```
$(document).ready(function () {
    $('p').append('This is a paragraph'); // appending text to all p elements
});
```
The code above will execute:


<pre><code>$(document).ready(function () {
    $('p').append('This is a paragraph'); // appending text to all p elements
});
</code></pre>
<p>The code above will execute:</p>


```html
 <body>
   <div id = 30>
   </div>
   <div>
     <p>
     </p>
   <div>
     <p id = 20>
     </p>
 </body>
```
For the HTML page above, the jQuery selector to return the element with an `id` of `20` will be:

<pre><code class="language-html"> &lt;body&gt;
   &lt;div id = 30&gt;
   &lt;/div&gt;
   &lt;div&gt;
     &lt;p&gt;

   &lt;div&gt;
     &lt;p id = 20&gt;
     &lt;/p&gt;
 &lt;/body&gt;
</code></pre>
<p>For the HTML page above, the jQuery selector to return the element with an <code>id</code> of <code>20</code> will be:</p>


```html

   <div>
     <p>
     </p>
   <div>

For the HTML page above, the jQuery selector to return all the elements with `class` of `italicText` will be:

<pre><code class="language-html"> &lt;body&gt;
   &lt;div class='italicText'&gt;
   &lt;/div&gt;
