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

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.

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>
