The image poper is a popular UI component that allows every users to view the multiple images or slides in a single area, which can navigated using the various navigation option. In this process, we'll use the CSS to create the slider layout and transitions, and JavaScript to add immediate interactivity.
Before we can begin, let's make sure we have to necessary tools and files:
Text editor such as VS Code or Sublime Text
An HTML file to create the slider layout
A CSS file to style the slider
A JavaScript file to add interactivity
Images to use in the slider
Step 1: Setting up an HTML
First, let's create HTML structure for our image slider. We'll use a div element editor with a class of slider to contain the slider, and can add img elements inside it for each slide. Here's an example HTML code:
<div class="slider">
<img src="slide1.jpg" alt="Slide 1">
<img src="slide2.jpg" alt="Slide 2">
<img src="slide3.jpg" alt="Slide 3">
</div>
Note: You have to make sure to replace the image existing file names with the actual file and names and paths in your projects.
Step 2: Styling your Slider with CSS
Next, you can let's add some CSS to style our slider. We'll use CSS properties and set the width and height of the bar slider, position to the every slides, and add transitions for slide from animation. Here's the CSS code:
.slider {
width: 100%;
height: 400px;
overflow: hidden;
position: relative;
}
.slider img {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
opacity: 0;
transition: opacity 1s ease-in-out;
}
.slider img.active {
opacity: 1;
}
Let's go through each property we've used:
Width : Set width of the slider to 100% to make it more responsive.
Height : Set the every height of the slider to 400 pixels.
Overflow : Set overflow to given hidden to hide any extra images outside the slider area.
Position : Set the position of the slider to relative to make sure that the img elements inside it are positioned correctly.
Position : Set the position of the img elements to absolute to the position them on top of each other.
Top and left : Set the top and left position of the img elements to 0 to make sure that they are positioned at the top left of the slider.
Width and height : Set the width and height of the img elements to 100% to make sure if they fit inside the slider.
Opacity : Set the opacity of the img elements to 0 to make them making invisible.
Transition : Add a transition of 1 second to the opacity property to make the image fade in and out very smoothly.
.Slider img.active : Add a class of active to the currently visible for slide to make it visible.
Step 3: Adding JavaScript for Slider Interactivity
Finally, let's add some JavaScript to make our slider interactive. We'll use JavaScript to change the active class of the img elements, which will make them visible one by one. Here's the JavaScript code:
const sliderImages = document.querySelectorAll('.slider img');
let slideIndex = 0;
sliderImages[slideIndex].classList.add('active');
setInterval(() =>
