With SVG we can add a clipping path to change the shape of our images. First we open a SVG tag with namespaced href attribute and namespace definition: <svg class=svg-graphic width=180 height=200 viewBox=0 0 560 645 xmlns=http://www.w3.org/2000/svg xlink=http://www.w3.org/1999/xlink version=1.1>.

The most common migraine triggers include: Food. Salty foods or aged foods, such as cheese and salami, may cause migraine headaches. Highly processed foods can trigger a migraine, too.
