文本仍然包裹在它的父 div 中 - CSS、React

Question

The question is pretty straight-forward and I have read lots and lots of posts about the same issue, though in my specific case all these solutions are not working because I am probably handling it wrong or making it over-complicated.

Some of the solutions I tried:

• Why is this CSS nowrap not working?
• Let text go through a div
• CSS white-space nowrap not working
• Don't wrap span elements

Most of these posts come to the conclusion that you should use inline-block in combination with white-space: nowrap . Though after numerous trial and error tries, I actually kinda forgot what I did and did not try..

My specific case

I have a React application in which I want to display an hours-bar . This bar has a (sort-of) table layout but just with 1 row . The bar consists out of 15 cells ( div's ).

The problem

Each cell should have a specific text above it when a certain condition is met. So for example, I want to show a text value on the starting cell div, and the ending cell div and then each 5th cell again. It should look something like this:

I figured I could achieve this by making a 'Time' row inside the body of the time bar, however when I add it as a separate row, then the times / text will never be above the correct cells when the bar has multiple lines on the screen, you would then get something like this:

So my next idea was to make 2 separate div's inside the row where 1 div (the top div) functions as the header and the second div functions as the actual bar:

<TimeColumnBody>        
    <TimeColumnHeader>
        {(() => {
            if (item.showtime === true)
            {
                return <Test>{item.name}</Test>
            }
        })()}
    </TimeColumnHeader>
    <TimeColumn
        key={item.key} 
        name={item.name}
    >
    </TimeColumn>
</TimeColumnBody>

The above html get's rendered on each separate cell (time-step), so with the above example that would be 15 times (8:00 to 11:30 with steps of 15 minutes).

The objects TimeColumnBody , TimeColumnHeader and TimeColumn are created inside the react file and they are simple custom div elements with styling (using styled-components ) :

const TimeColumnBody = styled.div`
    float: left;
    width: 100%;
    height: 100%;
    @media only screen and (min-width: 768px) {
        width: ${props => (props.span ? props.span / 44 * 100 : "2.27")}%;
        height: 100%;
    }
`;

const TimeColumnHeader = styled.div`
    display: flex;
    align-items: flex-end;
    height: 50%;
    background-color: blue;
    color: white;
    white-space: nowrap;
`;

const TimeColumn = styled.div`
    height: 50%;
    background-color: red;
`;

The creating of the entire table / time-bar happens in the React render part:

render() {
        return (
                <TimeContainer>
                    <TimeRow>
                        {this.renderTimeTable()}
                    </TimeRow>
                </TimeContainer>
        );      
    }

The renderTimeTable function is the part where the cells are being created ( TimeColumnBody , TimeColumnHeader , TimeColumn elements).

The text inside the TimeColumnHeader div remains wrapped inside the div even with the white-space: nowrap; property:

I tried adding the white-space: nowrap; property to the TimeColumn div with no effect, then I added the display: inline-block property with no effect, then I tried adding it to some parent div's but also without result.

The entire styling looks (currently) as follows (style added inline for easier reading):

<div class="App" style="text-align: center; height: 100%; overflow: auto;">
    <div class="Nav-LeftPane" style="width: 15%; height: 100%; position: fixed; box-sizing: border-box; overflow-y: auto; float: left;">...</div>
    <div class="content" style="width: 85%; height: 100%; text-align: center; overflow: hidden; float: right;">
        <div class="content-timebar" style="padding-left: 1%; padding-right: 1%; padding-top: 3%; height: 100%;">
            <!-- The actual Time Bar : --> 
            <div class="TimeContainer" style="width: 100%; height: 10%;">
                <div class="TimeRow" style="height: 100%;"> <!-- This div also has some :after logic: .TimeRow::after { content: ""; clear: both; display: table; } -->
                    <!-- the cell part which gets generated 15 times -->
                    <div class="TimeColumnBody" style="width: 2.222%; height: 100%; float: left;">
                        <div class="TimeColumnHeader" style="display: flex; align-items: flex-end; height: 50%; background-color: blue; color: white; white-space: nowrap;">
                            08:00
                        </div>
                        <div class="TimeColumn" style="height: 50%; background-color: red;"></div>
                    </div>
                </div>
            </div>

        </div>
    </div>
</div>

I am now out of ideas and hope someone has a (better) solution to acheive this.

Answer 1

The problem initially appears to be related to overflow or wrapping, but it is actually a z-index issue - because you are floating .TimeColumnBody left, each subsequent element has a higher z-index than the last and thus overlaps the previous item. I was able to fix this simply by adding a span to the first time with:

.TimeColumnHeader span {
   position: absolute;
}
