HTML/CSS, JavaScript with jQuery, and Bootstrap Online Test

Every user on your website has an image avatar that is displayed when they post a comment. You want to style these images differently from other images on your site. Add a CSS class named avatar that fulfils the following requirements:

1. The avatar's border is rounded, so that it appears as a circle.
2. The avatar's width and height are both 150px.
3. The avatar has a solid border, has a width of 2px, and be colored gray.

For example, the avatar in the template should look like:

An image gallery is a set of images with corresponding remove buttons. This is the HTML code for a gallery with two images:

<div class="image">
  <img src="https://goo.gl/kjzfbE" alt="First">
  <button class="remove">X</button>
</div>
<div class="image">
  <img src="https://goo.gl/d2JncW" alt="Second">
  <button class="remove">X</button>
</div>

Implement the setup function that registers a click event handler and implements the following logic: When the button of class remove is clicked, its parent <div> element should be removed from the gallery.

For example, after the first image has been removed from the gallery above, it's HTML code should look like this:

<div class="image">
  <img src="https://goo.gl/d2JncW" alt="Second">
  <button class="remove">X</button>
</div>

The HTML page contains a button and modal dialog.

Using just Bootstrap's HTML attributes and no JavaScript, add attributes to the elements so that:

1. When the Open button is clicked, the modal dialog is opened.
2. When the Close button is clicked, the modal dialog is closed.
