HTML element height not at 100% using Blazor Server

I’m using Blazor Server .NET 6.0 with Syncfusion, and I have a problem with my HTML/CSS. As you can see here, for some reason, my body and even my content div don’t go 100% height, only if I change it to 100vh, which I don’t really want. The reason for that is that with the top padding, I’m getting a scrollbar on the right.

MainLayout.razor.css

.page {
    position: relative;
    display: flex;
    flex-direction: column;
    height: 100%;
}


.topnav {
    height: 3.5rem;
    background-color: rgba(0,0,0,0.4);
}

.navbar-toggler {
    background-color: #05163C;
}

.navbar-dark .navbar-toggler {
    color: transparent;
    border-color: transparent;
}

.navbar-brand {
    font-size: 1.1rem;
    margin-right: 24px;
}

@media (min-width: 641px) {
    .navbar-toggler {
        display: block;
    }

    .collapse {
        /* Never collapse the sidebar for wide screens */
        display: block;
    }
}

.main {
    flex: 1;
}

.sidebar {
    background-image: linear-gradient(180deg, rgb(64, 120, 155) 0%, #ffffff 95%);
}

.top-row {
    background-color: #fff;
    border-bottom: 1px solid;
    border-bottom-color: #E2E7EE;
    box-shadow: 0px 1px 4px 0px rgba(0,0,0,0.08);
    justify-content: flex-end;
    height: 3.5rem;
    display: flex;
}

    .top-row ::deep a, .top-row .btn-link {
        white-space: nowrap;
        margin-left: 1.5rem;
    }

    .top-row a:first-child {
        overflow: hidden;
        text-overflow: ellipsis;
    }

@media (max-width: 640.98px) {
    .top-row:not(.auth) {
        display: none;
    }

    .top-row.auth {
        justify-content: space-between;
    }

    .top-row a, .top-row .btn-link {
        margin-left: 0;
    }
}

@media (min-width: 641px) {
    .page {
        flex-direction: row;
    }

    .sidebar {
        width: 250px;
        height: 100vh;
        position: sticky;
        top: 0;
    }

    .top-row {
        position: sticky;
        top: 0;
        z-index: 1;
    }

    }

    .sidebar .collapse {
        /* Never collapse the sidebar for wide screens */
        display: block;
    }
}

This is the part of the MainLayout.razor that I changed; the rest should be the default of Syncfusion.


<div class="main">
    <header class="top-row px-4" style="z-index: 1111; padding-top: 0; display: flex; justify-content: space-between; align-items: center;">
        <div style="display: flex; align-items: center;">
            <img src="/Logo.png" width="40" height="40" alt="Logo" style="margin-right: 0.7rem;">
            <NavLink class="nav-link-o" href="" Match="NavLinkMatch.All">
                Startseite
            </NavLink>
            <div style="margin-left: 1.5rem; width: 1px; height: 25px;color: rgba(0,0,0,0.4);">|</div>
            <NavLink class="nav-link-o" href="#">
                Aufgaben
            </NavLink>
            <NavLink class="nav-link-o" href="esg">
                ESG Umfrage
            </NavLink>
            <NavLink class="nav-link-o" href="ltf">
                LookThroughFonds
            </NavLink>
        </div>
        <div>
            <LoginDisplay />
        </div>
    </header>

    <div class="content px-4">
        @Body
    </div>
</div>

I tried to make the height 100%, which did nothing; only 100vh seemed to work.

    Maybe you could add a box-sizing:border-box on all elements

    * {
   box-sizing: border-box;
}

    You’ll need to define all other nesting containers with 100% in order for it to be working.

    With the code you’ve provided me you can achieve this with

    html, body, .main {
 height: 100%;
}

    But maybe 100dvh may already solve your issue.
