浮动标签和占位符重叠 [英] floating label and placeholder overlapping
本文介绍了浮动标签和占位符重叠的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
<div class="form-group form-default form-spacing">
<input class="form-control" placeholder="Name" type="text" required>
<span class="form-bar"></span>
<label class="float-label">Name</label>
</div>
这是CSS,
.form-material {
.form-group {
position: relative;
&.form-static-label .form-control {
~.float-label {
top: -14px;
}
}
}
.form-control {
&:focus {
border-color: transparent;
outline: none;
box-shadow: none;
}
&:focus,
&:valid {
~.float-label {
top: -14px;
}
}
}
如果我专注于文本字段,则效果很好. 但是当没有焦点时,它就会重叠. asdasd dasd dasdsad广告asd das dasd asd a das
if i focus on text field it works fine. but when there is no focus it's overlapping. asdasd dasd dasdsad ad asd das dasd asd a das
推荐答案
请尝试以下操作:
npm install-保存@ angular/material @ angular/cdk @ angular/animations
npm install --save @angular/material @angular/cdk @angular/animations
在app.module.ts中:
import {MatFormFieldModule} from '@angular/material/form-field';
html:
<form [formGroup]="addressForm" novalidate (ngSubmit)="onSubmit()">
<mat-card class="shipping-card">
<mat-card-header>
<mat-card-title>Address, Neighborhood or ZIP</mat-card-title>
</mat-card-header>
<mat-card-content>
<div *ngIf="hasUnitNumber">
<div class="col">
<mat-form-field class="full-width">
<textarea matInput placeholder="first Name" formControlName="firstName"></textarea>
</mat-form-field>
</div>
</div>
</mat-card-content>
<mat-card-actions>
<button mat-raised-button color="primary" type="submit">Submit</button>
</mat-card-actions>
</mat-card>
</form>
CSS:
.full-width {
width: 100%;
}
.shipping-card {
min-width: 120px;
max-width: 620px;
margin: 20px auto;
}
.mat-radio-button {
display: block;
margin: 5px 0;
}
.row {
display: flex;
flex-direction: row;
}
.col {
flex: 1;
margin-right: 20px;
}
.col:last-child {
margin-right: 0;
}
打字稿组件:
export class MyFormComponent {
addressForm = this.fb.group({
firstName: [null, Validators.required],
});
hasUnitNumber = false;
constructor(private fb: FormBuilder) {}
onSubmit() {
alert('Thanks!');
}
