How to use: first-line pseudo-element selector to change the CSS style of the first line of text in each line of a paragraph, you need specific code examples
CSS pseudo-element is A selector commonly used in CSS to specify a specific part or state of an element. Among them, the :first-line pseudo-element selector is used to select the first line of text in the element and apply a specific CSS style to it.
In HTML, we can create a paragraph of text by wrapping the paragraph in a
tag. Next, we will use the :first-line pseudo-element selector to change the text style of the first line in each paragraph.
The code sample is as follows:
HTML code:
<!DOCTYPE html> <html> <head> <title>使用:first-line伪元素选择器改变段落中每行的第一行文字的CSS样式</title> <link rel="stylesheet" type="text/css" href="style.css"> </head> <body> <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed cursus vestibulum tortor, quis pulvinar metus dapibus ut.</p> <p>Phasellus ultrices mauris et dolor cursus, quis consectetur diam commodo. Nam feugiat tortor id.</p> <p>Vestibulum nec ipsum vitae mauris condimentum ultricies in sed ligula. Donec quis odio in dui.</p> </body> </html>
CSS code (style.css):
p:first-line {
font-weight: bold;
font-size: 20px;
color: red;
}In the above example, we are in CSS The :first-line pseudo-element selector is used, and p:first-line is used as the selector to specify that a specific style is to be applied to the first line of text in each paragraph
.
In the CSS code, we changed the style of the first line of text, setting it to bold (font-weight: bold), the font size to 20 pixels (font-size: 20px), and the color to red (color: red).
With such a simple CSS code, we can render the first line of text in each paragraph in a different style to better highlight the important content in these texts.
It should be noted that the :first-line pseudo-element selector can only be applied to block-level elements, such as
,
By using the :first-line pseudo-element selector, we can easily change the CSS style of the first line of text in each line of a paragraph, making the text more visually appealing and grabbing the reader's attention.
