I'm struggling to create a vertical center-aligned image gallery on my website with "PREVIOUS" and "NEXT" links for easy navigation. Despite multiple attempts, I can't seem to get it right. Can someone guide me on how to achieve this effect?
Check out this easy method:
HTML
<div>
<span>before</span>
<img src="https://www.example.com/images/logo.png">
<span>after</span>
</div>
CSS
div span,
div img {
display: inline-block;
vertical-align: middle;
}
This technique is effective because it allows you to adjust the vertical-align property for inline-block elements. Unlike regular inline elements, which are always aligned to the text baseline, giving you more control over alignment on your website.
Why isn't the simple solution working appropriately?
<div class="myGallery">
<span>before</span>
<img src="http://www.spiraluniverse.com/uploads/tx_templavoila/image1.jpg">
<span>after</span>
</div>
CSS
.myGallery img {
vertical-align: middle;
}

To create functionality for navigating between images using previous and next links, you can implement the following CSS:
.image-gallery {
position: relative;
}
.next { right: 0; }
.prev { left: 0; }
.next, .prev {
position: absolute;
top: 50%;
}
The .next and .prev elements are absolutely positioned within their parent (.image-gallery) with a vertical offset based on their height percentage. For example, if an element is 10% in height, the top value would be set to 45%. Adjustments may be needed for the left and right properties to align with the width of the elements accurately.
This method offers flexibility and is compatible with most web browsers.
Sample HTML implementation:
<div class="image-gallery">
<a class="prev" href="#">Previous</a>
<img src="..." />
<a class="next" href="#">Next</a>
</div>
Remember that the vertical-align property does not apply to block-level elements according to W3C standards.
In this situation, it is recommended to utilize absolute positioning in relation to the gallery container. Once this is set up, use margins to fine-tune the position of the buttons. This method ensures that the buttons stay in place even if the container div expands vertically, such as when accommodating a taller image.
.gallery {
/*our container element*/
position:relative;
}
.btn-prev, .btn-next {
width:40px;
height:40px;
margin:-20px 0;
position:absolute;
top:50%;
}
.btn-prev {
/*remember to correctly position the buttons horizontally*/
left:0;
}
.btn-next {
right:0;
}
