I have been wanting to gain more control over my images on various screen sizes for quite some time now. Recently, I discovered the <picture> tag in HTML5.
Currently, I am using Bootstrap 3. However, I'm not sure if it is effective to combine Bootstrap and the <picture> tag. So far, I haven't noticed any significant changes in the test code I created.
