contenteditable="true" attribute on the <style></style> element is crucial for the live-coding functionality. Note that browser compatibility varies; Firefox offers the most complete live-editing support.

Code highlighting is achieved using linear-gradients and -webkit-text-fill-color and -webkit-background-clip properties, with custom properties controlling highlighted lines. Utility classes (highlight--rule-only, highlight--none) provide additional highlighting control.

CSS scroll snap (scroll-snap-type, scroll-snap-align, scroll-snap-stop) enables smooth, one-slide-at-a-time navigation. A media query adapts the layout for smaller viewports, switching from horizontal to vertical scrolling. Slide numbers are implemented using CSS counters and data attributes for enhanced visual organization.

The final slide deck is fully responsive and adaptable to various screen sizes, offering a seamless presentation experience across different devices and browsers. While full syntax highlighting requires JavaScript, this approach prioritizes simplicity and accessibility. The tutorial concludes with a link to a completed example and additional resources for further exploration of CSS scroll snap.
