1) Organizando ícones nas redes sociais

 <div class="apresentaçao__links">
                <h2 class="apresentacao_links_subtitulo">Acesse minhas redes:</h2>
            <a class="apresentaçao__links__links" href="https://instagram.com/brittoruth">
                <img src="./Assets-aula2-curso3-html-e-css-main/Assets-aula2-curso3-html-e-css-main/assets/instagram.png" alt="logo instagram">
                Instagram

            <a class="apresentaçao__links__links" href="https://github.com/brittoruht">

    /*background-color: #22D4FD;*/
    display: flex;
    justify-content: center;
   border: 2px solid #22D4FD;

3) Espaçamento entre ícones e textos

 display: flex;
    justify-content: center;
   border: 2px solid #22D4FD;
    gap: 16px;
