Hi Anant,
That’s a WP Image Block. It’s set to float right which is causing the issue.
Try adding this through Appearance > Customize > Additional CSS:
@media (max-width: 768px){
.wp-block-image figure.alignright, .wp-block-image figure.alignright img {
width: 100%;
float:unset;
margin-left: unset;
}
}
Alternatively, you can use a GenerateBlocks Image Block instead. With this, you can set different alignments for different views through the settings.
