我正在为博客准备布局,需要或多或少地制作幻灯片,如下所示:

我已经能够通过CSS做很多事了,但我遇到了问题!图像仅在鼠标悬停在div上时激活,但是当我将鼠标悬停在图像链接上时,我需要激活图像,或者更好地将图像着色。

有人可以帮我解决这个问题吗?

我不知道我是通过CSS还是仅通过JavaScript来做到这一点。我甚至尝试通过JavaScript做更多事情,但对此并不了解。

您需要在图像和文本的父级上使用伪类:hover。当您将鼠标悬停在该元素的任何子元素上时,这将改变图像的不透明度。

更改此

.img-box-feature:hover{opacity:1;}

到这个

[class*="box-"]:hover .img-box-feature{opacity:1;}

See updated Bootply

另外,我建议您将课程从box-umbox-doisbox-tres更改为box。然后,您可以使用.box:nth-child().box:nth-of-type()定位特定的目标。

如果您更改此行:

.img-box-feature:hover {
  opacity:1;
}

到此:

.img-box-feature:hover,
.img-box-feature.hover{
  opacity:1;
}

您可以使用jQuery切换到新类:

$('.over-text-feature h1 a').on('mouseenter mouseleave', function(e) {
  $(this).closest('[class^="col-"]').find('.img-box-feature').toggleClass('hover');
})

试用webkit filters

e.g。 .img-box-feature2:悬停{-webkit-filter:invert(100%);}

您还可以使用对比度(%),亮度(十进制),模糊(px)或棕褐色(%)

当我将图像悬停在文本上时,如果您希望图像激活 ,或者将鼠标悬停在文本上时,我仍然不清楚。我也想知道你是否希望所有图像只能一个

如果您想要 all ,只有 的图像在悬停文本时才会变为活动状态,您可以将文本元素移动为.section-slider的第一个子元素,并使用CSS兄弟选择器:~

像这样:

<section class="section-slider">
  <div class="over-text-feature">
    <h1><a href="#">Lorem Ipsum é simplesmente uma simulação de texto da indústria tipográfica e de impressos</a></h1>
    <p>Lorem Ipsum é simplesmente uma simulação de texto da indústria tipográfica e de impressos</p>
