pseudo_elements.md

Styling native elements
-------------
Native HTML controls are a challenge to style. You can style any element in the web platform that uses Shadow DOM with a pseudo element `::pseudo-element` or the `/deep/` path selector.

```css
video::webkit-media-controls-timeline {
  background-color: lime;
}

video /deep/ input[type=range] {
  background-color: lime;
}
```

Note
-------------
All Trident pseudo-elements listed here were added in IE10 and will not work in earlier versions of Internet Explorer. In WebKit, to style some pseudo-elements you must set the basis element’s `-webkit-appearance` pseudo-class to `none`.


&lt;input type="search"&gt;
-------------

```css
input[type=search]::-webkit-search-cancel-button

input[type=search]::-webkit-search-cancel-button:after

input[type=search]::-webkit-search-decoration

input[type=search]::-webkit-search-results-decoration

input[type=search]::-webkit-search-results-button

input[type=search]::-webkit-textfield-decoration-container
```


&lt;input type="file"&gt;
-------------
WebKit provides a hook for its file input button with the pseudo-element.

```css
input[type=file]::-ms-browse

input[type=file]::-webkit-file-upload-button

input[type=file]:focus::-webkit-file-upload-button

input[type=file]:active::-webkit-file-upload-button

input[type=file]:active:disabled::-webkit-file-upload-button

input[type=file] > input[type=button]::-moz-focus-inner
```

&lt;input type="range"&gt;
-------------
WebKit provides a pseudo-element for the track and for the range handle itself. As of Firefox 22, Gecko provides pseudo-elements for styling range inputs. Trident provides a bunch of pseudo-elements to customize its range selector.

```css
input[type=range]::-webkit-slider-container

input[type=range]::-webkit-media-slider-container

input[type=range]::-webkit-slider-runnable-track

input[type=range]:focus::-webkit-slider-runnable-track

input[type=range]::-webkit-slider-thumb

input[type=range]::-webkit-slider-thumb:before

input[type=range]::-webkit-slider-thumb:after

input[type=range]:active::-webkit-slider-thumb

input[type=range]:hover::-webkit-slider-thumb:before

input[type=range]:hover::-webkit-slider-thumb:after

input[type=range]:focus::-webkit-slider-thumb:before

input[type=range]:focus::-webkit-slider-thumb:after

input[type=range]:disabled::-webkit-slider-thumb:before

input[type=range]:disabled::-webkit-slider-thumb:after

input[type=range]::-webkit-media-slider-thumb

input[type=range]:disabled::-webkit-slider-thumb

input[type=range]:hover::-webkit-slider-thumb

input[type=range]:focus::-webkit-slider-thumb

input[type=range]::-webkit-color-swatch-wrapper

input[type=range]::-webkit-color-swatch

input[type=range]::-moz-range-track

input[type=range][orient=vertical]::-moz-range-track

input[type=range]:focus::-moz-range-track

input[type=range]::-moz-range-progress

input[type=range]::-moz-range-thumb

input[type=range]:focus::-moz-range-thumb

input[type=range]:focus::-moz-range-thumb:before

input[type=range]:focus::-moz-range-thumb:after

input[type=range]::-moz-focus-outer

input[type=range]::-ms-fill-lower

input[type=range]::-ms-fill-upper

input[type=range]::-ms-ticks-before

input[type=range]::-ms-ticks-after

input[type=range]::-ms-thumb

input[type=range]::-ms-thumb:hover

input[type=range]::-ms-track

input[type=range]:focus::-ms-track

input[type=range]::ms-tooltip
```


&lt;input type="time"&gt;
-------------
Applies one or more styles to the clear button of a text input control. The clear button is shown only when the text input control has focus and is not empty.

```css
input[type=time]::-ms-clear

input[type=time]::-webkit-clear-button
```


&lt;input type="date"&gt;
-------------
The following pseudo-elements are made available by WebKit for customizing a date input’s textbox.

```css
input[type=date]::-webkit-datetime-edit

input[type=date]::-webkit-datetime-edit-fields-wrapper

input[type=date]::-webkit-datetime-edit-text

input[type=date]::-webkit-datetime-edit-month-field

input[type=date]::-webkit-datetime-edit-year-field

input[type=date]::-webkit-inner-spin-button

input[type=date]::-webkit-calendar-picker-indicator

input[type=date]::-webkit-clear-button
```


&lt;input type="color"&gt;
-------------
Webkit provides two pseudo elements for its color picker.

```css
input[type=color]::-webkit-color-swatch

input[type=color]::-webkit-color-swatch-wrapper

input[type=color]::-moz-color-swatch

input[type=color]::-moz-focus-inner
```


&lt;input type="number"&gt;
-------------
WebKit provides a spinner control by default for number picker inputs. While you cannot do a whole lot with these elements, it can be useful to hide the spinner.

```css
input[type=number]::-webkit-textfield-decoration-container

input[type=number]::-webkit-textfield-decoration-container:before

input[type=number]::-webkit-textfield-decoration-container:after

input[type=number]::-webkit-inner-spin-button

input[type=number]::-webkit-outer-spin-button

input[type=number]::-moz-number-wrapper

input[type=number]::-moz-number-text

input[type=number]::-moz-number-spin-box

input[type=number]::-moz-number-spin-up

input[type=number]::-moz-number-spin-down
```


&lt;input type="checkbox"&gt;
-------------
Trident provides a pseudo-element for checkbox button control.

```css
input[type=checkbox]::-ms-check
```


&lt;input type="radio"&gt;
-------------
Trident provides a pseudo-element for the radio button control.

```css
input[type=radio]::-ms-check
```


&lt;input type="text"&gt;
-------------
As of IE10 Trident provides the pseudo-element ::-ms-value to style the value portion of text inputs. Further more in IE10 when a text input has focus and is not empty, a small (x) control appears in the right hand side of the input. When clicked, the control will clear the contents of the text input.

```css
input[type=text]::-ms-value

input[type=text]::-ms-clear
```


&lt;input type="password"&gt;
-------------
Trident provides a control on password inputs that can be pressed to display the password in plain text. And as of IE10 Trident provides the pseudo-element ::-ms-value to style the value portion of text inputs.

```css
input[type=password]::-ms-reveal

input[type=password]::-ms-value
```


&lt;input type="reset"&gt;
-------------

```css
input[type=reset]::-moz-focus-inner
```


&lt;input type="submit"&gt;
-------------

```css
input[type=submit]::-moz-focus-inner
```


&lt;input type="button"&gt;
-------------

```css
input[type=button]::-moz-focus-inner
```


placeholder Attribute
-------------
WebKit and Gecko provide a placeholder pseudo-element. *Note: Gecko switched from the pseudo-class `:-moz-placeholder` to the pseudo-element `::-moz-placeholder` in Firefox 19.*

```css
::-moz-placeholder

:-ms-input-placeholder

::-webkit-input-placeholder
```


&lt;keygen&gt;
-------------
WebKit provides a pseudo-element that can be used to customize the dropdown that a keygen element uses.

```css
::-webkit-keygen-select
```


&lt;input&gt;
-------------
Gecko and Webkit applies following pseudo-elements to there inputs.

```css
input:valid + label::after

input:invalid + label::after

input::-webkit-input-list-button

input::-webkit-input-speech-button

input::-webkit-textfield-decoration-container

input::-webkit-calendar-picker-indicator

input::-moz-placeholder

input::-moz-focus-inner

input::-ms-clear
```


&lt;button&gt;
-------------

```css
button::-moz-focus-inner
```


&lt;select&gt;
-------------
As of IE10 Trident gives you a hook to style the arrow within select dropdowns.

```css
select::-ms-expand
```


&lt;details&gt;
-------------

```css
details::-webkit-details-marker
```


&lt;summary&gt;
-------------

```css
summary::-webkit-details-marker
```


&lt;meter&gt;
-------------
WebKit provides pseudo-elements to customize the display of meter elements. 

```css
meter::-webkit-meter

meter::-webkit-meter-horizontal-bar

meter::-webkit-meter-vertical-bar

meter::-webkit-meter-horizontal-optimum-value

meter::-webkit-meter-horizontal-suboptimal-value

meter::-webkit-meter-horizontal-even-less-good-value

meter::-webkit-meter-vertical-optimum-value

meter::-webkit-meter-vertical-suboptimal-value

meter::-webkit-meter-vertical-even-less-good-value

meter::-moz-meter-bar

meter:-moz-meter-optimum::-moz-meter-bar

meter:-moz-meter-sub-optimum::-moz-meter-bar

meter:-moz-meter-sub-sub-optimum::-moz-meter-bar
```

On Mac OS X, WebKit provides multiple built-in appearances for `<meter>`.
```css
 /* Default */
-webkit-appearance: continuous-capacity-level-indicator;
-webkit-appearance: discrete-capacity-level-indicator;
-webkit-appearance: relevancy-level-indicator;
-webkit-appearance: rating-level-indicator;
```


&lt;progress&gt;
-------------
WebKit provides pseudo-elements to style progress elements. And Gecko provides a pseudo-element to style the progress bar itself. Like Gecko, Trident provides a single pseudo-element to style the progress bar.

```css
progress::-webkit-progress-bar

progress::-webkit-progress-value

progress::-webkit-progress-bar-value

progress::-moz-progress-bar

progress::-ms-fill
```


&lt;textarea&gt;
-------------
This pseudo-element also allows some basic styling for the textarea resizer.

```css
textarea::-webkit-resizer

textarea::-webkit-resizer:window-inactive

textarea::-webkit-input-placeholder

textarea::-moz-placeholder
```

*Note: Adding `display: none` to `::-webkit-resizer` doesn't actually prevent the user from resizing the textarea, it just hides the control. If you want to disable resizing in textarea use this.*

```css
textarea {
  resize: none;
}
```


&lt;img&gt;
-------------
```css
img::-webkit-image-inner-element
```


&lt;p&gt;
-------------

```css
p::after

p::before

p::first-letter

p::first-line

p::selection
```


&lt;video&gt;
-------------

```css

markdown 每日笔记

space in filenmae.md

Markdown don't allow space in the filenames. So encode to `%20` to replace the space in the filenames.

e.g. 

`([ontology](2.1 Ontologies.md))`

should be

`([ontology](2.1%20Ontologies.md))`

internal hyperlink.md

For example, you have a repo like the following:

``` html
project/
    text.md
    subpro/
       subtext.md
       subsubpro/
           subsubtext.md
       subsubpro2/
           subsubtext2.md
```
* The relative link to `subtext.md` in `text.md` might look like this:

`[this subtext](subpro/subtext.md)`
* The relative link to `subsubtext.md` in `text.md` might look like this:

`[this subsubtext](subpro/subsubpro/subsubtext.md)`
* The relative link to `subtext.md` in `subsubtext.md` might look like this:

`[this subtext](../subtext.md)`
* The relative link to `subsubtext2.md` in `subsubtext.md` might look like this:

`[this subsubtext2](../subsubpro2/subsubtext2.md)`
* The relative link to text.md in subsubtext.md might look like this:

`[this text](../../text.md)`

markdown Pasarparámetrosdesde纸质按钮

Códigoparapasarparámetrosonunmétodosdesdeun componente，por ejemplo paper-button。 <br/>

pass-param.md

## Pasar parámetros

Antes de nada debemos definir el componente, en este caso un paper-button.

```html
<paper-button class="buton-edit">Edit</paper-button>
```

Después deberemos definir el método que enlazaremos como manejador de algun evento de nuestro componente.

```javascript
_handleEdit(e){
    console.log('Button click event launched');
  }
```

Ahora agregaremos el evento al componente utilizando el siguiente código `on-click="_handleEdit"`

```html
<paper-button class="buton-edit" on-click="_handleEdit">Edit</paper-button>
```

En seguida agregamos una propiedad para agregar los parámetros a nuestra función con el siguiente código `data-args="value 1"`

```html
<paper-button class="buton-edit" on-click="_handleEdit" data-args="value 1">Edit</paper-button>
```

__Nota:__ para agregar un parámetro a manera de variable es necesario agregar un `$` antes de la asignación del `data-args`


```html
<paper-button class="buton-edit" on-click="_handleEdit" data-args$="[[item.name]]">Edit</paper-button>
```

Un ejemplo de como obtener el argumento pasado se describe en el siguiente código

```javascript
_handleEdit(e){
    console.log('Args');
    let uid = e.target.getAttribute('data-args'); // Obtener parámetros
    window.history.pushState({}, null, '/service/'.concat(uid)); // navegar hacia otra página
    window.dispatchEvent(new CustomEvent('location-changed')); // Notificar que queremos navegar
  }
```
