Make your website load faster in Divi Theme using image srcsets.
<h3>The Problem – Images on divi webpage serving single image size irrespective of devices sizes</h3>
<ul>
<li>Is your divi webpage slow?</li>
<li>Do the tags serve a single size irrespective of the device size?</li>
</ul>
<blockquote>
<a href="https://neilpatel.com/blog/speed-is-a-killer/" rel="nofollow ugc">A slower website causes decrease in sales due to increase in bounce rate.</a>
</blockquote>
A responsive image offers different sizes of the same image. The browser decides the best image size to render.
Divi includes a fullsize and regular image module. They don’t serve a responsive image. It’s a one-size-fits-all.
The non-responsive image have a single image size. The same image loads on large desktop, tablet and mobiles.
<blockquote>
Let’s say you use the native divi image module with image of size 2000px. Serving the 2000px wide image on a device with width 400px serves no purpose other than to slow down the webpage.
</blockquote>
<h3>The Solution – Divi responsive image size plugin</h3>
The <a href="https://wptools.app/wordpress-plugin/divi-responsive-image-sizes-plugin/" rel="nofollow ugc">Divi Responsive Image Size</a> plugin has two modules.
<ul>
<li>Responsive Image divi module – It’s available in regular divi section.</li>
<li>Fullwidth Responsive Image divi module – It’s available in fullwidth divi section.</li>
</ul>
<blockquote>
Both the modules help creates a image tag with responsive image sizes.
</blockquote>
A responsive image adds the srcset and sizes attributes to the image markup.
<h3>What does srcset and sizes do?</h3>
Consider the example of an <img> tag
<blockquote>
<img alt="Divi responsive image sizes" src="default.jpg" srcset="small.jpg 240w, medium.jpg 300w, large.jpg 720w" sizes="(max-width: 360px) 300px, 100vw">
</blockquote>
Let’s go over each attribute.
<blockquote>
alt=”Divi responsive image sizes”`
</blockquote>
The <code>alt</code> attribute describes the alternative text for the image. Browser loads this text when it can’t find the image.
<blockquote>
src=”default.jpg”
</blockquote>
The <code>src</code> attribute defines a fallback image path for browsers that don’t support srcset and sizesattributes
<blockquote>
srcset=”small.jpg 240w, medium.jpg 300w, large.jpg 720w”
</blockquote>
The <code>srcset</code> attribute lists images at different sizes. Along with each image path we specify it’s width in pixels.
<blockquote>
sizes=”(max-width: 360px) 300px, 100vw”
</blockquote>
The sizes attribute instructs the browser on how to pick the right image from the srcset based on the viewport (device) size.
Going by the above example,
<ul>
<li>For viewport size 360px and below, browser displays medium.jpg (300px) image.</li>
<li>For viewport size above 360px, browser displays large.jpg image that is 720px wide.</li>
</ul>
<h3>Divi image sizes</h3>
Divi supports following css media breakpoints.
<ul>
<li>Large screens (1405px upwards)</li>
<li>Laptops and desktops (between 1100px and 1405px)</li>
<li>Tablets in landscape mode (between 981px and 1100px)</li>
<li>Tablets in portrait mode (between 768px and 980px)</li>
<li>Smart phones in landscape mode (between 480px and 768px)</li>
<li>Smart phones in portrait mode (between 0 and 479px)</li>
</ul>
For every breakpoint, the responsive divi modules has a corresponding field to set the image width.
<h3>Improve image SEO score</h3>
Image SEO is important. The responsive divi modules follows <a href="https://developers.google.com/style/images" rel="nofollow ugc">google recommendations for image SEO</a>
