小编Tum*_*hir的帖子

我目前有以下图片列表:

<div id='images'>
        <img src="images/placeholders/ph.jpeg" alt="Content missing"/>
        <img src="images/placeholders/ph1.jpg" alt="Content missing"/>
        <img src="images/placeholders/ph2.jpg" alt="Content missing"/>
        <img src="images/placeholders/ph3.jpg" alt="Content missing"/>
    </div>

这些图像循环并放置在彼此的顶部,淡入和淡出.图像具有固定的高度,但是具有可变的宽度.该宽度在左侧和右侧可变.

例如bannerimage:http://i.imgur.com/6zrWBD9.jpg

在缩放浏览器窗口后我想要的是:http: //i.imgur.com/figgCuJ.jpg

高度是固定的,在浏览器窗口缩放期间,两侧都被切断了相等的量.我希望有人能帮助我解决这个问题.我不知道用什么代码来调整我想要它的方式.

提前致谢!

我的类和存储库的结构：

public class Group{
    //fields
}

public class User{
    public UserRole Role {get;set;}
}

public abstract class UserRole{
    //fields
}

public class PersonUserRole:UserRole{
    public Group Group {get;set;}
}

public class ManagerUserRole:UserRole{
    public IList<Group> Groups {get;set;}
}

我遇到问题的示例：

public class UserRepository:IUserRepository{
    private readonly ApplicationDbContext _dbContext;
    private readonly DbSet<User> _users;

    public UserRepository(ApplicationDbContext dbcontext)
    {
        _dbContext = dbcontext;
        _users = _dbContext.DomainUsers;
    }

    public User GetBy(int id)
        {
            User type = _users.Include(u => u.Role)
                              .SingleOrDefault(c => c.UserId == id);
            if (typeof(PersonUserRole) == type.Role.GetType())
            { …
