###### tags: `HTML, CSS`

**The HTML <script> Tag**
The HTML <script> tag is used to **define a client-side script (JavaScript)**.

The <script> element either contains script statements, **or it points to an external script file through the src attribute.**

Common uses for JavaScript are image manipulation, form validation, and dynamic changes of content.

第一種方法是直接寫入JAVASCRIPT進去SCRIPT裡面
