AnQiCMS comment captcha default CSS class name and style overlay tutorial

As an experienced website operations expert, I know that user experience and website security are equally important.AnQiCMS as an efficient and flexible content management system provides many practical functions to ensure website security, among which the留言验证码留言验证码is an important part to effectively prevent spam information.However, the default captcha style may not always perfectly fit the overall design of your website.Today, let's delve into what the default CSS class name of AnQiCMS comment captcha is, and how to elegantly override the styles in your theme to make it both secure and beautiful.

Understand the mechanism of AnQiCMS comment captcha

In AnQiCMS, the留言验证码function aims to enhance the security of the website's interactive area, effectively identifying and preventing malicious submissions by automated programs.When you enable the message comment captcha feature in the global settings of AnQiCMS background, the system will integrate this component into the front-end message or comment form.

From the documents provided by AnQiCMS, we can see that the captcha integration is implemented through specific template tags and a segment of JavaScript code. When the page loads, this JavaScript will send/api/captchaThe interface request verifies the captcha image and its corresponding ID, and dynamically displays it on the page. This process ensures the real-time and security of the captcha.

Unveil the default CSS class names and structure

To style the captcha, we first need to understand how it is presented in the HTML structure and what CSS classes are assigned by default. According to the example code in the AnQiCMS documentation, the captcha part usually contains the following core HTML elements:

<div style="display: flex; clear: both">
  <input type="hidden" name="captcha_id" id="captcha_id">
  <input type="text" name="captcha" required placeholder="请填写验证码" class="layui-input" style="flex: 1">
  <img src="" id="get-captcha" style="width: 150px;height: 56px;cursor: pointer;" />
  <!-- ... JavaScript for captcha loading ... -->
</div>

We can clearly identify several key style targets from this code:

1. Captcha input box (<input type="text">):

   • It has a default CSS class name:layui-input.This usually indicates that AnQiCMS may have integrated or referenced the style specifications of the LayUI framework on the frontend UI level.If your website theme does not use LayUI or you want to customize it completely, this class name is the starting point for you to override.
   • In addition, it also has aname="captcha"Properties can also be used as CSS selectors for positioning, for example.input[name="captcha"].
   • There is also an inline style.style="flex: 1"This means it will take up the remaining space in the flex layout.

2. Captcha image (<img>):

   • It does not have an explicit CSS class name, but it has a unique ID:id="get-captcha". The ID is one of the highest priority selectors, which is very suitable for precise positioning.
   • The image itself also contains some important inline styles:style="width: 150px;height: 56px;cursor: pointer;"These inline styles directly define the image size and hover effect.

3. The overall container of the captcha (<div>):

   • ThisdivWrapping the input box and image, and with an inline style:style="display: flex; clear: both". This makes the input box and image display side by side and clear the float.

Understanding these default class names, IDs, and inline styles is the foundation for effective style overriding.

Strategies for style overriding within themes

In AnQiCMS, theme files are usually stored in/template/{您的主题名称}/directory. For comment captcha, the related template files are probablyguestbook/index.htmlorguestbook.html(Please refer to your theme structure or AnQiCMS template design conventions for the specific file name). Style overrides usually follow these steps:

1. Locate and edit the template file

Firstly, you need to log in to the AnQiCMS backend, find the corresponding template file of the current theme using the "Template Design" feature. For example, if it is a message form, you will find something similar toguestbook/index.htmlThe file. In edit mode, you can view the HTML structure mentioned above.

2. Introduce custom CSS

To maintain code neatness and maintainability, it is strongly recommended that you perform style overrides in the theme's CSS file. Typically, your theme will have a main CSS file, such as/public/static/css/style.cssOr, inbash.htmlThe other CSS files introduced in the (Public Header Template). You can add your custom styles in these files, or create a newcustom.cssfile and introduce it.

3. Specific Style Overriding Method

With the target HTML element and CSS file, the next step is the specific overriding operation.

• Directly override using default class names and IDs:This is the most direct way. You can directly targetlayui-inputClass andget-captchaID writes CSS rules. Please note the CSS priority, if your CSS file is loaded after the default style, it can usually be directly overridden.

  /* 覆盖验证码输入框的样式 */
  .layui-input[name="captcha"] {
      border: 1px solid #007bff; /* 更改边框颜色 */
      border-radius: 4px;      /* 更改圆角 */
      height: 40px;            /* 调整高度 */
      padding: 0 10px;         /* 调整内边距 */
      background-color: #f8f9fa; /* 更改背景色 */
      font-size: 16px;         /* 调整字体大小 */
      /* !important 慎用，仅在优先级问题无法解决时考虑 */
      /* width: auto !important; */ 
  }
  
  
  /* 覆盖验证码图片的样式 */
  #get-captcha {
      border: 1px solid #ced4da; /* 更改边框 */
      border-radius: 4px;      /* 更改圆角 */
      /* 覆盖内联样式需要更高的优先级，或者在模板中移除内联样式 */
      width: 120px !important; /* 强制覆盖宽度，注意 !important 的使用 */
      height: 40px !important; /* 强制覆盖高度 */
      margin-left: 10px;       /* 调整与输入框的间距 */
  }
  

  It is especially important to note here,layui-inputThere may be the default style of LayUI framework,#get-captchaThe inline style. To ensure that your custom styles take effect, you may need a higher CSS selector weight (such as combining with parent elements, or using more specific selectors likeinput[name="captcha"])，even if necessary!important(but it should be avoided as much as possible)

• Modify the HTML structure and add a custom class name:It is recommended to modify the HTML structure in the template without affecting the captcha function, and add your own semantic class names to the captcha container, input box, or image.This can avoid conflicts with the default framework styles, improving the readability and maintainability of the code.

  In the template file, you can modify the original code to:

  <div class="anqicms-captcha-wrapper">
    <input type="hidden" name="captcha_id" id="captcha_id_custom">
    <input type="text" name="captcha" required placeholder="请填写验证码" class="anqicms-captcha-input">
    <img src="" id="anqicms-captcha-image" />
    <!-- ... JavaScript for captcha loading ... -->
  </div>
  

  English, also remember to modify the JavaScript referencesid="captcha_id"andid="get-captcha"to your new ID, for exampleid="captcha_id_custom"andid="anqicms-captcha-image".

  Then, you can safely use the new class names and IDs for style definition in CSS files: “`css .anqicms-captcha-wrapper {

  display: flex;
  align-items: center; /* 垂直居中 */
  gap: 10px;           /* 间距 */
  margin-bottom: 15px; /* 下方间距 */
  /* 清除浮动等，如果您是从原div复制内联样式 */
  

  }

  .anqicms-captcha-input {

  border: 1px solid #ced4da;
  border-radius: 5px;
  padding: 8px 12px;
  font-size: 14px;
  flex: 1
