Inner html div doesn't behave width the expected width

Question

I'm building a personal page for myself, using react and libraries such as styled components, for react. But when I was building the header section, all of a sudden the content started not to behave as expected, with the inner div not matching its parent's width anymore. Here goes the codes:

import styled from 'styled-components'

export const SectionContainer = styled.section`
    display: flex;
    flex-direction: column;
    justify-content: center;
    align-items: center;
    height: 600px;
    overflow: hidden;
`

import styled from 'styled-components'
import { SectionContainer } from '../components/SectionContainer'

const Container = styled.div`
    @import url('https://fonts.googleapis.com/css2?family=Roboto:wght@300&display=swap');

    @media (min-width: 501px) {
        img {
            width: 500px;
            height: 550px;
        }
    }

    @media (max-width: 500px) {
        img {
            width: 70%
            min-width: 300px;
            height: 70%
        }
    }

    text-align: center;
    box-shadow: rgba(0, 0, 0, 0.35) 0px 5px 15px inset;
    overflow: hidden;

    h1 {
        font-size: 2.8rem;
        padding-top: 50px;
        padding-left: 10px;
    }

    h2 {
        font-family: 'Roboto';
        font-size: 1rem;
        padding: 0 10px;
    }

`

const Header = props => {
    return (
        <SectionContainer>
            <Container className='header'>
                    <h1>Eduardo Soares Dutra</h1>
                    <h2>Estudante de Ciência da Computação | Desenvolvedor front-end</h2>
                    <img src="src\media\Code typing-bro.svg" alt="Front-end Dev" />
            </Container>
        </SectionContainer>
    )
}

export default Header

Answer 1

From what I can see here it looks like you have specified that for any devices with a min-width of 501px or more the width of the Container is set to 500px.

@media (min-width: 501px) { img { width: 500px; height: 550px; } }

So that would override the parent container based on my understanding.
