When building and maintaining website content, we often need to pay attention to the visual effects of information presentation, especially the alignment of text content.Whether it is for the neat and beautiful table, or to maintain visual balance within a fixed width area, precise control of the centering, left alignment, or right alignment of strings is particularly important.AnQiCMS With its flexible and powerful template engine, it provides us with several very practical filters to easily achieve this goal, even for strings containing Chinese characters.

Today, let's delve deeper intocenter/ljustandrjustThese three filters, see how they help us align Chinese character strings to a specified width in AnQiCMS templates.

Smart centering:centerFilter

As the name suggests,centerThe filter helps us center the string content within its specified width.When you need to keep a Chinese title or phrase centered in a fixed-width container, it comes in handy.

It fills half-width spaces on both sides of the string until the total length of the string reaches the target width you set.AnQiCMS's template engine is very intelligent in handling Chinese characters, it treats each Chinese character as a width unit and then performs precise space padding based on this.

The method of use is very intuitive, just add the pipe symbol after the variable|andcenter:目标宽度English

'{{ "安企CMS"|center:20 }}'

This code execution will show you output similar to this:

'        安企CMS         '

Here, 'AnQi CMS' occupies 5 character widths (when calculating, one Chinese character is considered as one width unit), and the remaining 15 widths are filled with spaces, with about 7-8 spaces on each side. It is worth mentioning that when the difference between the target width and the length of the string is odd,centerThe filter will prioritize less space on the right to maintain centering as much as possible.

Stable aligned to the left:ljustFilter

If your Chinese content needs to be aligned to the left and you also want to leave a fixed padding space on the right, thenljustFilter is your ideal choice. It will fill half-width spaces on the right side of the string, pushing the content to the left.

Similarly,ljustThis filter is very useful when you want to keep the Chinese descriptions aligned on the left side of the list or table and leave white space on the right.

The way it is used iscenterSimilar, just need to,centerwithljust:

'{{ "内容管理系统"|ljust:20 }}'

Run this code, you will see that the "Content Management System" is displayed to the left within a 20-character width, with spaces filled on the right:

'内容管理系统              '

Precisely aligned to the right:rjustFilter

WithljustOn the contrary,rjustFilter aligns the string content to the right and fills the necessary half-width spaces on the left. This is particularly useful in scenarios where numbers need to be aligned or short annotations are displayed on the right.

For example, you may want to align Chinese numerals or dates to the right within a display area of fixed width to enhance the visual order.

The usage is also simple:

'{{ "解决方案"|rjust:20 }}'

After execution, the result will be like this, the string "Solution" is displayed to the right, and the left side is filled with spaces:

'            解决方案'

Important tips and practical applications

These three filters have a common rule, that is, if the length of the original string has alreadyexceeded or is equal toThe width you set, so the filter will not make any changes, directly return the original string. This is to prevent accidental truncation of the original content, ensuring the integrity of the information.

In practical applications, these filters are most commonly used in scenarios that require fixed-width display, such as:

  • Table or list:Ensure that the content in the table columns, whether Chinese or English, is aligned visually.
  • Product or article summary:Beside the thumbnail, the title or brief description can be kept aligned with these filters to maintain a fixed length, making the layout more standardized.
  • Sidebar navigation:Work with CSS styles to create fixed-width navigation menus with better visual effects.
  • Data report:Align numbers or short text to present data more clearly.

When using these filters, we recommend trying to adjust the width of the parent element in the browser's developer tools, and observe the alignment effect of the string to find the most suitable width value.This can better ensure that your content maintains the expected visual effects on different devices and screen sizes.

By using flexibilitycenter/ljustandrjustFilter, it allows the Chinese content on the AnQiCMS website to present higher professionalism and a better user experience.They are an indispensable helper when you are designing templates and formatting content.

Common Questions (FAQ)

Q1: Why does my Chinese string not work when usingcenteror other alignment filters but no effect?

A1: This situation usually occurs for several reasons.Firstly, the target width you set may be less than or equal to the actual length of the Chinese string itself. In this case, the filter will not perform any padding or truncation, but will return the original string directly.<pre>fixed width columns within tags or columns withwidthattributesdivCheck the effect in English, otherwise the browser may automatically adjust the layout to make the filled spaces less obvious.

Q2: These filters calculate the 'width' of Chinese characters how? How many spaces is a Chinese character counted as?

A2: AnQiCMS template engine is processingcenter/ljust/rjust

Q3: Can I use other characters (such as asterisks or dashes) to replace spaces for padding?

A3: AnQiCMS templates built-incenter/ljust/rjustThe default filter design only uses half-width spaces for padding, and does not directly support custom padding characters.If you need to use other characters for padding, you may need to consider combining string replacement filters or by writing custom template functions to achieve this, but it will be more complex than using built-in filters.
