Tips for optimizing form layout and styles in Vue pages

introduction

In daily development, form layout and style optimization in Vue projects are an important link. Through reasonable layout and beautiful style design, it can not only improve the user experience, but also increase the practicality and viewing of the page. This article will summarize several common forms and table layout optimization techniques, from how to adjust table layout, add scroll bars, to how to move the entire form position, helping you achieve more professional page effects in Vue projects.

1. Basic form layout and style optimization

Form layout design in Vue can be implemented through el-form and el-form-item. These components of the Element UI provide simple and easy-to-use interfaces and support various layout tuning. However, using the default layout style alone may cause some common problems, such as the form elements are not neatly typified and the style is not beautiful. Therefore, we can adjust the style according to our needs to make the form look more beautiful and neat.

1.1 Set the layout method of form items

existel-formCan be passedlabel-positionProperties to adjust the position of the form tag. Common values ​​for this property include:

  • "top": Tags are above the form item.
  • "left": The tag is on the left side of the form item.
  • "right": The tag is on the right side of the form item (not commonly used).

For example:

<el-form ref="form" :model="form" label-position="top">
  <el-form-item label="username" prop="userName">
    <el-input v-model="" placeholder="Please enter a username"></el-input>
  </el-form-item>
</el-form>

1.2 Add form container style

By settingel-formThe style can add background color, inner margins and rounded borders, etc., making the entire form area appear more layered. The code is as follows:

<div class="form-container">
  <el-form ref="form" :model="form" label-position="top">
    <!-- Form item configuration -->
  </el-form>
</div>

<style scoped>
.form-container {
  width: 300px;
  padding: 20px;
  background-color: #f7f7f7;
  border-radius: 8px;
  box-shadow: 0 4px 8px rgba(0, 0, 0, 0.1);
}
</style>

Here,paddingIncreased the inner margin of the content area.box-shadowAdded shadow effects, which makes the entire form container feel suspended.

2. Table style optimization and scrollbar configuration

Tables are very common elements in data presentation scenarios. You can pass in Vue projectel-tableAchieve rich table effects, but when the amount of data increases or the layout has special needs, the default style may not meet the project requirements. Next, we will explore how to optimize the table style and add scroll bars to the table content.

2.1 Table width setting and blank on the right

In the table layout, if the table width is not configured properly, there may be an issue of extra blank space on the right side of the table content. We can ensure that the table width occupies the entire container without blanks:

<div class="table-container">
  <el-table :data="tableData" style="width: 100%;" border stripe>
    <el-table-column prop="id" label="ID" width="60"/>
    <el-table-column prop="userId" label="User ID" width="150"/>
    <!-- Other column configurations -->
  </el-table>
</div>

By setting style="width: 100%;", we make sure the table width covers the container. In addition, the maximum width of the table-container can be set to control the overall size of the table so that the table width is adaptable.

2.2 Add scrollbars to the table

When the data volume is large, in order to keep the page layout neat, we can limit the height of the table and add vertical scroll bars. The method is as follows:

<div class="table-scroll-container">
  <el-table :data="tableData" style="width: 100%;" border stripe>
    <el-table-column prop="id" label="ID" width="60"/>
    <el-table-column prop="userId" label="User ID" width="150"/>
    <!-- Other column configurations -->
  </el-table>
</div>

<style scoped>
.table-scroll-container {
  max-height: 400px; /* Set maximum height */
  overflow-y: auto; /* Enable vertical scrolling */
}
</style>

By settingoverflow-y: auto;, When the table content exceeds 400px, the vertical scroll bar will automatically appear.

3. Adjust the overall layout of forms and tables: realize centering and downward movement

In actual development, in order to meet the page design needs, forms or forms may require overall position adjustments in the page. For example, we can display the form or form content vertically and adjustmarginorpaddingAchieve downward movement.

3.1 The form content is centered vertically and moved downward

Move the login box or form down a certain distance, you can set it to the outer container.margin-topaccomplish. Examples are as follows:

<div class="login-container">
  <div class="login-box">
    <!-- Login form content -->
  </div>
</div>

<style scoped>
.login-container {
  display: flex;
  justify-content: center;
  align-items: center;
  height: 100vh; /* Vertical centering */
  margin-top: 50px; /* Move down */
}

.login-box {
  width: 300px;
  padding: 20px;
  background-color: #fff;
  border-radius: 8px;
  box-shadow: 0 4px 8px rgba(0, 0, 0, 0.1);
}
</style>

Set height: 100vh, justify-content: center and align-items: center to allow the form to be centered vertically in the page. At the same time, the margin-top is used to control the distance of the form moving downward relative to the entire viewport.

4. FAQ

4.1 The problem that the table width setting does not take effect

If the table width setting does not take effect, it may be because the table is included in other components, such as the background component. In this case, it is recommended to first confirm whether the parent component has sufficient width, while ensuring that the width of the el-table is set correctly. If it still doesn't work, try adding overflow: hidden to the parent component to remove the excess content.

4.2 Ideas for moving form content downward

When adjusting the form position, if the margin-top setting is directly used does not take effect, check whether there is a parent container that limits the range of form movement. Movement can be achieved by adjusting the position attribute of the parent container and setting top, or smooth displacement using the transform: translateY() method.
