the captcha area in AnQiCMSflex: 1The exquisite application: The art of CSS layout optimizing user experience

In scenarios such as comments, messages, or login on the website, captcha is an important link in ensuring information security and preventing malicious submissions. AnQiCMS cleverly utilizes the Flexbox model in modern CSS layout in its captcha module, one of which seems to be unremarkable.flex: 1Properties, in fact, play a key role in optimizing user experience and ensuring the responsiveness of page layout.

Let us first review the captcha integration code snippet provided by AnQiCMS:

<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;" />
  <script>...</script>
</div>

From this code, we can clearly see that the outermostdivcontainer is set todisplay: flexThis declares it as a Flexbox container.The core idea of Flexbox is to allow the container to control the layout of its internal items (flex item), including their alignment, direction, and distribution in available space.<input type="text">)and the captcha image(<img>).

Understandingflex: 1:a concise and powerful layout instruction

Now, let's focus on the captcha input box, which is equipped withstyle="flex: 1"this property. Although your question mentionedimgLabel, but according to AnQiCMS provided code,flex: 1Actually applied to the input box.

  1. flex-grow: 1This means that the flexible item (here being the captcha input box) is allowed to grow.When the Flex container has extra space, it will proportionally occupy these extra spaces.值为1表示它将占用所有可用的增长空间。
  2. flex-shrink: 1This means that the elastic item is allowed to shrink. When the Flex container does not have enough space, it will shrink proportionally. A value of 1 indicates that it will also shrink proportionally.
  3. flex-basis: 0%This defines the initial size of the elastic item before the available space is allocated.0%This means that the initial size of the input box is considered to be zero when calculating space allocation, thus completely relying onflex-growFill the space.

Combine with captcha image<img>Style of the labelwidth: 150px;height: 56px;Its function becomes very clear.The verification code image is assigned a fixed width and height, which means it will take precedence in the Flex container and occupy a width of 150 pixels.flex: 1If the property is indicated toFill all the remaining available space in the container after the fixed width of the image is subtracted.

  3.

  4. Simplify CSS code, improve development efficiency:Compared to traditional floating (float) or positioning (position) layout, Flexbox usesflex: 1Such concise properties can achieve complex adaptive effects, greatly reducing the amount of CSS code and maintenance cost.For AnQiCMS users, this means that they can adjust the captcha area style more efficiently and intuitively when customizing templates or doing secondary development.
