When iOS updates include new emojis, the image — of a question mark in a box — stands in for a new emoticon you don’t have access to. It means your friend is using an emoji that’s only available in a newer software version. If you have an Android, this placeholder character will show up as an empty rectangle, according to Emojipedia. People who take forever to update their phones are likely familiar with it. how the box of an element is sized and aligned, which is primarily controlled by the display property (and width, height and margin). So, an x-height is literally the height of an x character in the font rather than half the height of the parent element. At the core, CSS layout is about mapping a set of HTML elements to a set of rectangular boxes that can be positioned on the x-, y- and z-axis. Let's go through the specifics of each of these behaviors along with a couple of illustrative code examples.In short, the reason why this centering technique works is because we have forced the line height of the container to be 100% percent of the parent height, and then have asked for the centered item to be positioned at the midpoint of the sibling (green) element. Assuming that the box to be centered is less wide than the container, all of this will be placed on a single, very tall line box and the end result is vertical and horizontal centering.
