Your question is not clear enough. The height and width attributes are added dynamically for responsive design. That is why some images may be used without the attributes and their height and width are configured by CSS.
Yes, these images are smaller or bigger depending on the width of the screen. If this image would have the attribute it would be cut or blur that is why they do not have width and height inline and their height and width are configured by the height and width of the parent block.
Hi and thanks for the clarity and logical reasoning.The question was raise based on a website performance report as we continue work on our optimizing tactics.
Although compulsory, always including the ‘width/height’ attributes in the source of images is a best practice in web design, This data is also favorable with search engine indexing and overall website performance benchmarks. The ‘width/height’ attributes supports proper solid frontend design.
