As a senior security CMS website operator, I know the core position of content in website operation.High-quality content not only requires careful creation, but also needs to be presented in **English** to ensure user experience and the efficiency of information delivery.How to effectively handle automatic line breaks for long text content is the key to improving the readability and aesthetics of the page.The AnQi CMS maintains the integrity of content storage, but on the front-end display level, it provides flexible and diverse automatic line break solutions through its powerful template engine and rich filters.

Anqi CMS' way of managing long text content

In the Anqi CMS, whether it is articles, product details, or single page content, long text is usually stored in the content field (such asContent）中。The system will fully save all the text you input in the background editor, including manual line breaks or HTML tags.This means that the Safe CMS itself does not perform 'auto-wrap' processing on text during content saving, because auto-wrap is a concept of front-end display, which needs to be dynamically adjusted according to different screen sizes, layout design, and specific display requirements.Therefore, we need to implement automatic line breaks for long text on the page through template-level control.

Automatic line breaks are achieved through template tags and filters

The template engine of Anqi CMS supports template tags and filters similar to Django syntax, which are the key tools for us to implement automatic line breaks for long text and content truncation.These filters can process the content before it is output to the web page.

1.wordwrapFilter implementation for automatic line wrapping at specified length

When you want to automatically insert a line break at a certain character length within long text content, rather than just the default word break in browsers,wordwrapThe filter is very useful. It ensures that even a long string without spaces can be broken at the specified length, improving readability in narrow layouts.

For example, you have a very long string without spaces, or you want to force a line break every certain number of characters, you can usewordwrapFilter.

{{ archive.Content|wordwrap:50|safe }}

The above code willarchive.ContentThe text should be wrapped after every 50 characters. Please note,safeA filter is necessary to prevent HTML content from being escaped.

2.linebreaksandlinebreaksbrThe filter handles manual line breaks

The user may enter content in the background editor and create paragraphs or line breaks manually by pressing the Enter key.EnterHowever, HTML defaults to ignoring single line breaks in text.linebreaksandlinebreaksbrThe filter can convert these manual line breaks from background inputs into visible HTML structure on the web page.

  • linebreaksbrThe filter will convert individual newline characters in text into\n),<br />Tags, to implement line breaks in a single line.
  • linebreaksFilter further, it will convert two consecutive newline characters into\n\n),<p>tags, a single newline character is converted into<br />tags, thereby generating standard HTML paragraph structure.

In practical applications, if your content has been segmented by the editor, it is usually chosen tolinebreaksgenerate semantically meaningful paragraphs:

{{ archive.Description|linebreaks|safe }}

If you only need simple line breaks instead of generating new paragraphs:

{{ archive.Address|linebreaksbr|safe }}

3.truncatecharsandtruncatewordsFilter implementation for content truncation

Although strictly speaking, truncation is not automatic line-breaking, but in many cases, we may need to display an abstract of long text and then provide a 'Read more' link.This feature of truncation is very important, it indirectly solves the problem of displaying long text within limited space.

  • truncatecharsThe filter will truncate the text based on the specified number of characters and add an ellipsis at the end,...).
  • truncatewordsThe filter will truncate the text based on the specified word count and add an ellipsis at the end.

For example, display the article summary in the list of articles:

{{ item.Description|truncatechars:100 }}

This will display the first 100 characters of the introduction, followed by “…”.

4.truncatechars_htmlandtruncatewords_htmlSafely process HTML content with filters

Directly use for rich text content containing HTML tagstruncatecharsortruncatewordsIt may destroy the HTML structure, causing the page to display abnormally. Anqi CMS provides_htmla filter with suffix to solve this problem.

  • truncatechars_htmlandtruncatewords_htmlThe filter will intelligently close all unclosed HTML tags while truncating content, ensuring that the truncated content is still valid HTML.

If you need to truncate the article details,Contentand it may contain images, links, and other HTML elements, it is strongly recommended to use these filters:

{{ archive.Content|truncatewords_html:50|safe }}

This will automatically close the tags after truncating the content and add an ellipsis.

The auxiliary role of CSS in displaying long text

In addition to the content processing at the template level, the CSS style on the front end plays an important role in visually implementing automatic line breaks for long text. CSS properties such asword-wrap: break-word;/word-break: break-all;oroverflow-wrap: break-word;Can control how the browser handles long words or consecutive characters, ensuring they are automatically broken at the container boundary instead of overflowing the container.These CSS rules are usually applied to HTML elements containing long text, used in conjunction with the template filters of the Anqi CMS to provide a more perfect visual presentation.

Implementation and **Practice

In implementing automatic line break processing for long text in Anqi CMS, it is recommended to follow the following steps:

  1. Determine the display requirements:Clearly specify on which page and which area long text needs to be processed (e.g., the introduction on the list page, specific paragraphs on the detail page).
  2. Choose the appropriate filter:Select the most suitable filter based on whether to truncate, whether to include HTML, and whether to break by character or word.
  3. Apply in template:Edit the corresponding template file (e.g.,)detail.html/list.htmlAdd the selected filter to the variable that outputs long text content.
  4. Optimize with CSS:For a specific long text container, apply appropriate CSSword-wraporword-breakProperties to deal with extreme cases (such as extremely long words without spaces).
  5. Sufficient testing:Test the display effect of the page on different browsers and devices (PC, mobile) to ensure that the content is presented as expected.

Through these flexible template filters provided by AnQi CMS, we can easily perform refined control over long text content, whether it is automatic line breaking, truncating summaries, or safely handling HTML, we can find appropriate solutions, thus greatly enhancing the user experience and professionalism of the website.
