  • Border: It specifies the thickness of the border line around the table.

Answer 30.
1. Inside <BODY>.
Placing scripts inside the <BODY> tag, the scripts will be executed while the contents of the web page is being loaded. The web page starts displaying from the beginning of the document. When the browser sees a script code in between, it renders the script and then the rest of the web page is displayed in the browser window.

2. Inside <HEAD>.
It is a visual practice to include scripts in the head section of the web page. The main reason for this is that the body section of most of the HTM pages contains a large volume of text that specifies the contents to be displayed on the web page. Mixing a function definition also with this will create a lot of confusion for the web designer for making any kind of modification in the page. Moreover, the head section of a web page is loaded before the body section. Therefore, if any function call is made in the body section, the function will be executed as the function definition is already loaded in the memory.

3. External JavaScript file.
We can place the scripts into an external file and then link to that file from within the HTML document. This file is saved with the extension ‘.js’. Placing JavaScripts in external files has some advantages. This is useful if the same scripts is used across multiple HTML page or a whole website. It separates HTML and code which makes HTML and Java-Script easier to read and maintain. Storing JavaScript as separate files can speed up page loading.
