<p> тег css не применяется и <div>неправильно размещен внизу

Question

Мне удалось почти завершить работу, на которую я смотрел, но остается какое-то странное поведение, которое я не могу объяснить.

вот картина того, что я сделал:

and what I expect:

There is few difference that I am not able to fix.

• The text below the credits part is not using the proper size font but it's defined in the css but it strangely the font size is applied when hover..

• The 3 tiles must be also aligned vertically

• The "button + Subscribe" text must be always at the bottom but when hover it moves

Here is the code of the tile itself:

import React from 'react';
import { Button } from 'react-bootstrap';
import TextContents from '../../assets/translations/TextContents';

import './PriceCard.css';

class PriceCard extends React.Component {  

    render() {

        let savingMessage;
        if(this.props.buttontext === TextContents.BuyCreditsBtn){
            savingMessage = {TextContents.SubscribeAndSave} {this.props.percent}{TextContents.Percent}
        }

        return(
              {this.props.price}   {this.props.credits} {TextContents.Credits}  {this.props.desc}  {this.props.buttontext}  {saveMessage}   ); }} экспорт PriceCard по умолчанию; 

и css:

.price-card-container {
    width: 300px;
    height: 420px;
    background-color: white;
    box-shadow: 0px 8px 18px 0 rgba(0,0,0,0.14);
    border-radius: 30px;
    position: relative;
    margin-left: 10px;
    margin-right: 10px;
    transition: 0.5s;
}

.price-card-container:hover {

На моей веб-странице используется плитка с ценовой картой, как показано ниже:

                </div>

        return (

export default HowItWorks;

/* tablet, ipad  version (change font-size here if needed)*/
@media (min-width: 768px) and (max-width: 1024px){

    .hiw-container {
        margin-left: auto;
        margin-right: auto;
        margin-bottom:5rem;
        width: 50%;
    }

}

/* mobile version (change font-size here if needed)*/
@media (max-width: 600px) {

    .hiw-container {

        margin-right: auto;
        margin-bottom:5rem;
        width: 70%;
    }

}

Есть идеи? Спасибо
