On the display of website content, the formatting of text is often a key factor affecting the user's reading experience.Sometimes, we wish the text could be forced to wrap at specific positions like in a Word document, rather than being automatically wrapped at word boundaries by the browser.Especially when displaying code, special formatted text, or when precise visual effects control is needed, this requirement becomes particularly important.For AnQiCMS users, with the flexible template system, we can easily achieve the effect of forced line breaks similar to Word documents, and we can also further control the text wrapping style in detail.

Understanding the implementation of 'forced line breaks' on web pages

Firstly, we need to clarify that in the context of web (HTML), 'forced line break' usually refers to inserting<br/>in a document.Shift + EnterThe effect of the key is similar, that is, a new line will start immediately at the cursor position regardless of whether the current line is full.The browser defaults to text auto-wrap, which is determined by the integrity of the word.

AnQiCMS template engine supports syntax similar to Django, which means we can take advantage of its powerful filters to process text content and achieve the layout effects we want.

UtilizelinebreaksbrFilter implementation for explicit line breaks

AnQiCMS's template system comes with a very practical filter namedlinebreaksbrThis filter's main function is to convert all line breaks in the text to HTML tags.\nautomatically.<br/>Labels. This is the core method to implement explicit line breaks similar to those in Word documents.

Usage:

Assuming your article content is stored inarchiveContentThis variable, and you hope to convert all the manual line breaks (such as when editing in the background, pressingEnter) to new lines on the web page, you can use it in the template like this:

{# 假设 archiveContent 变量包含了你希望处理的文本内容 #}
<div class="article-content">
    {{ archiveContent|linebreaksbr|safe }}
</div>

It should be noted that,|safeThe filter is indispensable. For safety reasons, AnQiCMS's template engine defaults to escaping all output HTML content, which<Converted to&lt;,>Converted to&gt;and. If not added|safe,linebreaksbrby the filter generator<br/>the tag will be displayed as plain text, not as a line break. Therefore,|safeensuringlinebreaksbrThe generated HTML tags can be rendered correctly.

The source of the text content and the impact of Markdown

In AnQiCMS, the main content such as articles or pages is usually stored inContentThis field may contain content generated by different editors, including rich text editors or Markdown editors.

  • Rich Text Editor:If the content is edited by a rich text editor, then you can directly press in the editorEnterkeys will be automatically inserted<br/>tags or wrap the text in<p>tags at this timelinebreaksbrThe filter may not be necessary (unless you need to process more inside these tags)\n).
  • Markdown Editor:If the Markdown editor is enabled (configurable in the "Global Settings" -> "Content Settings"), the Markdown syntax itself will handle line breaks. Usually, a hard return (entered directly in the Markdown source file)Enter）will be rendered based on context.<br/>Or they may be merged. Two hard returns will generate a new paragraph.<p>Tag).

Regardless of the content format,linebreaksbrthe filter can effectively handle existing text in\nCharacters.

More detailed control: use CSS to implement automatic text wrapping (not by word)

Sometimes, the user may not need to explicitly insert in the text<br/>Instead of a tag, it is desired that the text can automatically break at any character and wrap at the edge of the container, rather than adhering to the integrity of the word when wrapping.This is especially common in certain Chinese or Korean languages, as the concept of 'word' in these languages is not clear.

This 'non-word-based' automatic line break effect is mainly achieved through CSS, not through template filters. You can add the following CSS properties to HTML elements containing text:

.content-wrapper {
    word-break: break-all; /* 强制在任意字符处换行，包括单词内部 */
    /* 替代方案，更兼容旧版本浏览器：允许在单词内断开 */
    /* overflow-wrap: break-word; */
    /* word-wrap: break-word; /* IE和旧版浏览器兼容 */
}
  • word-break: break-all;This attribute will force the browser to break text at any character, even if the character is in the middle of a word, to achieve complete 'non-word' wrapping.
  • overflow-wrap: break-word;(or its old name)word-wrap: break-word;This property is relatively gentle, as it tries to wrap words between lines as much as possible. However, if a word is too long to be fully displayed within a line, it allows for breaking the word within.

Important reminder:Remember, the above CSS property controls the 'auto-wrap' behavior of text,linebreaksbrThe 'Explicit forced line break' inserted by the filter is two different concepts.You can choose one or both of them according to your actual needs to achieve **text formatting effects.linebreaksbrHandle manual line breaks in articles and ensure that long code lines wrap automatically at the container edge with CSS.

Through the flexible template system of AnQiCMS and the配合 of CSS, whether it is to explicitly insert line breaks or to implement automatic word-wrap without word boundaries, you can easily manage and optimize the display effect of website content.
