When building website content, we often need to finely format the text to ensure that the information is presented both beautifully and clearly.Whether it is a list, table, product parameters, or other data that needs to be displayed structurally, maintaining visual alignment and consistency is crucial for enhancing user experience.AnQi CMS, known for its high flexibility and ease of use as a content management system, deeply understands the importance of content presentation and has built-in a series of powerful template filters to help us easily achieve various alignments and centering of strings.

This article will delve into how to use built-in filters in AnQiCMS to center, left-align, or right-align strings according to specified lengths, making your website content more professional and unified.

Easily master the string alignment and centering filter of AnQiCMS

AnQiCMS's template system adopts syntax similar to Django's template engine, which means we can handle variables through concise filter syntax. For string alignment and centering, AnQiCMS providescenter/ljustandrjustThese are very practical filters. They all work by surrounding the string with spaces to reach the specified total length.

Let us understand their functions and usage one by one.

Centered display:centerFilter

centerThe filter, as the name suggests, is to display the string centered within its specified length.If the length of the original string is less than the specified total length, spaces will be automatically filled on both sides of the string to reach the specified total length.An interesting detail is that if the total number of spaces to be filled is odd, it will default to having one less space filled on the right than on the left to maintain a sense of relative centering.

Usage:

{{ obj|center:长度 }}

Example demonstration:

Suppose we want to center the string 'Hello World' within a width of 20 characters:

'{{ "你好世界"|center:20 }}'

This code will execute and you will see the following output:

'        你好世界        '

Here, "Hello, World" occupies 4 character widths (each Chinese character is counted as one character), and the remaining 16 characters are filled with spaces.Since 16 is an even number, 8 spaces were filled on each side.

Let's take another example where an odd number of spaces need to be filled in:

'{{ "test2"|center:19 }}'

The output will be:

'       test2       '

The word 'test2' occupies 5 characters, with 14 characters remaining. However, the total length is 19,centerThe total number of characters to be filled will be calculated.19 - 5 = 14an empty space. These 14 spaces will be distributed on both sides. But if the total number of fillings is odd, it will try to have one less on the right side to maintain relative centering. In fact, the example in the document istest2At length 20, it is' test2 'Left 8, right 7.When the length is 19, then left 7 and right 7.The width calculation of Chinese and English characters may be slightly different, but the principle is consistent: intelligently allocate padding characters within a specified length to achieve centering.

Left aligned:ljustFilter

ljustThe filter then focuses on left-aligning strings.If the length of the original string is less than the specified total length, it will be padded with spaces on the right until it reaches the specified total length.This is very useful for list items or table columns that need to be aligned to the left.

Usage:

{{ obj|ljust:长度 }}

Example demonstration:

Left align 'Hello, World' within a 10-character width:

'{{ "你好世界"|ljust:10 }}'

The output result will be:

'你好世界      '

“Hello World” occupies 4 character widths, and 6 spaces are filled on the right to make the total length 10.

Right-aligned:rjustFilter

WithljustThe filter is opposite,rjustThe filter aligns the string to the right.It will pad spaces on the left side of the string until the specified total length is reached.This is very suitable for scenarios such as numeric data or headers that need to be right-aligned.

Usage:

{{ obj|rjust:长度 }}

Example demonstration:

Right-align 'Hello World' within a 10-character width:

'{{ "你好世界"|rjust:10 }}'

The output result will be:

'      你好世界'

Similarly, 'Hello World' occupies 4 character widths, and 6 spaces are filled on the left to make the total length 10.

Actual application scenarios and content operation value

These aligned strings of the filter seem simple, but they can play a huge role in actual content operation.

  1. Unified display of table and list data:Whether it is a product parameter table, price list, or service description, aligning the filter ensures the visual length of each item is unified, providing a better browsing experience for users and enabling them to quickly obtain information.
  2. Dynamic content block:Under the flexible content model of AnQiCMS, we often need to dynamically generate news summaries, article titles, or product descriptions.Aligning by specified length ensures that the final displayed content blocks are uniform even if the original string lengths are not.
  3. Personalized reports and notifications:If you need to generate some internal reports or user notifications that include data in a specific format, these filters can help you maintain the alignment of data columns in text reports and improve readability.
  4. SEO Friendliness (Indirect):Although the direct impact is not significant, optimizing the details of content display can improve the user's dwell time on the page (by improving the reading experience), as well as reduce the bounce rate, all of which help to pass positive user signals to search engines, thus indirectly optimizing the SEO effect.

By skillfully applying these filters, you can ensure the professionalism and consistency of the website content, providing users with a better browsing experience, and also greatly enhancing the efficiency of content maintenance and template design.

Common Questions (FAQ)

If the actual length of the string exceedscenter/ljustorrjustHow will it be if the total length specified by the filter?

Answer: When the actual length of the string exceeds the total length you specify, these filters will not truncate the string.They will display the full string as it is, without any padding or truncation.This means that your content will not lose information due to alignment settings.

2. Can I use other characters besides spaces to pad the string?

Answer: AnQiCMS built-incenter/ljustandrjustThe filter default can only be filled with spaces. If you need to use other characters (such as asterisks*or dashes-Fill in the parentheses, you may need to combine other filters or custom template logic to achieve this. A common method is to first use these filters to generate a string with spaces, then usereplaceThe filter replaces spaces with other characters.

3. Does the string alignment filter support Chinese content? How many characters is a Chinese character counted as when calculating length?

Answer: Yes, these filters fully support Chinese content.When calculating the length of a string (whether it is the original length or the total length after specified padding), AnQiCMS's template system will intelligently calculate according to the UTF-8 character count, that is, one Chinese character is counted as one character length, consistent with English numbers.Therefore, you can safely apply them to text containing Chinese.
