This code snippet represents a series of elements within a element (though the tag itself is missing,it’s implied).This is used for responsive images, allowing the browser to choose the most appropriate image source based on the viewport width. Let’s break down what’s happening and identify potential issues:
Understanding the Code
: Each element defines a potential image source.
srcset attribute: This is the core of the responsive image setup. It lists image URLs along with their “density descriptors” (e.g., 1x, 2x). 1x means the image is suitable for standard pixel density displays. 2x means it’s suitable for high-density (Retina) displays.
media attribute: This is a media query that specifies when the browser should use the image source defined in the srcset. It’s based on the viewport width.
tag: The final tag acts as a fallback. If the browser doesn’t support or , it will load the image specified in the src attribute of the tag. The loading="lazy" attribute tells the browser to only load the image when it’s near the viewport, improving page load performance.
Problems and Redundancies
This code is extremely redundant and inefficient. Here’s a breakdown of the issues:
- Repetitive
srcset: The first severalelements all use the samesrcset:https://www.essence.com/wp-content/uploads/2025/06/IMG5857-scaled.jpeg 1x, https://www.essence.com/wp-content/uploads/2025/06/IMG5857-scaled.jpeg 2x. this is pointless. The browser will only use the first matchingelement. The others are ignored.
- Strange
mediaQueries: Themediaqueries like(min-width: 3x1px),(min-width: 3x4px),(min-width: 4x3px),(min-width: 2x3px)are invalid and will likely be ignored by the browser. Media queries use standard units likepx,em,rem,vw,vh.3x1pxis not a valid width.min-width: nonepxis also invalid.
- Overlapping Media Queries: The later
elements withmedia="(min-width: ...px)"are more sensible, but they overlap. For example,if the viewport is 1440px wide,all of these media queries will match:
(min-width: 1440px)
(min-width: 1280px)
(min-width: 1028px)
(min-width: 768px)
(min-width: 0px)
The browser will use the first* matching ,but the order is critically important.
- Inconsistent Image Sizes: The first set of sources use the same image, while the later sources use images with
width=800andwidth=400. This suggests a desire to serve different sized images, but the initial sources defeat that purpose.
How to Fix It
Here’s a much cleaner and more effective way to write this code:
