本文展示了使用CSS卷軸快照創(chuàng)建響應(yīng)迅速，可共享的無JavaScript幻燈片牌，即使在現(xiàn)場場地也是實時編碼演示文稿的理想選擇。該教程通過可編輯的CSS演示構(gòu)建了一個基于編碼的甲板，重點是效率和可訪問性。

虛擬演示文稿徹底改變了內(nèi)容的交付，為演示者提供了靈活性，并具有多個監(jiān)視器，以進(jìn)行實時編碼期間的屏幕外調(diào)整。該教程通過僅使用Web標(biāo)準(zhǔn)和現(xiàn)代CSS創(chuàng)建可比的體驗來彌合虛擬和面對面事件之間的差距。

探索的關(guān)鍵技術(shù)包括CSS卷軸快照，計數(shù)器，網(wǎng)格布局， contenteditable屬性，自定義屬性，HSL主題，漸變文本和樣式

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.
