The gallery class name is used to style the element, but the latter needs to be retrieved by a JavaScript function to perform some actions. Let’s say we have defined the gallery element as such: To reinforce the concept, let’s briefly discuss an example. This is a common technique used by many developers to separate class names and JavaScript hooks.
So, if a piece of JavaScript needs to retrieve one or more elements, instead of using the existing class names, I’ll add a specific class name to the elements, prefixed with js. The class names used for styling purposes won’t be used as JavaScript hooks. Some might think that it’s overkill, but I think this is a nice opportunity to learn a new methodology you might not be familiar with. The result of our efforts is shown in the image below:Īlthough the project on its own isn’t complex, I’ll use the BEM methodology to name the classes used in addition to some helpers. The whole service will be developed paying attention to accessibility, so along the way we’ll employ the relevant role attribute where it makes sense and also ensure that it’s possible to navigate the website and trigger the various actions through the use of the TAB and ENTER keys.

However, after reading this series, you can update to code to trigger this action if you wish.) (In this project, clicking on the right arrow won’t cause the next page of thumbnails to load. We don’t want the list to become too long, so we’ll paginate the photos matched and show up to 15 photos on each page, displayed in three rows.
The gallery will also feature left and right buttons to show the previous and next images respectively.įinally, we’ll have a list of thumbnails of the photos below the gallery. The gallery will sit beneath the header and will show the image chosen in its natural size, up to a fixed width and height (we don’t want the image to overflow our layout, do we?). The header will contain the page’s title and a search form that the user can employ to find the photos matching the given text. First of all, our project will be made of a single HTML page comprising three main components: a header, a gallery, and a list of thumbnails. Before we write any code, it’s important to understand how the service will be developed.
