We usually use text-align CSS property on the container to set the alignment of the child elements. So in case of <img> tag we can take help of a block container element e.g div or span(the span must have display:block as its style) in the following way:
<div style="text-align:center"> <img src="1.jpg"> </div>
But the code seems redundant because we need only to center the image and for that we need a container!!!
There is a way out…
You can simply use 2 CSS attributes i.e display and margin. Below there is the syntax:
<img src="1.jpg" style="display:block; margin:auto;">
