The term block can have several meanings depending on the context. It may refer to:
- Block (CSS)
- A block on a webpage is an HTML element that appears on a new line, i.e. underneath the preceding element and above the following element (commonly known as a block-level element). For example,
<p>is by default a block-level element, whereas
<a>is an inline element — you can put several links next to one another in your HTML source and they will sit on the same line as one another in the rendered output.
- Block (scripting)
if (condition)block, indicating that the interpreter should run the code inside the block if the condition is true, or skip the whole block if the condition is false.
