WIP: styling for date separator

apart from gap, which doesn't have date

since we add a container when the date separator needs to be shown, and
we don't want to rerender the whole tile, we always render timeline
tiles with a DIV rather than an LI (same for the UL).

-# Theming Documentation
-## Basic Architecture
-A **theme collection** in Hydrogen is represented by a `manifest.json` file and a `theme.css` file.
-The manifest specifies variants (eg: dark,light ...) each of which is a **theme** and maps to a single css file in the build output.
-
-Each such theme is produced by changing the values of variables in the base `theme.css` file with those specified in the variant section of the manifest:
-
-![](images/theming-architecture.png)
-
-More in depth explanations can be found in later sections.
-
-## Structure of `manifest.json`
-[See theme.ts](../src/platform/types/theme.ts)
-
-## Variables
-CSS variables specific to a particular variant are specified in the `variants` section of the manifest:
-```json=
- "variants": {
-     "light": {
-         ...
-         "variables": {
-             "background-color-primary": "#fff",
-             "text-color": "#2E2F32",
-         }
-     },
-      "dark": {
-         ...
-        "variables": {
-            "background-color-primary": "#21262b",
-            "text-color": "#fff",
-        }
-    }
- }
-```
-
-These variables will appear in the css file (theme.css):
-```css=
-body {
-    background-color: var(--background-color-primary);
-    color: var(--text-color);
-}
-```
-
-During the build process, this would result in the creation of two css files (one for each variant) where the variables are substitued with the corresponding values specified in the manifest:
-
-*element-light.css*:
-```css=
-body {
-    background-color: #fff;
-    color: #2E2F32;
-}
-```
-
-*element-dark.css*:
-```css=
-body {
-    background-color: #21262b;
-    color: #fff;
-}
-```
-
-## Derived Variables
-In addition to simple substitution of variables in the stylesheet, it is also possible to instruct the build system to first produce a new value from the base variable value before the substitution.
-
-Such derived variables have the form `base_css_variable--operation-arg` and can be read as:
-apply `operation` to `base_css_variable` with argument `arg`.
-
-Continuing with the previous example, it possible to specify:
-```css=
-.left-panel {
-    /* background color should be 20% more darker
-       than background-color-primary */
-    background-color: var(--background-color-primary--darker-20);
-}
-```
-
-Currently supported operations are:
-
-| Operation | Argument | Operates On |
-| -------- | -------- | -------- |
-| darker     | percentage | color |
-| lighter     | percentage | color |
-
-## Aliases
-It is possible give aliases to variables in the `theme.css` file:
-```css=
-:root {
-    font-size: 10px;
-    /* Theme aliases */
-    --icon-color: var(--background-color-secondary--darker-40);
-}
-```
-It is possible to further derive from these aliased variables:
-```css=
-div {
-    background: var(--icon-color--darker-20);
-    --my-alias: var(--icon-color--darker-20);
-    /* Derive from aliased  variable */
-    color: var(--my-alias--lighter-15);
-}
-```
-
-
-## Colorizing svgs
-Along with a change in color-scheme, it may be necessary to change the colors in the svg icons and images. 
-This can be done by supplying the preferred colors with query parameters:
-`my-awesome-logo.svg?primary=base-variable-1&secondary=base-variable-2`  
-
-This instructs the build system to colorize the svg with the given primary and secondary colors.
-`base-variable-1` and `base-variable-2` are the css-variables specified in the `variables` section of the manifest.
-
-For colorizing svgs, the source svg must use `#ff00ff` as the primary color and `#00ffff` as the secondary color:
-
-  
-
-| ![](images/svg-icon-example.png) | ![](images/coloring-process.png) |
-| :--: |:--: |
-| **original source image** | **transformation process** |
-
-## Creating your own theme variant in Hydrogen
-If you're looking to change the color-scheme of the existing Element theme, you only need to add your own variant to the existing `manifest.json`.
-
-The steps are fairly simple:
-1. Copy over an existing variant to the variants section of the manifest.
-2. Change `dark`, `default` and `name` fields.
-3. Give new values to each variable in the `variables` section.
-4. Build hydrogen.
-
-## Creating your own theme collection in Hydrogen
-If a theme variant does not solve your needs, you can create a new theme collection with a different base `theme.css` file.
-1. Create a directory for your new theme-collection under `src/platform/web/ui/css/themes/`.
-2. Create `manifest.json` and `theme.css` files within the newly created directory.
-3. Populate `manifest.json` with the base css variables you wish to use.
-4. Write styles in your `theme.css` file using the base variables, derived variables and colorized svg icons.
-5. Tell the build system where to find this theme-collection by providing the location of this directory to the `themeBuilder` plugin in `vite.config.js`:
-```json=
-...
-themeBuilder({
-    themeConfig: {
-        themes: {
-            element: "./src/platform/web/ui/css/themes/element",
-            awesome: "path/to/theme-directory"
-        },
-        default: "element",
-    },
-    compiledVariables,
-}),
-...
-```
-6. Build Hydrogen.
-
-## Changing the default theme
-To change the default theme used in Hydrogen, modify the `defaultTheme` field in `config.json` file (which can be found in the build output):
-```json=
-"defaultTheme": {
-    "light": theme-id,
-    "dark": theme-id
-}
-```
-
-Here *theme-id* is of the form `theme-variant` where `theme` is the key used when specifying the manifest location of the theme collection in `vite.config.js` and `variant` is the key used in variants section of the manifest.
-
-Some examples of theme-ids are `element-dark` and `element-light`.  
-
-To find the theme-id of some theme, you can look at the built-asset section of the manifest in the build output.
-
-This default theme will render as "Default" option in the theme-chooser dropdown. If the device preference is for dark theme, the dark default is selected and vice versa.
-
-**You'll need to reload twice so that Hydrogen picks up the config changes!**
-
-# Derived Theme(Collection)
-This allows users to theme Hydrogen without the need for rebuilding. Derived theme collections can be thought of as extensions (derivations) of some existing build time theme. 
-
-## Creating a derived theme:
-Here's how you create a new derived theme:
-1. You create a new theme manifest file (eg: theme-awesome.json) and mention which build time theme you're basing your new theme on using the `extends` field. The base css file of the mentioned theme is used for your new theme.
-2. You configure the theme manifest as usual by populating the `variants` field with your desired colors.
-3. You add your new theme manifest to the list of themes in `config.json`.
-
-Refresh Hydrogen twice (once to refresh cache, and once to load) and the new theme should show up in the theme chooser.
-
-## How does it work?
-
-For every theme collection in hydrogen, the build process emits a runtime css file which like the built theme css file contains variables in the css code. But unlike the theme css file, the runtime css file lacks the definition for these variables:
-
-CSS for the built theme:
-```css
-:root {
-    --background-color-primary: #f2f20f;
-}
-
-body {
-    background-color: var(--background-color-primary);
-}
-```
-and the corresponding runtime theme:
-```css
-/* Notice the lack of definiton for --background-color-primary here! */
-body {
-    background-color: var(--background-color-primary);
-}
-```
-
-When hydrogen loads a derived theme, it takes the runtime css file of the extended theme and dynamically adds the variable definition based on the values specified in the manifest. Icons are also colored dynamically and injected as variables using Data URIs.

-## IView components
-
-The [interface](https://github.com/vector-im/hydrogen-web/blob/master/src/platform/web/ui/general/types.ts) adopted by view components is agnostic of how they are rendered to the DOM. This has several benefits:
- - it allows Hydrogen to not ship a [heavy view framework](https://bundlephobia.com/package/react-dom@18.2.0) that may or may not be used by its SDK users, and also keep bundle size of the app down.
- - Given the interface is quite simple, is should be easy to integrate this interface into the render lifecycle of other frameworks.
- - The main implementations used in Hydrogen are [`ListView`](https://github.com/vector-im/hydrogen-web/blob/master/src/platform/web/ui/general/ListView.ts) (rendering [`ObservableList`](https://github.com/vector-im/hydrogen-web/blob/master/src/observable/list/BaseObservableList.ts)s) and [`TemplateView`](https://github.com/vector-im/hydrogen-web/blob/master/src/platform/web/ui/general/TemplateView.ts) (templating and one-way databinding), each only a few 100 lines of code and tailored towards their specific use-case. They work straight with the DOM API and have no other dependencies.
- - a common inteface allows us to mix and match between these different implementations (and gradually shift if need be in the future) with the code.
-
-## Templates
-
-### Template language
-
-Templates use a mini-DSL language in pure javascript to express declarative templates. This is basically a very thin wrapper around `document.createElement`, `document.createTextNode`, `node.setAttribute` and `node.appendChild` to quickly create DOM trees. The general syntax is as follows:
-```js
-t.tag_name({attribute1: value, attribute2: value, ...}, [child_elements]);
-t.tag_name(child_element);
-t.tag_name([child_elements]);
-```
-**tag_name** can be [most HTML or SVG tags](https://github.com/vector-im/hydrogen-web/blob/master/src/platform/web/ui/general/html.ts#L102-L110).
-
-eg:
-Here is an example HTML segment followed with the code to create it in Hydrogen.
-```html
-<section class="main-section">
-    <h1>Demo</h1>
-    <button class="btn_cool">Click me</button>
-</section>
-```
-```js
-t.section({className: "main-section"},[
-    t.h1("Demo"), 
-    t.button({className:"btn_cool"}, "Click me")
-]);
-```
-
-All these functions return DOM element nodes, e.g. the result of `document.createElement`.
-
-### TemplateView
-
-`TemplateView` builds on top of templating by adopting the IView component model and adding event handling attributes, sub views and one-way databinding.
-In views based on `TemplateView`, you will see a render method with a `t` argument.  
-`t` is `TemplateBuilder` object passed to the render function in `TemplateView`. It also takes a data object to render and bind to, often called `vm`, short for view model from the MVVM pattern Hydrogen uses.
-
-You either subclass `TemplateView` and override the `render` method:
-```js
-class MyView extends TemplateView {
-    render(t, vm) {
-        return t.div(...);
-    }
-}
-```
-
-Or you pass a render function to `InlineTemplateView`:
-```js
-new InlineTemplateView(vm, (t, vm) => {
-    return t.div(...);
-});
-```
-
-**Note:** the render function is only called once to build the initial DOM tree and setup bindings, etc ... Any subsequent updates to the DOM of a component happens through bindings.
-
-#### Event handlers
-
-Any attribute starting with `on` and having a function as a value will be attached as an event listener on the given node. The event handler will be removed during unmounting.
-
-```js
-t.button({onClick: evt => {
-    vm.doSomething(evt.target.value);
-}}, "Click me");
-```
-
-#### Subviews
-
-`t.view(instance)` will mount the sub view (can be any IView) and return its root node so it can be attached in the DOM tree.
-All subviews will be unmounted when the parent view gets unmounted.
-
-```js
-t.div({className: "Container"}, t.view(new ChildView(vm.childViewModel)));
-```
-
-#### One-way data-binding
-
-A binding couples a part of the DOM to a value on the view model. The view model emits an update when any of its properties change, to which the view can subscribe. When an update is received by the view, it will reevaluate all the bindings, and update the DOM accordingly.
-
-A binding can appear in many places where a static value can usually be used in the template tree.
-To create a binding, you pass a function that maps the view value to a static value.
-
-##### Text binding
-
-```js
-t.p(["I've got ", vm => vm.counter, " beans"])
-```
-
-##### Attribute binding
-
-```js
-t.button({disabled: vm => vm.isBusy}, "Submit");
-```
-
-##### Class-name binding
-```js
-t.div({className: {
-    button: true,
-    active: vm => vm.isActive
-}})
-```
-##### Subview binding
-
-So far, all the bindings can only change node values within our tree, but don't change the structure of the DOM. A sub view binding allows you to conditionally add a subview based on the result of a binding function.
-
-All sub view bindings return a DOM (element or comment) node and can be directly added to the DOM tree by including them in your template.
-
-###### map
-
-`t.mapView` allows you to choose a view based on the result of the binding function:
-
-```js
-t.mapView(vm => vm.count, count => {
-    return count > 5 ? new LargeView(count) : new SmallView(count);
-});
-```
-
-Every time the first or binding function returns a different value, the second function is run to create a new view to replace the previous view.
-
-You can also return `null` or `undefined` from the second function to indicate a view should not be rendered. In this case a comment node will be used as a placeholder.
-
-There is also a `t.map` which will create a new template view (with the same value) and you directly provide a render function for it:
-
-```js
-t.map(vm => vm.shape, (shape, t, vm) => {
-    switch (shape) {
-        case "rect": return t.rect();
-        case "circle": return t.circle();
-    }
-})
-```
-
-###### if
-
-`t.ifView` will render the subview if the binding returns a truthy value:
-
-```js
-t.ifView(vm => vm.isActive, vm => new View(vm.someValue));
-```
-
-You equally have `t.if`, which creates a `TemplateView` and passes you the `TemplateBuilder`:
-
-```js
-t.if(vm => vm.isActive, (t, vm) => t.div("active!"));
-```
-
-##### Side-effects
-
-Sometimes you want to imperatively modify your DOM tree based on the value of a binding.
-`mapSideEffect` makes this easy to do:
-
-```js
-let node = t.div();
-t.mapSideEffect(vm => vm.color, (color, oldColor) => node.style.background = color);
-return node;
-```
-
-**Note:** you shouldn't add any bindings, subviews or event handlers from the side-effect callback,
-the safest is to not use the `t` argument at all.
-If you do, they will be added every time the callback is run and only cleaned up when the view is unmounted.
-
-#### `tag` vs `t`
-
-If you don't need a view component with data-binding, sub views and event handler attributes, the template language also is available in `ui/general/html.js` without any of these bells and whistles, exported as `tag`. As opposed to static templates with `tag`, you always use
-`TemplateView` as an instance of a class, as there is some extra state to keep track (bindings, event handlers and subviews).
-
-Although syntactically similar, `TemplateBuilder` and `tag` are not functionally equivalent.  
-Primarily `t` **supports** bindings and event handlers while `tag` **does not**. This is because to remove event listeners, we need to keep track of them, and thus we need to keep this state somewhere which
-we can't do with a simple function call but we can insite the TemplateView class.
-
-```js
-    // The onClick here wont work!!
-    tag.button({className:"awesome-btn", onClick: () => this.foo()});
-
-class MyView extends TemplateView {
-    render(t, vm){
-        // The onClick works here.
-        t.button({className:"awesome-btn", onClick: () => this.foo()});
-    }
-}
-```
-
-## ListView
-
-A view component that renders and updates a list of sub views for every item in a `ObservableList`.
-
-```js
-const list = new ListView({
-    list: someObservableList
-}, listValue => return new ChildView(listValue))
-```
-
-As items are added, removed, moved (change position) and updated, the DOM will be kept in sync.
-
-There is also a `LazyListView` that only renders items in and around the current viewport, with the restriction that all items in the list must be rendered with the same height.
-
-### Sub view updates
-
-Unless the `parentProvidesUpdates` option in the constructor is set to `false`, the ListView will call the `update` method on the child `IView` component when it receives an update event for one of the items in the `ObservableList`.
-
-This way, not every sub view has to have an individual listener on it's view model (a value from the observable list), and all updates go from the observable list to the list view, who then notifies the correct sub view.
