Cascading Style Sheets (CSS) play a crucial role in web development by allowing developers to style and design the appearance of their web pages. One essential aspect of CSS is text styling, and among the numerous properties available, the CSS text-anchor property stands out. In this article, we'll explore what CSS text anchors are, how they work, and how they can be used to enhance the presentation of text on a website.
CSS Text Anchor Basics
The CSS text-anchor attribute is closely linked with SVG (Scalable Vector Graphics) and specifies the alignment of text inside a text container. This attribute impacts the positioning of the text in relation to a specific point or region, giving authority over its placement.
Syntax:
The fundamental format for the text-anchor attribute appears as below:
text-anchor: start | middle | end | inherit;
- Start: Align the text to the start of the text container.
- Middle: Align the text to the middle of the text container.
- End: Align the text to the end of the text container.
- Inherit: Inherits the value from the parent element.
Understanding Text Anchor Values:
1. Start:
The "start" setting positions the text flush with the start of the text container. In languages that read from left to right like English, this corresponds to the left edge of the container.
Code:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>JTP</title>
<style>
svg {
width: 100%;
height: 100px;
border: 1px solid #ccc;
}
text {
font-family: Arial, sans-serif;
font-size: 16px;
fill: #333;
/* Text color */
text-anchor: start;
}
</style>
</head>
<body>
<div class="container">
<svg>
<text x="10" y="50">Start Anchored Text</text>
</svg>
</div>
</body>
</html>
Output:
2. Middle:
The "middle" value aligns the text in the center of the text container, guaranteeing balanced spacing on either side.
Code:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>JTP</title>
<style>
svg {
width: 100%;
height: 100px;
border: 1px solid #ccc;
}
text {
font-family: Arial, sans-serif;
font-size: 16px;
fill: #333;
/* Text color */
text-anchor: middle;
}
</style>
</head>
<body>
<div class="container">
<svg>
<text x="10" y="50">Start Anchored Text</text>
</svg>
</div>
</body>
</html>
Output:
3. End:
The "end" parameter positions the text to the opposite end of the text container. In languages that read from left to right, this corresponds to the right side of the container.
Code:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>JTP</title>
<style>
svg {
width: 100%;
height: 100px;
border: 1px solid #ccc;
}
text {
font-family: Arial, sans-serif;
font-size: 16px;
fill: #333;
/* Text color */
text-anchor: end;
}
</style>
</head>
<body>
<div class="container">
<svg>
<text x="10" y="50">Start Anchored Text</text>
</svg>
</div>
</body>
</html>
Output:
4. Inherit:
The "inherit" keyword enables the text-anchor property to derive its value from the containing parent element.
Code:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>JTP</title>
<style>
svg {
width: 100%;
height: 100px;
border: 1px solid #ccc;
}
text {
font-family: Arial, sans-serif;
font-size: 16px;
fill: #333;
/* Text color */
text-anchor: inherit;
}
</style>
</head>
<body>
<div class="container">
<svg>
<text x="10" y="50">Start Anchored Text</text>
</svg>
</div>
</body>
</html>
Output:
Practical Applications
1. SVG Elements:
The text-anchor attribute is frequently utilized in SVG elements to manage the positioning of text inside shapes or containers. For instance, in a bar graph, it is recommended to align the data labels to the right end of each bar.
Code:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>JTP</title>
<style>
svg {
width: 200px;
height: 100px;
border: 1px solid #ccc;
}
text {
font-family: Arial, sans-serif;
font-size: 16px;
fill: #333;
/* Text color */
text-anchor: middle;
}
</style>
</head>
<body>
<div class="container">
<svg>
<text x="100" y="50">Centered Text</text>
</svg>
</div>
</body>
</html>

Advanced Usage and Considerations
1. Multiple Lines and Text Spans:
When working with multiline text or text spans within a container, you can apply the text-anchor property to each text element separately. This feature enables precise adjustment of the alignment for each line or span, thereby improving the visual hierarchy of the content.
Code:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>JTP</title>
<style>
svg {
width: 200px;
height: 120px;
border: 1px solid #ddd;
background-color: #f5f5f5;
}
text {
font-family: 'Arial', sans-serif;
font-size: 16px;
fill: #333;
/* Text color */
font-weight: bold;
}
.line1 {
text-anchor: start;
}
.line2 {
text-anchor: middle;
}
.line3 {
text-anchor: end;
}
</style>
</head>
<body>
<div class="container">
<svg>
<text x="10" y="50" class="line1">First line</text>
<text x="100" y="70" class="line2">Second line</text>
<text x="190" y="90" class="line3">Third line</text>
</svg>
</div>
</body>
</html>
