Reducing cumulative layout shift for responsive images - core web vitals

[seoelevated]

In preparation for Core Web Vitals becoming a ranking factor in May 2021, we are making efforts to reduce our Cumulative Layout Shift (CLS) on pages where the shift is being caused by images loading. The general recommendation is to specify both height and width attributes in the html, in addition to the CSS formatting which is applied when the images load. However, this is problematic in situations where responsive images are being used with different aspect ratios for mobile vs desktop. And where a CMS is being used to manage the pages with images, where width and height may change each time new images are used, as well as aspect ratios for the mobile and desktop versions of those.

So, I'm posting this inquiry here to see what kinds of approaches others are taking to reduce CLS in these situations (where responsive images are used, with differing aspect ratios for desktop and mobile, and where a CMS allows the business users to utilize any dimension of images they desire).

Hi,
I am facing issue of higher cumulative layout shift. The reason behind this is that I am loading css script at the end once complete page is rendered (in order to reduce page loading time. So page loading time is reduced on the cost of higher cumulative layout shift. I am new in SEO. Kindly suggest me, for improved google search ranking, whether it will matter and whether I should load css at the start itself for reducing cumulative layout shift. Also, being a pin code finder website, texts are limited only. Should I add more text in webpages for improved ranking. (for reference, the website is https://pincodeinfo.online )

I'm in the same exact situation as well!  Feels like we are kind of stuck as I also have different aspect ratios for device and use a CMS  that has a lot of limitations.
