Why are my buttons going out of screen in my Ionic app? - css

Question

I have created a simple chat form in Ionic.
Problem: Buttons are going out of screen.
It looks like this this -
My chat.html
<ion-header>
<ion-navbar>
<ion-title>communicationgiven</ion-title>
<button ion-button (click)="close()" style="margin-left: 90%;margin-top: -3%">Close</button>
</ion-navbar>
</ion-header>
<ion-content padding>
<ion-list>
<div>
<p *ngFor="let list of list; let i = index;">
<ion-item>
<!-- <p style="color: #1bb0f4;font-size: 20px;">Tagto {{list.TAG_TO}}</p> -->
<p style="color: #1bb0f4;"> {{list.TAG_FROM}}</p>
<p style="color: #d2dce1;"> {{list.TAG}}</p>
</ion-item>
</p>
</div>
</ion-list>
</ion-content>
<ion-footer class="footer">
<form #com="ngForm" (submit)="onsubmit(com.value)">
<ion-input placeholder="TAG" type="text" name="TAG" ngModel ></ion-input>
<button ion-button type="submit" style="margin-left: 90%;margin-top: -5%;">Submit</button>
</form>
</ion-footer>
I want to know why my buttons are going out of the page; how can I make sure they stay inside the screen, irrespective of the screen size?
What is the best practice here? I am fairly new in CSS.

Answer 1

You have to use below code for left button
<ion-header>
<ion-navbar>
<button ion-button icon-only menuToggle>
<ion-icon name="menu"></ion-icon>
</button>
<ion-title>
Page Title
</ion-title>
<ion-buttons end>
<button ion-button icon-only (click)="openModal()">
<ion-icon name="options"></ion-icon>
</button>
</ion-buttons>
</ion-navbar>
</ion-header>
For footer you can use ion-grid
<ion-footer class="footer">
<form #com="ngForm" (submit)="onsubmit(com.value)">
<ion-grid>
<ion-row>
<ion-col col-9>
<ion-input placeholder="TAG" type="text" name="TAG" ngModel ></ion-input>
</ion-col>
<ion-col col-3>
<button ion-button type="submit">Submit</button>
</ion-col>
</ion-row>
</ion-grid>
</form>
</ion-footer>

Answer 2

you had given style="margin-left: 90% that is margin from left side is 90% so obviously it will go out of screen, try to decrease the value.

Answer 3

It's hard to answer this one as I can't replicate the issue locally with what you've provided.
I'd start by reducing the margin-left: 90% on the button element, see how that goes.
In regard to best practices, an important one is to not use inline styles. That is putting styles in the style html attribute. Instead try using an external style sheet or at least an internal style sheet, see: https://www.w3schools.com/css/css_howto.asp
