俺はこうやってしてるけど履歴出るよ
てかSearchWPのボタンを左に寄せたいんだけどどこ弄ればいいの？
全部のpx弄ってみたけど移動しないよ…

/* ::::: SearchWP のハイライトボタンと検索バーを一体化 ::::: */
#search-container + #searchwp-highlight-container > #searchwp-highlight-button {
-moz-appearance: none !important;
border: 0 !important;
background: transparent !important;
box-shadow: none !important;
margin: 4px 32px 4px -50px !important;
padding: 0 !important;
position: fixed !important;
z-index: 1 !important;
}
#searchbar .textbox-input-box {
margin-right: 24px !important;
}

.searchbar-textbox{margin-right: 5px !important;}
.searchbar-textbox .textbox-input-box{margin-right: 30px !important;}
#searchwp-highlight-button{margin-right: 30px !important;}
