`slot` attributes are deprecated in `element` pop-up boxes. Instead, you should use the `v-slot` directive to define named slots. Here is an example:
```
<el-dialog title="Dialog Title" :visible.sync="dialogVisible">
<template v-slot:footer>
<span class="dialog-footer">
<el-button @click="dialogVisible = false">Cancel</el-button>
<el-button type="primary" @click="dialogVisible = false">Confirm</el-button>
</span>
</template>
</el-dialog>
```
In this example, the `footer` slot is defined using the `v-slot` directive. The `template` element with the `v-slot:footer` attribute defines the content of the slot.

`slot` attributes are deprecated
Yes, you are correct. The `slot` attribute has been deprecated in HTML5. It was used to define a placeholder for dynamic content in a web page. The recommended way to achieve this now is by using JavaScript or a templating language. The `data-*` attributes can be used to store custom data associated with an element.
vue2 `slot` attributes are deprecated
, what is the alternative in vue3?
In Vue3, instead of using `slot` with attributes, we can use the new `v-slot` directive along with named slots. We can define a slot with a name by using the `name` attribute, and then reference that slot using the `v-slot` directive with the same name. For example, if we have a component with a named slot named `header`, we can use it in Vue3 like this:
```
<template>
<my-component>
<template v-slot:header>
<h1>Header content goes here</h1>
</template>
</my-component>
</template>
```
Here, we are using the `v-slot` directive to reference the `header` slot and define its content.
