刪除wordpress（HTML）中嵌入的youtube視頻之前的空白區域？

Question

我試圖在我的WordPress頁面的「文本」面上嵌入Youtube視頻之前刪除空白區域（空白處）。

網頁是： vicash.com.au/sustainability

HTML：

[/vc_column_text][/vc_column][/vc_row][vc_row type="full_width_background" full_screen_row_position="middle" bg_color="#ffffff" scene_position="center" text_color="dark" text_align="left" class="narrow-layout xtra-large-panel-spacing-bottom" overlay_strength="0.3"][vc_column column_padding="no-extra-padding" column_padding_position="all" background_color_opacity="1" background_hover_color_opacity="1" column_shadow="none" width="1/1" tablet_text_alignment="default" phone_text_alignment="default" column_border_width="none" column_border_style="solid"][vc_row_inner column_margin="default" text_align="left"][vc_column_inner column_padding="no-extra-padding" column_padding_position="all" background_color_opacity="1" width="1/4" column_border_width="none" column_border_style="solid"][image_with_animation image_url="282" alignment="center" animation="Fade In" box_shadow="none" max_width="100%"][/vc_column_inner][vc_column_inner column_padding="no-extra-padding" column_padding_position="all" background_color_opacity="1" width="1/4" column_border_width="none" column_border_style="solid"][image_with_animation image_url="283" alignment="center" animation="Fade In" box_shadow="none" max_width="100%"][/vc_column_inner][vc_column_inner column_padding="no-extra-padding" column_padding_position="all" background_color_opacity="1" width="1/4" column_border_width="none" column_border_style="solid"][image_with_animation image_url="7311" alignment="center" animation="Fade In" box_shadow="none" max_width="100%"][/vc_column_inner][vc_column_inner column_padding="no-extra-padding" column_padding_position="all" background_color_opacity="1" width="1/4" column_border_width="none" column_border_style="solid"][image_with_animation image_url="284" alignment="center" animation="Fade In" box_shadow="none" max_width="100%"][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row type="full_width_background" full_screen_row_position="middle" bg_color="#ffffff" scene_position="center" text_color="dark" text_align="left" class="narrow-layout xtra-large-panel-spacing-bottom xtra-large-panel-spacing-top" overlay_strength="0.3"][vc_column column_padding="no-extra-padding" column_padding_position="all" background_color_opacity="1" background_hover_color_opacity="1" column_shadow="none" width="1/1" tablet_text_alignment="default" phone_text_alignment="default" column_border_width="none" column_border_style="solid"][vc_column_text] <iframe src="https://www.youtube.com/embed/XWcuuhqURT0?list=FLN3Wt2NBx_dlKyf_i8ALtzA" width="560" height="315" frameborder="0" allowfullscreen="allowfullscreen"></iframe>

我讀過的其他問題，人們紛紛表示加：

body { 
    margin: 0; 
} 

但我在哪裏添加？當我嘗試它不起作用。

Answer 1

在WordPress管理面板中去→外觀→自定義→附加CSS，你就可以在這裏插入任何CSS代碼。

此外，切換到HTML模式的任何頁面上，然後確保包裹CSS與<style>標籤，就像這樣：

<style> 
/* CSS goes here. */ 
body { 
    margin: 0; 
} 
</style>
