所有分辨率下的位置圖像都相似

Question

我在這裏有點複雜的情況（至少對我來說很複雜）。附上小提琴，以顯示我是如何努力完成這一點。

我想將講話泡泡放在黃色圖像黑線的中央。 （在小提琴中顯示）。

另外，當我走到較小的設備時，文本會在對話框下面流動。 （你可以重新調整窗口大小並看看）

所有這些都必須顯示在100 vh高度的含義，用戶不需要滾動查看氣泡以及圖像。

Answer 1

嘗試此代碼：

.bubble { 
 
    position: relative; 
 
    z-index: 1; 
 
    /*width: 80%;*/ 
 
    height: auto; 
 
    /* margin-left:12.5%;*/ 
 
    padding: 5%; 
 
    background: #2e3c6f; 
 
    -webkit-border-radius: 15px; 
 
    -moz-border-radius: 15px; 
 
    border-radius: 15px; 
 
    color:darkgrey; 
 
} 
 

 
.bubble:after { 
 
    content: ''; 
 
    position: absolute; 
 
    border-style: solid; 
 
    border-width: 32px 21px 0; 
 
    border-color: #2e3c6f transparent; 
 
    display: block; 
 
    width: 0; 
 
    z-index: 1; 
 
    margin-left: -10.5px; 
 
    bottom: -32px; 
 
    left: 50%; 
 
} 
 

 
.about_bg { 
 
    width: 100%; 
 
    height: auto; 
 
} 
 

 
#about_container { 
 
    height: 100vh; 
 
    margin-top: 2.5%; 
 
} 
 

 
#row_about_1 { 
 
    height: 80vh; 
 
} 
 

 
#row_about_2 { 
 
    height: 20vh; 
 
}

解決方案：

1）要設置氣泡箭頭中心： - >添加位置ABSOL ute和左值50％，然後增加餘量10.5％（這是箭頭的半寬度）

2）重疊內容： - >設置氣泡高度自動（以前是80％），現在當你將調整瀏覽器大小不會受到干擾。

Answer 2

您可能需要更流暢的解決方案，但通過媒體查詢，您可以在較大的屏幕上從底部調整圖像大小和位置氣泡。只需添加一個步驟，例如。在屏幕上> 1200px。 爲了避免溢出我會保持容器的最小高度...

.about-container { 
 
\t height: 100vh; 
 
\t min-height: 580px; 
 
} 
 

 
.about-container .wrap { 
 
\t position: relative; 
 
\t height: 100%; 
 
} 
 

 
.bubble { 
 
\t background: #2e3c6f; 
 
\t color: #fff; 
 
\t position: absolute !important; 
 
\t bottom: 150px; 
 
\t left: 0; 
 
\t padding: 30px; 
 
\t border-radius: 15px; 
 
\t z-index: 1; 
 
} 
 

 
.bubble:after { 
 
\t position: absolute; 
 
\t content: ''; 
 
\t top: 100%; 
 
\t left: 50%; 
 
\t height: 0; 
 
\t width: 0; 
 
\t border: solid transparent; 
 
\t border-top-color: #2e3c6f; 
 
\t border-width: 30px; 
 
\t margin-left: -30px; 
 
} 
 

 
p:last-child { 
 
\t margin-bottom: 0; 
 
} 
 

 
.about-img { 
 
\t position: absolute; 
 
\t bottom: 0; 
 
\t left: 0; 
 
\t right: 0; 
 
\t margin: 0 auto; 
 
\t max-width: 320px; 
 
\t height: auto; 
 
}
