Initial method: Strictly CSS (less preferred)
.gallery-elements .gallery-image-big {
position: relative;
height: 230px; /* Fixed height does not maintain aspect ratio */
overflow: hidden; /* Conceals extra image height */
}
.gallery-elements .gallery-image-big img {
position: absolute; /* Centers images and preserves aspect ratio */
left: 0;
right: 0;
top: 0;
margin: auto;
display: block;
max-width: 100%;
max-height: 600px;
}
Alternative method: jQuery combined with CSS (reliable yet not flawless)
CSS: Once more, center the images using absolute positioning and hide overflow for the container div.
.gallery-elements .gallery-image-big {
position: relative;
overflow: hidden;
}
.gallery-elements .gallery-image-big img {
position: absolute;
left: 0;
right: 0;
top: 0;
bottom: 0;
display: block;
margin: auto;
max-width: 100%;
}
jQuery: Include this snippet in your script within the $(document).ready() function:
var sliderw = $('.gallery-image-big').width();
$('.gallery-image-big').css({
'height': sliderw / 1.777
});
This calculates the height based on the width - dividing by 1.777 ensures a 16:9 aspect ratio, commonly used today.
To validate code syntax, utilize . Some missing semicolons were identified. The updated demo has addressed these issues.
The reason for labeling this as "not perfect" is that the function executes only once, meaning if the window is resized, the aspect ratio will not stay consistent.
Additionally, you specified the parent div's width as 1280px and the max-width as 100%. Assuming you want it full-width unless exceeding 1280px, I have reversed these values in the demonstration.
