Question

我有一个我似乎找不到的小虫子。在我的代码片段中，您可以看到无论何时将鼠标悬停在图像上，不透明和图像比例，以及图像上方都会出现一个框。这是完美的，但我的问题是，只要您将鼠标悬停在其下方的文本上，悬停效果就会发生在图像上。

我似乎无法弄清楚只有当鼠标悬停在图像上时悬停效果才会发生。

任何建议都将不胜感激。

#include <algorithm>        // std::swap
#include <iostream>         // ...
#include <utility>          // std::move
#include <vector>           // std::vector    
using namespace std;

class Item
{
private:
    int id_;

    Item( Item const& ) = delete;
    auto operator=( Item const& ) -> Item& = delete;

public:
    auto operator=( Item&& other ) -> Item&
    { id_ = other.id_; other.id_ = 0; return *this; }

    ~Item()
    { if( id_ != 0 ) { wcout << "Destroyed #" << id_ << ".\n"; } }

    Item( int id )
        : id_( id )
    { wcout << "Created #" << id_ << ".\n"; }

    Item( Item&& other )
        : id_( other.id_ )
    { other.id_ = 0; }
};

auto main() -> int
{
    vector<Item> v;
    for( int i = 1; i <= 7; ++i ) { v.push_back( Item( i ) ); }

    wcout << "capacity with 7 items: " << v.capacity() << "\n";
    v.erase( v.begin() + 2, v.end() );
    wcout << "capacity with " << v.size() << " items: " << v.capacity() << "\n";
    // Forcibly reduce the capacity. Can't just copy since Item isn't copyable:
    {
        vector<Item> copy;
        for( Item& o : v ) { copy.push_back( move( o ) ); }     // Move items over.
        swap( v, copy );
    }
    wcout << "Capacity after forced reduce: " << v.capacity() << endl;
}

和

.home-img-block:hover .overlay

用

替换它们

.home-img-block:hover img

否则当你将鼠标悬停在整个容器上而不是只悬停img时，你就会触发。

悬停事件发生在我想要的区域之外
