HTML
<p>
element
表示段落。
Paragraphs are usually represented in visual media as blocks of text separated from adjacent blocks by blank lines and/or first-line indentation, but HTML paragraphs can be any structural grouping of related content, such as images or form fields.
Paragraphs are
块级元素
, and notably will automatically close if another block-level element is parsed before the closing
</p>
tag. See “Tag omission” below.

By default, browsers separate paragraphs with a single blank line. Alternate separation methods, such as first-line indentation, can be achieved with CSS :
<p>Separating paragraphs with blank lines is easiest for readers to scan, but they can also be separated by indenting their first lines. This is often used to take up less space, such as to save paper in print.</p> <p>Writing that is intended to be edited, such as school papers and rough drafts, uses both blank lines and indentation for separation. In finished works, combining both is considered redundant and amateurish.</p> <p>In very old writing, paragraphs were separated with a special character: ¶, the <i>pilcrow</i>. Nowadays, this is considered claustrophobic and hard to read.</p> <p>How hard to read? See for yourself: <button data-toggle-text="Oh no! Switch back!">Use pilcrow for paragraphs</button> </p>
p {
margin: 0;
text-indent: 3ch;
}
p.pilcrow {
text-indent: 0;
display: inline;
}
p.pilcrow + p.pilcrow::before {
content: " ¶ ";
}
document.querySelector('button').addEventListener('click', function (event) {
document.querySelectorAll('p').forEach(function (paragraph) {
paragraph.classList.toggle('pilcrow');
});
var newButtonText = event.target.dataset.toggleText;
var oldText = event.target.innerText;
event.target.innerText = newButtonText;
event.target.dataset.toggleText = oldText;
});
Breaking up content into paragraphs helps make a page more accessible. Screen-readers and other assistive technology provide shortcuts to let their users skip to the next or previous paragraph, letting them skim content like how white space lets visual users skip around.
Using empty
<p>
elements to add space between paragraphs is problematic for people who navigate with screen-reading technology. Screen readers may announce the paragraph's presence, but not any content contained within it — because there is none. This can confuse and frustrate the person using the screen reader.
If extra space is desired, use
CSS
properties like
margin
to create the effect:
p {
margin-bottom: 2em; // increase white space after a paragraph
}
