merhaba hocalarım,

Header kodları üzerinde ne kadar oynama yapsam ve ne kadar ctrl + F5 yapsam da yüksekliği düşüremedim. Kullandığım tema Yirmi Ondokuz. https://tr.wordpress.org/themes/twentynineteen/

İstediğim, bu yüksekliği yarıya düşürmek.

Kodlar ise şu şekilde:

## Header
--------------------------------------------------------------*/
.site-header {
padding: 1em;
}

.site-header.featured-image {
display: flex;
flex-direction: column;
justify-content: space-between;
min-height: 90vh;
}

.site-header.featured-image .site-branding-container {
margin-bottom: auto;
}

@media only screen and (min-width: 768px) {
.site-header {
margin: 0;
padding: 3rem 0;
}
.site-header.featured-image {
min-height: 100vh;
margin-bottom: 3rem;
}
}

.site-branding {
color: #767676;
-webkit-hyphens: auto;
-moz-hyphens: auto;
-ms-hyphens: auto;
hyphens: auto;
position: relative;
word-wrap: break-word;
}

@media only screen and (min-width: 768px) {
.site-branding {
margin: 0 calc(10% + 60px);
}
}

.site-logo {
position: relative;
z-index: 999;
margin-bottom: calc(.66 * 1rem);
}

@media only screen and (min-width: 768px) {
.site-logo {
margin-bottom: 0;
position: absolute;
right: calc(100% + (1.25 * 1rem));
top: 4px;
z-index: 999;
}
}

.site-logo .custom-logo-link {
border-radius: 100%;
box-sizing: content-box;
box-shadow: 0 0 0 0 rgba(0, 0, 0, 0);
display: block;

}

.site-logo .custom-logo-link .custom-logo {
min-height: inherit;
}

.site-logo .custom-logo-link:hover, .site-logo .custom-logo-link:active, .site-logo .custom-logo-link:focus {
box-shadow: 0 0 0 2px black;
}

@media only screen and (min-width: 768px) {
.site-logo .custom-logo-link {

height: 64px;
}
}

.site-title {
margin: auto;
display: inline;
color: #111;
/* When there is no description set, make sure navigation appears below title. */
}

.site-title a {
color: #111;
}

.site-title a:link, .site-title a:visited {
color: #111;
}

.site-title a:hover {
color: #4a4a4a;
}

.featured-image .site-title {
margin: 0;
}

@media only screen and (min-width: 768px) {
.featured-image .site-title {
display: inline-block;
}
}

.site-title + .main-navigation {
display: block;
}

@media only screen and (min-width: 768px) {
.site-title {
display: inline;
}
}

.site-title:not(:empty) + .site-description:not(:empty):before {
content: "2014";
margin: 0 .2em;
}

.site-description {
display: inline;
color: #767676;
font-weight: normal;
margin: 0;
}
