3 | Bringing back Internet Explorer’s Page Transitions thanks to the View Transition API

7 | [](./LICENSE)
8 | [](https://page-transitions.style/)
9 |
10 | ## Internet Explorer’s Page Transitions
11 |
12 | Microsoft Internet Explorer 4.0 and above featured a proprietary feature called [Interpage Transitions](https://learn.microsoft.com/en-us/previous-versions/windows/internet-explorer/ie-developer/platform-apis/ms532847(v=vs.85)?redirectedfrom=MSDN#interpage-transitions). It allowed you to specify [a transition effect](https://learn.microsoft.com/en-us/previous-versions/windows/internet-explorer/ie-developer/platform-apis/ms532853(v=vs.85)#transitions) to apply to the entire window as a Web page was loaded or exited.
13 |
14 | The feature worked best as of Microsoft Internet Explorer 5.5 which had a richer variety of optimized filters. The feature was eventually deprecated with the release of Windows Internet Explorer 9.
15 |
16 | Transitions were specified using a meta tag in the `
` of a web page. For example, the following snippet caused the [`Blinds` transition](https://learn.microsoft.com/en-us/previous-versions/windows/internet-explorer/ie-developer/platform-apis/ms532976(v=vs.85)) to play when the user loaded the page and caused a [`Slide` transition](https://learn.microsoft.com/en-us/previous-versions/windows/internet-explorer/ie-developer/platform-apis/ms533087(v=vs.85)) to play when the user exited the page.
17 |
18 | ```html
19 |
20 |
21 | ```
22 |
23 | Four events could create instances of interpage transitions: `Page-Enter`, `Page-Exit`, `Site-Enter`, and `Site-Exit`.
24 |
25 | ### The `RevealTrans` Filter
26 |
27 | The Page Transitions feature also came with a shorthand [the `DXImageTransform.Microsoft.RevealTrans` Filter](https://learn.microsoft.com/en-us/previous-versions/windows/internet-explorer/ie-developer/platform-apis/ms533085(v=vs.85)), which offered 23 predefined transitions mirrored from the effects found in Microsoft PowerPoint.
28 |
29 | Using one of these predefined effects was as easy as referring to its number – ranging from 0 to 22 – in the `revealTrans`’s filter `Transition` property. Using the value `23` randomly selected one of the 23 available effects.
30 |
31 | For example, using the following snippet caused Transition Effect number `7` – a vertical wipe from right to left – to play when the page was loaded.
32 |
33 | ```html
34 |
35 | ```
36 |
37 | Under the hood the `revealTrans(Transition=7)` mapped to a `DXImageTransform.Microsoft.Blinds(direction='left', bands=1)` effect.
38 |
39 | ## Requirements
40 |
41 | For Page Transitions to run, a browser with built-in Page Transitions support or a browser with support for the View Transition API + [Selective View Transitions with Active Types](https://drafts.csswg.org/css-view-transitions-2/#selective-vt) is required.
42 |
43 | - SPA
44 | - Chrome 125+
45 | - Safari 18.2
46 |
47 | - MPA
48 | - IE 5.5 - 8.0 _(built-in)_
49 | - Chrome 126+
50 | - Safari 18.2 _(buggy)_
51 |
52 | In browsers with no support for View Transitions, no effects will be run. The presence of `ie-page-transitions.css` won’t affect these browsers.
53 |
54 | ## Installation
55 |
56 | You can install this package from NPM:
57 |
58 | ```
59 | npm install ie-page-transitions
60 | ```
61 |
62 | Or, alternatively, load the files directly from a CDN:
63 |
64 | - unpkg: `https://unpkg.com/ie-page-transitions/` + `path/to/file.ext`
65 | - JSDelivr: `https://cdn.jsdelivr.net/npm/ie-page-transitions/` + `path/to/file.ext`
66 | - SkyPack: `https://cdn.skypack.dev/ie-page-transitions/` + `path/to/file.ext`
67 | - ESM.sh: `https://esm.sh/ie-page-transitions/` + `path/to/file.ext`
68 |
69 | ## Usage
70 |
71 | ### MPA
72 |
73 | 1. Enable Cross-Document View Transitions between two same-origin pages
74 |
75 | ```html
76 |
81 | ```
82 |
83 | 2. Include `ie-page-transitions.css` and `ie-page-transitions.mpa.js` on your pages.
84 |
85 | ```html
86 |
87 |
88 | ```
89 |
90 | *Note: The script **must** be loaded as a module and **must** be set to block rendering.*
91 |
92 | 3. Populate your pages with the meta tag(s) to define which effect(s) you want. _(See [Effect Configuration](#effect-configuration))_
93 |
94 | ```html
95 |
96 |
97 | ```
98 |
99 | ### SPA
100 |
101 | 1. Include `ie-page-transitions.css`
102 |
103 | ```html
104 |
105 | ```
106 |
107 | 2. Inject the meta tags to define which effect you want. _(See [Effect Configuration](#effect-configuration))_
108 |
109 | 3. If you have an entry effect on the first load, add the following render-blocking script to your page:
110 |
111 | ```html
112 |
116 | ```
117 |
118 | *Note: There is no real harm in adding this code when you don’t have an entry effect.*
119 |
120 | 4. Instead of calling `document.startViewTransition(callback)` call `PageTransitions.startViewTransition(callback)`.
121 |
122 | ```js
123 | import { startViewTransition } from 'https://unpkg.com/ie-page-transitions/src/ie-page-transitions.spa.js';
124 |
125 | // Randomize page layout (wrapped in a startViewTransition)
126 | $linkToNextPage.addEventListener('click', (e) => {
127 | e.preventDefault();
128 | startViewTransition(updateTheDOMSomehow);
129 | });
130 | ```
131 |
132 | ## Effect Configuration
133 |
134 | Just like IE, the transition can be configured by setting the proper values in the meta tag:
135 |
136 | - Set `http-equiv` to either `Page-Enter` or `Page-Exit` to define whether this is a page entry or page exit animation
137 | - Set the `Duration` to any number (double) to define the duration in seconds for the effect, eg. `2.0`
138 | - The duration values are limited to `0.5`, `1.0`, `1.5`, and `2.0`
139 | - Set the `Transition` to a number (int) to define which transition effect to use. There are 23 effects, from `0` to `22`. Using the value `23` randomly selects one of the 23 available effects.
140 |
141 | For example, to perform a pixel fade (aka. random dissolve) transition for 2 seconds upon entering a page, this markup is needed:
142 |
143 | ```html
144 |
145 | ```
146 |

175 | | ❌ | 22 | Random bars vertical | Horizontal Line Fade | DXImageTransform.Microsoft.RandomBars(orientation='vertical') |
176 | | ✅ | 23 | Random | Random | |
177 |
178 | ## Differences
179 |
180 | In Internet Explorer it was not possible to have one page define an exit transition and the other page an entry transition. When having both an exit and entry effect, the two would conflict, resulting in no transition happening at all.
181 |
182 | This library does not have the limitation. When both an exit and entry effect are set, these will run sequentially.
183 |
184 | To control the `background-color` of the `::view-transition` backdrop in between the exit and entry effects, set the `--page-transitions-backdrop-color` custom property on the `:root` element. If no color is set, the color `transparent` will be used.
