адаптивным вышел у меня хедер и тизер?

Для адаптивных дизайнов нужно писать под все разрешения мониторов
/* Smartphones (portrait and landscape) -----------*/
@media only screen
and (min-device-width : 320px)
and (max-device-width : 480px) {
/* Styles */
}

/* Smartphones (landscape) -----------*/
@media only screen
and (min-width : 321px) {
/* Styles */
}

/* Smartphones (portrait) -----------*/
@media only screen
and (max-width : 320px) {
/* Styles */
}

/* iPads (portrait and landscape) -----------*/
@media only screen
and (min-device-width : 768px)
and (max-device-width : 1024px) {
/* Styles */
}

/* iPads (landscape) -----------*/
@media only screen
and (min-device-width : 768px)
and (max-device-width : 1024px)
and (orientation : landscape) {
/* Styles */
}

/* iPads (portrait) -----------*/
@media only screen
and (min-device-width : 768px)
and (max-device-width : 1024px)
and (orientation : portrait) {
/* Styles */
}

/* Desktops and laptops -----------*/
@media only screen
and (min-width : 1224px) {
/* Styles */
}

/* Large screens -----------*/
@media only screen
and (min-width : 1824px) {
/* Styles */
}

/* iPhone 4 -----------*/
@media
only screen and (-webkit-min-device-pixel-ratio : 1.5),
only screen and (min-device-pixel-ratio : 1.5) {
/* Styles */
}

нет.
1) надо прописать в хеде viewport например так meta name="viewport" content="width=device-width, initial-scale=1.0"
2)у тебя нет медиа в css
