About the Extension

Google Pagespeed Insights outputs the message "Image elements do not have explicit width and height" for Shopware shops that are based on the responsive theme.


The reason is that the logo is displayed without the HTML attributes width and height. Then it is scaled using CSS max-width and max-height so that it adapts to the screen size.

In order to decide how big the logo should actually be displayed, the browser must first download the file and then scale it based on the height of the header.

During this process, a so-called layout shift can occur in which the logo is initially displayed larger and then subsequently reduced. The result is a poorer rating on the Cumulative Layout Shift parameter.

With our plugin you can add these HTML attributes. Simply enter the width and height in the plugin settings with which your logo will be displayed on common mobile devices. This allows the browser to reserve space for the logo before the file itself has been loaded and the CSS has been parsed.
