Programming a slideshow with HTML and CSS
It uses the approach of using animation keyframes to scroll through each of the slides by modifying each of the slide’s margin-left property during the animation. The animation type can be specified so that the slides can be animated as per the required duration and effect. We will divide the task into two sections ie., in the first, we will decorate the structure by using only HTML and in the second section, we will decorate the structure by using CSS.

Approach: For building the slideshow or carousel, we will follow the below approach.
- To display the text content on each slide, we have defined a separate div section that will carry content for each slide.
- We have the slide-wrapper class to carry all the slide frame that facilitates to apply same animation effect as well as other CSS properties to each slide.
- We have used the overflow property so that it will clip the extra content, and the rest of the content will be invisible if the content of an element is too big to fit in the specified area. The float property is used in order to align the contents to the left.
- We have used :nth-child() selector in order to apply the background color that will match the elements based on their position in a group of siblings. It matches every element that is the nth-child.
- In order to define the animation for the slideshow, the keyframes property will be used to scroll through each of the slides by modifying the margin-left property for each of the slides during the animation.
First Section: This section contains the HTML portion of the page. The slides that have to be shown are defined with their corresponding text.
Second Section: This section consists of all the styling that would be used to make the slideshow. The animation to be used to move each of the slides is defined by setting the margin-left property as required for every slide. This gives it an appearance of smoothly transitioning between each of the slides.
Complete Code: Here, we will combine the above two sections into one to achieve the mentioned task.
