首先,我是HTML和CSS的入门者。话虽这么说,我在网站的一部分中有这个JS Fiddle:https://jsfiddle.net/rharrison2641/sb3rzm9t/2/
码。)
HTML:
<section class="FutureGoals">
<div class="BlizzBox">
<div class="Blizzard1">
<img alt="BlizzPop" src="https://s8.postimg.cc/5avnnvurp/Blizz_Pop.png" class="BlizzPop">
</div>
</div>
</section>
CSS:
.FutureGoals {
height: 100vh;
overflow: hidden;
}
.BlizzBox {
height: 100vh;
overflow: hidden;
}
.Blizzard1 {
background: url(https://s8.postimg.cc/g96x696k3/Blizzard.jpg);
background-repeat: no-repeat;
background-position: 75%;
background-attachment: fixed;
height: 100%;
width: 100%;
transition: all .5s ease;
-moz-transition: all .5s ease;
-ms-transition: all .5s ease;
-webkit-transition: all .5s ease;
-o-transition: all .5s ease;
webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
}
.Blizzard1:hover {
-webkit-filter: brightness(50%);
-moz-transform: scale(1.1);
-webkit-transform: scale(1.1);
-o-transform: scale(1.1);
-ms-transform: scale(1.1);
transform: scale(1.1);
-ms-filter: "progid:DXImageTransform.Microsoft.Matrix(M11=1.5, M12=0, M21=0, M22=1.5, SizingMethod='auto expand')";
filter: progid:DXImageTransform.Microsoft.Matrix(M11=1.5, M12=0, M21=0, M22=1.5, SizingMethod='auto expand');
}
.BlizzPop {
position: relative;
height: auto;
width: 30%;
left: 25%;
top: 9%;
z-index: 1;
transition: all .7s ease;
-moz-transition: all .7s ease;
-ms-transition: all .7s ease;
-webkit-transition: all .7s ease;
-o-transition: all .7s ease;
}
.Blizzard1:hover .BlizzPop {
z-index: 1;
-moz-transform: scale(1.5);
-webkit-transform: scale(1.5);
-o-transform: scale(1.5);
-ms-transform: scale(1.5);
transform: scale(1.5);
-ms-filter: "progid:DXImageTransform.Microsoft.Matrix(M11=1.5, M12=0, M21=0, M22=1.5, SizingMethod='auto expand')";
filter: progid:DXImageTransform.Microsoft.Matrix(M11=1.5, M12=0, M21=0, M22=1.5, SizingMethod='auto expand');
}
本质上,我要执行的操作是使背景图像Blizzard.jpg变暗,但使Blizzard.png徽标不变暗并保持其白色。就目前而言,一切正常,但徽标变暗为淡灰色。我尝试过将图像与背景图像放置在div之外,但这只会导致窗口大小调整极大地扭曲。有人可以为此提出建议吗?我已经尝试了好几天,所以任何解决方案或帮助将不胜感激。
您可以将rgba()
渐变悬停在上background-image
以使其变暗。
background:
linear-gradient(0deg, rgba(0, 0, 0, 0.5), rgba(0, 0, 0, 0.5)),/* the gradient on top, adjust color and opacity to your taste */

或设置inset
box-shadow
还具有rgba()
颜色(过渡也是有效的上箱阴影)
box-shadow:inset 0 0 0 150vw rgba(0,0,0,0.5);/* hudge without blur to cover the whole container */
