In the Aanqi CMS, the flexibility of website content display and layout is crucial to user experience.Especially for long text content, how to effectively control line breaks to avoid page overflow or destroy the beauty is a concern for many operators.wordwrapFilter can be combined with CSS to achieve more refined text wrapping control.

Get to know the AnQi CMS.wordwrapFilter

The template system of AnQi CMS adopts syntax similar to Django template engine, providing rich built-in tags and filters to help us flexibly handle content. Among them,wordwrapFilter is a powerful tool for processing long text line breaks.

wordwrapThe main function of the filter is to automatically wrap a long text to a specified length. Its working principle is to find the spaces between words in the text and then perform line breaks.

For example, we can use it like this in the template:

{# 假设archive.Content是一段很长的英文文本 #}
<div class="content-box">
    {{ archive.Content|wordwrap:80 }}
</div>

Here,|wordwrap:80This content will attempt to wrap at approximately 80 characters per line. The advantage of this is:

  1. Maintain word integrity:It will only break lines between words and will not split a word in the middle.
  2. Backend processing:The line break logic is already completed during the backend template rendering, which reduces the burden on the browser's frontend.

However,wordwrapThe filter also has a feature that needs attention: it is mainly designed for languages such as English that are separated by spaces. For languages with continuous characters such as Chinese, Japanese, and Korean,wordwrapThe filter does not force a line break between characters but treats the whole Chinese text as a single "word" for processing.This means that if your content is a continuous sequence of Chinese characters without spaces, even if you set a very small line break length, it may not automatically wrap, leading to content overflowing the container.

The powerful role of CSS in text wrapping

To make up forwordwrapThe CSS plays an indispensable role in overcoming the shortcomings of filters when handling continuous character languages, and implementing more flexible text wrapping control.CSS provides dedicated properties to control the text wrapping behavior, even for consecutive characters, to force line breaks.

Here are some commonly used CSS properties and their effects:

  1. word-break: break-all;This property will make the browser force a line break between any characters, even in the middle of a word.It is very suitable for processing languages without space separation such as Chinese, Japanese, and Korean, or when you need to ensure that super long English words or URL links do not overflow under any circumstances.
  2. overflow-wrap: break-word;(or in the old version of)word-wrap: break-word;This property tells the browser that a word (or a sequence of consecutive characters) should be allowed to break at any point within the word if it is too long to be displayed completely within the current line.break-all相比，它更倾向于保持单词的完整性，只在必要时才打断。
  3. white-space: pre-wrap;This property preserves whitespace and newline characters in the text, and wraps the text as needed. If you want the back endwordwrapnewlines generated by the filter (such as\nThis property will be very helpful as it can be retained and displayed as actual line breaks on the front end.

Through these CSS properties, we can more accurately control the line break effect of text in the visual layer, ensuring that the content can be presented elegantly under various screen sizes and layouts.

Flexible Control: Anqi CMSwordwrapCombination with CSS

To achieve truly flexible and robust text wrapping control, **it is necessary to combine the use of Anqi CMS**.wordwrapwith filters and CSS.

Scene one: Main content is in English, supplemented with long links or complex code.

For English content,wordwrapThe filter can be used to perform an initial, logical segmentation at the backend, ensuring a rough length for each line. Then, we can apply CSS to the HTML elements containing content.overflow-wrap: break-word;orword-break: break-all;As an “insurance”. This way, evenwordwraplong URLs or technical terms that cannot be processed can be forced to wrap with CSS, avoiding overflow.

Template example:

<div class="article-content">
    {{ article.Content|wordwrap:70 }} {# 后端初步按70字符换行，仅在空格处 #}
</div>

Corresponding CSS:

.article-content {
    width: 100%; /* 确保容器有明确宽度 */
    overflow-wrap: break-word; /* 避免长单词溢出 */
    word-break: break-word; /* 兼容性考虑，旧版浏览器可能只认word-break */
}

Scene two: Content contains a large amount of Chinese, or a mix of Chinese and English.

In this case, due towordwrapFilter's limitation on Chinese line break, we should rely more on CSS for line break control.word-break: break-all;oroverflow-wrap: break-word;Would be a more direct and effective choice. If the backend content (such as that collected or imported from outside) already contains newline characters (\n），and you hope that these newline characters are recognized and displayed by the browser, you can consider combiningwhite-space: pre-wrap;.

template example (output content directly):

<div class="mixed-content">
    {{ article.Content }} {# 不使用wordwrap，让CSS全权处理 #}
</div>

Corresponding CSS:

.mixed-content {
    width: 100%; /* 确保容器有明确宽度 */
    word-break: break-all; /* 强制中文或长英文在任意字符处换行 */
    /* 或者更保守的：overflow-wrap: break-word; */
}

In summary,wordwrapFilters and CSS are complementary rather than alternative. wordwrapAn English-based structured text length control is provided on the backend, while CSS offers pixel-level fine line-breaking capabilities on the frontend, playing a crucial role especially in handling non-Latin scripts or extremely long strings.Reasonably combining both can make the content display of the Anqi CMS website both aesthetic and flexible.

Practical suggestions and precautions.

  • Test compatibility:Different browsers and operating systems may have slight differences in the implementation of the CSS line break property, be sure to test on mainstream browsers.
  • Content Source:Consider the original format of the content. If it is an rich text editor input, it usually comes with HTML tags, and CSS line breaks will act on the internal text nodes. If it is plain text,wordwrapThe effect is more direct, but CSS is still the visual fallback.
  • Responsive design: On small screen devices, the text wrapping issue is particularly prominent. Combine responsive design to ensure that CSS wrapping rules perform well under different viewport sizes.

1. Secure CMS'swordwrapFilter can automatically wrap between Chinese?

Cannot.wordwrapThe filter mainly identifies spaces in English and other languages as line breaks.For continuous Chinese text, it treats it as a single word, does not automatically wrap between characters, and even with a very small line break length, it may cause content overflow.

2. When should we give priority to using?wordwrapWhen should we give priority to using CSS filter?

  • Prefer to usewordwrap:When your main content is English, and you want to perform preliminary, word-based text length control on the backend. This helps maintain the structure and readability of the content.
  • Use CSS first:When your content includes Chinese, Japanese, Korean, or other non-space-separated languages, or when you need to force long English words, URLs, or any other content to wrap to avoid overflow in containers.
