How to use `wordcount` to create dynamic styles based on content length in AnQiCMS template design?

In website content operation, we often encounter a challenge: how to keep the website interface beautiful and readable when displaying content of different lengths?A short news report and an in-depth industry analysis, they should be distinguished in terms of layout and style to provide a better user experience.AnQiCMS (AnQiCMS) fully understands this need and provides powerful and flexible tools in template design to solve this problem.Today, let's discuss how to use AnQiCMS'swordcountFilter, create a dynamic style based on the content length.

wordcountWhat is it? How does it work?

In the AnQiCMS template system,wordcountIt is a very practical filter, its main function is to calculate the number of "words" in a given string.The "word" is calculated based on the space-separated text fragments. When you willwordcountWhen applied to a content variable, it returns an integer representing the total number of words in the content.

For example, if you have a string"欢迎使用安企CMS，一个强大的内容管理系统"Pass it throughwordcountAfter filtering, a number will be obtained.

In simple terms, its usage is like this:

{{ "这是一个短句子"|wordcount }}

This code will output4.

Why should we use it in the templatewordcount?

UtilizewordcountFilter, we can implement various dynamic style requirements in the AnQiCMS template.Imagine that your website has both concise news and in-depth analysis long articles.By judging the number of words in the content, we can apply different CSS style classes to them, thus achieving visual distinction and layout optimization.

This not only enhances user experience, allowing users to identify the type of content at a glance, but also helps designers better control page elements, avoiding issues such as content overflow or excessive blank spaces. For example, we can decide based on the length of the content:

• Does the article summary card show the 'Read More' button or adjust the size of the summary?
• If the title in the list is too long, it can be automatically truncated or提示 with different colors.
• The detail page of the article adjusts the width of the main content area according to the length of the article, and even changes the display of the sidebar.

The ability to dynamically adjust the display according to the content is exactly the embodiment of the flexibility of AnQiCMS templates.

Implementing dynamic styles based on content length in the AnQiCMS template, the core lies in combiningwordcountfilter tags and conditional judgment tags (if/elif/else)。Below, we demonstrate its application through several specific scenarios.

1. Create dynamic styles and functions for the article summary card.

Assuming we have a list of articles, each article is displayed in card form, including the title, brief description, and link.We hope that the short summary is displayed directly, and the longer summary is truncated and a "Read More" button is provided.At the same time, apply different background colors to different-length summaries for distinction.

Firstly, we need to obtain a brief description of the article. In AnQiCMS, this is usuallyarchive.Descriptionfield.

{% archiveList archives with type="page" limit="10" %}
    {% for archive in archives %}
        {% set description_word_count = archive.Description|wordcount %}
        <div class="article-card {% if description_word_count < 30 %}card-short{% elif description_word_count < 80 %}card-medium{% else %}card-long{% endif %}">
            <h3><a href="{{ archive.Link }}">{{ archive.Title }}</a></h3>
            {% if description_word_count < 50 %}
                <p>{{ archive.Description }}</p>
            {% else %}
                <p>{{ archive.Description|truncatewords:45 }}...</p>
                <a href="{{ archive.Link }}" class="read-more-btn">阅读更多</a>
            {% endif %}
        </div>
    {% endfor %}
{% endarchiveList %}

In this code block:

• We first pass througharchive.Description|wordcountGet the number of words in the description and store it indescription_word_countthe variable.
• Next, according todescription_word_countvalue, dynamically add or removearticle-cardto the elementcard-short/card-mediumorcard-longThese CSS classes. These classes can be predefined in your stylesheet (CSS), for example, setting different background colors or border styles for cards of different lengths.
• At the same time, we also determine the display method of the summary based on the word count: if the description is short (fewer than 50 words), it is displayed in full; otherwise, it is truncated and a "Read More" link is added at the end.

2. Adjust the title style based on title length

In some list or navigation areas, a long title may disrupt the layout. We can apply different font sizes or colors based on the length of the title.

{% archiveList archives with type="list" limit="5" %}
    {% for archive in archives %}
        {% set title_word_count = archive.Title|wordcount %}
        <li class="article-item">
            <a href="{{ archive.Link }}" class="{% if title_word_count > 8 %}title-condensed{% else %}title-normal{% endif %}">
                {{ archive.Title }}
            </a>
        </li>
    {% endfor %}
{% endarchiveList %}

Here, if the number of words in the title exceeds 8, it should be appliedtitle-condensedClass (for example, it can be defined in a smaller font or truncated with an ellipsis), otherwise applytitle-normalClass.

3. Dynamically adjust the layout of the content area

For the article detail page, if the article content is particularly long, we may wish for it to occupy a wider page, to reduce the number of scrolls and enhance the reading experience.On the contrary, short articles can maintain the standard width.

{% archiveDetail archiveContent with name="Content" %}
    {% set content_word_count = archiveContent|wordcount %}

    <div class="article-detail-wrapper {% if content_word_count > 800 %}layout-wide{% else %}layout-standard{% endif %}">
        <h1>{{ archive.Title }}</h1>
        <div class="article-metadata">
            <span>发布日期：{{ stampToDate(archive.CreatedTime, "2006-01-02") }}</span>
            <span>阅读量：{{ archive.Views }}</span>
        </div>
        <div class="article-body">
            {{ archiveContent|safe }} {# 确保HTML内容安全输出 #}
        </div>
    </div>
{% endarchiveDetail %}

In this example, we retrieve the number of words in the article content. If it exceeds 800 words, we add the article container withlayout-wideA class, to make it wider in CSS; otherwise, uselayout-standardstandard layout.
