                            **border-left**

* 描述：復合屬性。設置對象左邊框屬性。
* 版本：CSS1
* 繼承性：無	

**語法**
```
border-left: border-left-width | border-left-style | border-left-color;
```

顏色種類

* border-left-width：設置邊框的寬度。
* border-left-style：設置邊框的樣式。
* border-left-color：設置邊框的顏色。
* inherit：設置從父元素繼承 border 的屬性。


**使用說明**

雖然有三個參數可以設置，并不強制全部設置。如：border-left:solid #ff0000;
若使用該復合屬性定義其單個參數，則其他參數的默認值將無條件覆蓋各自對應的單個屬性設置。

**代碼示例**

```
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>border-left</title>
    <style>
        #container{
            width: 50px;
            height: 50px;
            border-style:solid;
            border-left:thick double #ff0000;
