Display a carousel image in the center with previous and next sliders for easy navigation

Currently, I am referencing this tutorial

My goal is to make the image smaller and centered on the page

I have made adjustments to the CSS to decrease the size:

min-height: 350px;
max-width: 900px;

However, the image is still aligned to the left and the slider icons are stuck on the left and right sides. Can anyone provide any suggestions or guidance on how to resolve this issue?

Answer №1

If I'm not mistaken, it seems like you're looking to resize an image and center it. Here's an example of how you can achieve this using CSS:

#carouselExampleIndicators{
margin: auto;
min-height: 350px;
max-width: 900px;
overflow: hidden;
}

.carousel-item {
  height: 65vh;
  min-height: 350px;
  background: no-repeat center center scroll;
  -webkit-background-size: cover;
  -moz-background-size: cover;
  -o-background-size: cover;
  background-size: cover;
}

Answer №2

To customize the width of an image within a carousel without affecting the carousel's overall dimensions, consider using the <img> tag to insert images and then style them accordingly.

.carousel-item {
  height: 65vh;
  min-height: 350px;
  background: no-repeat center center scroll;
}

.carousel-item>img{
  max-width:900px;
  height:100%;
  margin:auto;
  display:block;
}
