I have checked the code several times and apparently I did not find any errors, it follows the html and css part of this class:
HTML:
main .main-pagina .services-principal {display: table;background: #eee;margin-bottom: 100px}
main .main-pagina .services-principal .services {float: left;width: 49%;background: transparent;box-sizing: border-box;background: #eee;margin: 0;padding: 5px}
main .main-pagina .services-principal .services .services-bloco {padding: 20px 5px;display: table}
main .main-pagina .services-principal .services .services-bloco img {float: left;}
