# <text> Development


The <text> component is used to display a piece of textual information. For details, see [text](../reference/arkui-js/js-components-basic-text.md).


## Creating a <text> Component

Create a <text> component in the .hml file under pages/index.


```
<!-- xxx.hml -->
<div class="container" style="text-align: center;justify-content: center; align-items: center;">
  <text>Hello World</text>
</div>
```


```
/* xxx.css */
.container {
  width: 100%;
  height: 100%;
  flex-direction: column;
  align-items: center;
  justify-content: center;
  background-color: #F1F3F5;
}
```

## Setting the Text Style and Attributes

- Adding a text style


  Set the color, font-size, allow-scale, word-spacing, and text-valign attributes to apply the color, size, zoom, spacing, and vertical alignment styles to the text.

  ```
  <!-- xxx.hml -->
  <div class="container" style="background-color:#F1F3F5;flex-direction: column;justify-content: center; align-items: center;">   
    <text style="color: blueviolet; font-size: 40px; allow-scale:true"> 
      This is a passage
    </text>
    <text style="color: blueviolet; font-size: 40px; margin-top: 20px; allow-scale:true;word-spacing: 20px;" >
      This is a passage
    </text>
  </div>
  ```

  

  ```
  /* xxx.css */
  .container {
    width: 100%;
    height: 100%;
    flex-direction: column;
    align-items: center;
    justify-content: center;
    background-color: #F1F3F5;
  }
  ```

- Adding a text modifier


  Set the text-decoration attribute to add a line to selected text. Set the text-decoration-color attribute to apply specific color to the added line. For values of text-decoration, see [Text Style](../reference/arkui-js/js-components-basic-text.md).

  ```
  <!-- xxx.hml -->
  <div class="container" style="background-color:#F1F3F5;">
    <text style="text-decoration:underline">
      This is a passage
    </text>
    <text style="text-decoration:line-through;text-decoration-color: red">
      This is a passage
    </text>
  </div>
  ```

  ```
  /* xxx.css */
  .container {
    width: 100%;
    height: 100%;
    flex-direction: column;
    align-items: center;
    justify-content: center;
  }
  text{
    font-size: 50px;
  }
  ```

- Hiding text content


  Set the text-overflow attribute to ellipsis so that overflowed text is displayed as an ellipsis.

  ```
  <!-- xxx.hml -->
  <div class="container">
    <text class="text">
      This is a passage
    </text>
  </div>
  ```

  ```
  /* xxx.css */
  .container {
    width: 100%;
    height: 100%;
    flex-direction: column;
    align-items: center;
    background-color: #F1F3F5;
    justify-content: center;
  }
  .text{
    width: 200px;
    max-lines: 1;
    text-overflow:ellipsis;
  }
  ```


  > ![icon-note.gif](public_sys-resources/icon-note.gif) **NOTE**:
  > - text-overflow must be used together with max-lines.
  >
  > - max-lines indicates the maximum number of lines in the text.

- Setting the text line breaking mode


  Set the word-break attribute to specify how to break lines of text. For values of word-break, see [Text Styles](../reference/arkui-js/js-components-basic-text.md).

  ```
  <!-- xxx.hml -->
  <div class="container">
    <div class="content">
      <text class="text1">
        Welcome to the world
      </text>
      <text class="text2">
        Welcome to the world
      </text>
    </div>
  </div>
  ```

  ```
  /* xxx.css */
  .container {
    background-color: #F1F3F5;
    flex-direction: column;
    align-items: center;
    justify-content: center;
  }
  .content{
    width: 50%;
    flex-direction: column;
    align-items: center;
    justify-content: center;
  }
  .text1{
    height: 200px;
    border:1px solid #1a1919;
    margin-bottom: 50px;
    text-align: center;
    word-break: break-word;
    font-size: 40px;
  }
  .text2{
    height: 200px;
    border:1px solid #0931e8;
    text-align: center;
    word-break: break-all;
    font-size: 40px;
  }
  ```

- Setting the [&lt;span&gt;](../reference/arkui-js/js-components-basic-span.md)child component

```
<!-- xxx.hml -->
<div class="container" style="justify-content: center; align-items: center;flex-direction: column;background-color: #F1F3F5;">
  <text style="font-size: 45px;">
    This is a passage
  </text>
  <text style="font-size: 45px;">
    <span style="color: aqua;">This </span><span style="color: #F1F3F5;">      1    </span>    <span style="color: blue;"> is a </span>    <span style="color: #F1F3F5;">      1    </span>    <span style="color: red;">  passage </span>
  </text>
</div>
```

> ![icon-note.gif](public_sys-resources/icon-note.gif) **NOTE**:
> - When the &lt;span&gt; child component is used to form a text paragraph, incorrect &lt;span&gt; attribute settings (for example, setting of font-weight to 1000) will result in abnormal display of the text paragraph.
> 
> - When the &lt;span&gt; child component is being used, do not include any text you want to show in the &lt;text&gt; component, as such text will not be displayed if you do so.


## Example Scenario

Use the &lt;text&gt; component to display text content through data binding. Use the &lt;span&gt; child component to hide or display text content by setting the show attribute.


    ```
    <!-- xxx.hml -->
    <div class="container">
      <div style="align-items: center;justify-content: center;">
        <text class="title">
          {{ content }}
        </text>
        <switch checked="true" onchange="test"></switch>
      </div>
      <text class="span-container" style="color: #ff00ff;">
        <span show="{{isShow}}">  {{ content  }}  </span>
        <span style="color: white;">
            1
        </span>
        <span style="color: #f76160">Hide clip </span>
      </text>
    </div>
    ```


```
/* xxx.css */
.container {
  align-items: center;
  flex-direction: column;
  justify-content: center;
  background-color: #F1F3F5;
}
.title {
  font-size: 26px;
  text-align:center;
  width: 200px;
  height: 200px;
}
```


```
// xxx.js
export default {   
  data: {    
    isShow:true,    
    content: 'Hello World'
  },   
  onInit(){    },  
  test(e) {    
    this.isShow = e.checked  
  }
}
```
