How to set both ends to be aligned in css? A brief analysis of various methods

In website layout, text alignment is a very important part. We usually use left, center and right alignment. However, in some cases, we need to use justified, also called "justified". Justification distributes text evenly and improves visual impact. While justified is becoming less and less common in modern web design, it’s still a very useful technique when you need it.

There are many ways to achieve alignment at both ends. In this article, we’ll cover some of the most common techniques, from basic CSS to some advanced techniques.

Basic CSS Tips

Basic CSS tips are the simplest, but sometimes the best way to achieve alignment. We can use the text-align attribute to set the text to justify, as shown below:

p {
  text-align: justify;
}

This simple CSS rule will align both ends of the paragraph text. This can produce very good results in some situations, but may not be so great in others. This is because when CSS is justified, each line of text fills the entire width, causing uneven spacing. This may not look pretty, but there are a few ways we can fix this. An easy way to do this is to increase the kerning, via the letter-spacing property:

p {
  text-align: justify;
  letter-spacing: 2px;
}

This will add 2 pixels of space between paragraph text. Although this may cause some words to be broken into multiple words and line breaks at inappropriate places. However, if your text is primarily in English, this isn't much of a problem. However, if your text is in Chinese, you may want to increase the kerning between Chinese and English.

To avoid words being broken up, we can use another CSS property: text-justify. text-justify is a part of CSS3 that controls how lines of text are aligned. Three values ​​are available for this attribute: auto, none, and inter-word. auto is the default value, and rows are aligned with left, right, and center types. inter-word uses the spacing between words and the spacing between words to achieve alignment at both ends. Of course, you may see some irregular whitespace characters, especially in the middle of words. This is usually caused by differences between various languages.

Another trick to keep words intact is to use word wrapping. This will cause long words to be broken up at the appropriate places and avoid word splitting. You can use the following style rules:

p {
   text-align: justify;
   word-break: break-all;
}

This will break words everywhere and align the text in the margins. It's more complex than the letter-spacing property, but for scenarios where English text needs to be aligned, it's an option to consider.

Advanced CSS Tips

The above CSS tips work well for simple web projects. However, if you want to spread the text evenly without breaking the words or text formatting, you may need some advanced techniques.

Evenly distribute child elements within a container by using Flexbox

Flexbox layout is a new CSS layout system that allows you to have better control and layout of your website. We can use the Flexbox function of modern browsers to achieve alignment on both ends. In order to use Flexbox layout, we need to set display:flex to the container.

.container {
  display: flex;
  justify-content: space-between;
}

This style rule will evenly distribute all elements in the container while maintaining its own format. The space-between value ensures appropriate white space between child elements within the container, thereby achieving alignment. This approach also has the advantage of adapting to different screen sizes through responsive design.

Use CSS Grid to evenly distribute child elements within the container

CSS Grid is another modern CSS layout system that is more flexible and powerful than Flexbox. We can use Grid to achieve alignment at both ends:

.container {
  display: grid;
  grid-template-columns: repeat(auto-fit, minmax(200px, 1fr));
  grid-gap: 20px;
  justify-items: stretch;
  align-items: center;
}

This rule does a lot of things. First, it makes the container a grid and sets the number of columns for the repeating grid and the minimum and maximum width of each column. Next, it defines a spacer to separate child elements. Finally, it sets the justify-items property to evenly distribute the child elements, and the align-items property to vertically center all child elements in the container. This method requires professional CSS skills, but the results are very effective.

Conclusion

Although justified is not an indispensable element in every website design, it is a very useful technique that can improve visual effects. From basic using the text-align property to advanced using Flexbox and Grid layout, we explore different techniques in this article to achieve alignment. No matter what your website needs, these tips can go a long way to improving the readability and aesthetics of your website.
