uniapp is a cross-platform application development framework based on the Vue.js framework, supporting multi-terminal (including H5, small programs, App, etc.) development. In uniapp, the radio component is the component used for radio buttons, usually used to select one or more items. However, by default, the size of uniapp's radio component is fixed and cannot be adjusted directly.

So how to adjust the size of the radio component of uniapp?

To address this problem, we can solve it in the following two ways:

Method 1: Adjust the size of the radio component through CSS styles

We can set it in the page CSS styles to adjust the size of the radio component. First, we need to use a CSS selector to select the radio component that needs to be resized, and then set its width and height through the width and height properties. For example, the following CSS style sets the width and height of the radio component to 30px:

.radio {
  width: 30px;
  height: 30px;
}

Method 2: Use the radio-group component that comes with uniapp

Uniapp provides a radio-group component, which can combine multiple radio components so that they can be combined as a whole control. Moreover, it provides the size attribute to control the size of the entire radio-group component, thereby achieving the purpose of adjusting the size of the radio component. For example, the following example sets the size of the radio-group component to 40px:

<radio-group size="40">
  <radio value="1">选项一</radio>
  <radio value="2">选项二</radio>
  <radio value="3">选项三</radio>
</radio-group>

It should be noted that this method requires adding multiple radio components to the same radio-group component, so it is suitable for needs Perform uniform resizing of the scene.
