In AnQiCMS template, the practical guide to implementing banner image rotation effect

In modern website design, Banner image carousel (Carousel) is almost an essential feature for every corporate website and portal.It can effectively attract visitors' attention and also display multiple important products, services, or brand information within a limited space.AnQi CMS, with its concise and efficient architecture and support for Django template engine syntax, allows website operators to easily integrate and manage banner carousel effects in templates.

This article will provide you with a comprehensive practical guide around the Anqi CMS, from backend preparation to template integration, and finally to the implementation of frontend interaction.

一、Background preparation: Build your Banner content library

Before starting with the template code, we first need to configure the images and their relevant information required for the carousel in the Anqi CMS backend management system. Anqi CMS provides various methods to manage banners, allowing you to choose flexibly according to your actual needs:

  1. Home Page Banner Management:Anqy CMS usually comes with a built-in Banner management feature for the website homepage. Here, you can upload multiple images, set titles, descriptions, redirect links, and importantAltText (used as alternative text when the image cannot be displayed, also very crucial for SEO). These images are usually assigned to a default Banner group.

  2. Category or Single Page Banner Configuration:In addition to the global homepage Banner, AnQi CMS also supports setting exclusive Banner carousel for specific category pages or independent single pages.

    • Category Banner:In the background, go to "Content Management" -u003e "Document Categorieshelp-content-category.md）。You can upload a set of Banner images for this category here.
    • Single-page Banner：Similarly, when editing a single page in "Page Resources" -u003e "Page Managementhelp-source-page.md).

Key tips:Ensure that the dimensions of the uploaded images are consistent to maintain the coordination and aesthetics of the carousel, no matter which Banner it is. At the same time, fill in clear and accurate information for each image.AltText, this not only improves the accessibility of the website, but also is very beneficial for search engine optimization.

Part two: Template integration: Use AnQiCMS tags to obtain data

Once the Banner image and information on the backend are ready, the next step is to call these data in the front-end template and construct the HTML structure. Template tags of Anqi CMSbannerListIt is a powerful tool to achieve this core function.

  1. Confirm the location of the template file:Generally, the Banner carousel is placed on the homepage of the website (index/index.htmlorindex.html), the category list page ({模型table}/list.html) or the single page detail page (page/detail.html). According to where you want to display the Banner, edit the corresponding template file. The default location of template files for Anqi CMS is/templatedirectory, and named with.htmlwith suffix (refer todesign-convention.md).

  2. IntroductionbannerListTags: bannerList标签用于获取后台配置的 Banner 列表。它是一个循环标签，您可以像处理数组一样遍历其内部的每个 Banner 项。

    {% bannerList banners %}
    {# 在这里循环输出每个 Banner item #}
{% endbannerList %}

    bannersIs the variable name you define for the Banner list, you can name it freely, but it must be consistent with the internalforvariable in the loop.

  3. Build the basic HTML structure:InbannerListLabel inside, we usefora loop to traverse each Banner image. Each Banner item (item) containsLogo(Image address,)Link(Link address,)Alt(Image Alt text),Title(Title) andDescription(Description) fields (refer to)tag-/anqiapi-other/3498.html).

    A basic Banner carousel HTML structure may look like the following, please noteitem.Titleanditem.DescriptionThe field will be displayed according to the backend settings:

    <div class="main-banner-carousel">
    <div class="swiper-wrapper"> {# 假设使用 Swiper.js 轮播库 #}
        {% bannerList banners %}
            {% for item in banners %}
            <div class="swiper-slide">
                <a href="{{item.Link}}" {% if item.Link %}target="_blank"{% endif %}>
                    <img src="{{item.Logo}}" alt="{{item.Alt}}" class="img-fluid">
                    {% if item.Title %}
                    <div class="banner-caption">
                        <h3>{{item.Title}}</h3>
                        {% if item.Description %}<p>{{item.Description}}</p>{% endif %}
                    </div>
                    {% endif %}
                </a>
            </div>
            {% endfor %}
        {% endbannerList %}
    </div>
    {# 如果需要，这里可以添加轮播控制按钮和分页器 #}
    <div class="swiper-button-next"></div>
    <div class="swiper-button-prev"></div>
    <div class="swiper-pagination"></div>
</div>

  4. Realize front-end interaction withactiveStatus:The Auto CMS is responsible for providing content data, while the actual carousel animation effect needs to be implemented by the front-end CSS and JavaScript.通常，我们会引入一个成熟的前端轮播库，例如 Swiper.js、Slick Carousel 或 Owl Carousel 等。

    These libraries usually need to add a class to the first Banner elementactivefor the Safe CMS template.forloop.CounterVariables can help us easily achieve this:

    `twig

    <div class="swiper-wrapper">
    {% bannerList banners %}
        {% for item in banners %}
        <div class="swiper-slide {% if forloop.Counter == 1 %}swiper-slide-active{% endif %}"> {# 注意：类名可能因轮播库而异 #}
            <a href="{{item.Link}}" {% if item.Link %}target="_blank"{% endif %}>
                <img src="{{item.Logo}}" alt="{{item.Alt}}" class="img-fluid">
                {% if item.Title %}
                <div class="banner-caption">
                    <h3>{{item.Title}}</h3>
                    {% if item.Description %}<p>{{item.Description}}</p>{% endif %}
                </div>
                {% endif %}
            </a>
        </div>
        {% endfor %}
    {% endbannerList %}
</div>
<div class="swiper-button-next"></div>
<div class="swiper-button-prev"></div>
<div class="swiper-pagination"></div>
