Adjustable picture sizes

Question

Adjustable picture sizes

There's an issue I'm experiencing where images take a moment to load when the page loads. This not only affects the appearance but also interferes with the functionality of a scroll-up button that needs to be positioned at the bottom of the page once scrolled down - however, since the images don't occupy any space on page load, the JS calculates the page length incorrectly. Typically, you would set height and width directly on the image, but in this case, image dimensions change based on screen width (as seen in the mobile example above where the image is fluid). Therefore, setting a fixed width/height based on breakpoints isn't feasible.

Is there a solution available to dynamically adjust the image height based on its width?

To clarify why I need to absolutely position my scroll button:

Answer №1

It appears that all of your images have the same aspect ratio, so why not just set the width and let the height adjust automatically?

This will allow the image to scale properly based on its original proportions.

The issue with the JavaScript calculation seems to be more related to timing than CSS. It is possible that the calculation function is being triggered too early.

Additionally,

The positioned button does not necessarily need a calculated position... Instead of setting a calculated "top" value, consider using a fixed "bottom" value based on your requirements. You may also want to hide the button until a certain scroll point is reached to ensure it is not visible upon initial load or before loading maximum items.

// EDIT: If necessary, consider using "setTimeout" as a last resort after exploring other layout and positioning solutions. Using timeouts can complicate things and make them less reliable, so exhaust other options first.

For faster browser rendering, it is important to be specific about image sizes. When the browser doesn't know the size of an image, it will first render all text and then wait for images to load before adjusting the layout around them. This can cause delays in displaying content.

To ensure responsive images, you can add the following code to your CSS file:

img {
    width: 100%;
    height: auto;
    display: block;
}

If you have missing images that are disrupting your layout, you can use a simple JavaScript solution:

<img src="imagenotfound.gif" alt="Image not found" onerror="this.onerror=null; this.src='imagefound.gif';" />
