与WordPress无关,但该行是通过.qt-caption::after
在scss文件中,_typography.scss
查找:
.qt-caption {
padding: 0.33em 0 0.7em 0;
margin: 0 0 0.5em 0;
position: relative;
&::after {
display: block;
position: absolute;
width: 100%;
height: 2px;
content: " ";
background: rgba(150,150,150,0.3);
bottom: 0;
}
}
或者移除
::after
阻止,或将其设置为
display: none;
相反
