Centering a block or image. Sometimes it is not the text that needs to be centered, but the block as a whole. Or, phrased differently: we want the left and right margin to be equal. The way to do that is to set the margins to 'auto'.In case of a browser, that means the browser window). So centering an element in the viewport is very simple. Here is a complete example. (This example uses HTML5 syntax.). You can see the result in a separate document. The 'margin-right: -50%' is needed to compensate the 'left: 50%'.
Slugs and snails share many similar features. However, the most apparent difference between the two is that snails carry coiled shells on their backs whereas slugs do not contain these shells. A shell of snail is composed of calcium carbonate and it keeps growing with the growth of snail.Both produce mucous for retaining the moisture.owever, the most apparent difference between the two is that snails carry coiled shells on their backs whereas slugs do not contain these shells.

The principal differences between male and female true and false pelvis include: The female pelvis is larger and broader than the male pelvis which is taller, narrower, and more compact. The female inlet is larger and oval in shape, while the male sacral promontory projects further (i.e. the male inlet is more heart-shaped). The sides of the male pelvis converge from the inlet to the outlet, whereas the sides of the female pelvis are wider apart. The angle between the inferior pubic rami is acute (70 degrees) in men, but obtuse (90-100 degrees) in women. Accordingly, the angle is called subpubic angle in men and pubic arch in women.
