Have you ever wanted to break a long string of text into shorter lines after a certain number of words? This is a common requirement when designing responsive web layouts that adapt to different screen sizes. In this article, we'll explore how to achieve this effect with CSS.
word-wrap
PropertyThe word-wrap
property controls whether or not long words will wrap to the next line. By default, this property is set to normal
, which means that long words will overflow the container if there is not enough space. However, if we set word-wrap
to break-word
, long words will be broken and wrap to the next line.
p {
word-wrap: break-word;
}
This works fine if we want to break the text on any long word, regardless of its position in the text. However, if we want to break the text on specific intervals, such as after every 2 words, we need a different approach.
:nth-child
SelectorThe :nth-child
selector allows us to apply CSS styles to specific elements based on their position in a parent container. We can use this selector to target every second word in a block of text and insert a line break after it.
p span:nth-child(2n) {
display: block;
margin-bottom: 10px;
}
In this example, we're selecting every second span
element inside a p
element and setting its display
property to block
. This makes each second word appear on a new line. We're also adding a margin-bottom
property to create some spacing between the lines.
To break a block of text into lines after every 2 words, we combine the two techniques we've just learned:
p {
word-wrap: break-word;
}
p span:nth-child(2n) {
display: block;
margin-bottom: 10px;
}
This will apply the word-wrap
property to the entire block of text, and then insert a line break after every second word. The result will be a neatly formatted block of text that adapts to different screen sizes and avoids overflowing the container.
Breaking text into lines after a certain number of words is a useful technique for responsive web design. With CSS, we can achieve this effect by using the word-wrap
property to break long words, and the :nth-child
selector to insert line breaks after specific intervals. By combining these techniques, we can create well-formatted, responsive text that adapts to different screen sizes.
