#HTML IMAGE CAROUSEL CODE#
To achieve this, we will tackle the JavaScript code needed to get our carousel working section by section so that it’s easy to understand and follow along. We will have to add some event listeners to the next and previous control buttons so they move the slides left or right whenever they are clicked on. Our carousel isn’t working right now because we have yet to add some interactivity using JavaScript, which is exactly what we are going to do next. Inspecting the slider would show that all the slides are right there, with the last slide appearing on top, as shown below. If this wasn’t obvious already, the four slides are stacked on top of each other in the order they appear in the HTML markup because we set the position of the slides to an absolute position. But for now we need to be able to see what is going on with our slider. We’ll need this later on to hide any overflowing image. Notice we commented out an overflow property in the slider style rule above. Lastly, we will style both previous and next buttons to stay above the slides using absolute, transform, and z-index properties.This makes them all stack on top of each other within the slider container Next, we will set the slider container to have a relative position it then becomes a parent container to the slides, as we would set the position of these slides to absolute position respectively.We’ll also give the slider container and the slides a corresponding fixed width and height that is responsive We’ll start by centering the slider container in the body element using grid.
Before getting to the code, let’s take a look at what we will do : Now let’s move on to styling our carousel by creating the CSS stylesheet for it. Note: Because we are using an Unsplash random image endpoint, whenever we reload the browser we are provided with a set of new random images from Unsplash. Now that we’ve cleared that up, we’re ready to move on to the CSS part and start styling our carousel. We have chosen to go with images from Unsplash for our carousel so as not to overcomplicate our code with actual content markup. Two buttons for navigating between the slides.Four actual slides containing four random images from Unsplash, respectively.To keep things simple, we will need just a few HTML elements: We’ll start by creating the HTML markup structure of the carousel. With that said, let’s get started! Creating the HTML markup for the carousel It can also lead to code conflicts between the library or plugin and our existing application codebase, which can take time to get fixed.īuilding your own carousel with just HTML, CSS, and vanilla JavaScript can be the most effective solution because it would take less time to implement with no added dependency, nor will it give rise to conflicts/errors. This might lead to extra load time because these dependencies have to be downloaded. While this is reasonable and perfectly fine, using external libraries and such often adds unnecessary dependencies and code bloatware to our application. Often when there is a need to implement a carousel within a website based on design requirements or just for aesthetic reasons, we immediately consider using an existing library, plugin, or something already prebuilt to save time. Potential problems with prebuilt carousel components In this tutorial, we will take a look at how we can build a carousel with just HTML, CSS, and plain old vanilla JavaScript. Whether it’s for rendering a slideshow, a testimonials section, or showcasing multiple messages in a slider, carousels are indispensable. When you are limited in space but still want to display a lot of information, carousels come in very handy as they are perfect for displaying groups of related or unrelated content. There is no doubt that carousels are essential components in a website’s design.
