Why does this CSS margin-top style not work?

Float left

    float: left;
}

background vom Parent ist transparent?

Parent hat nun auch float left! Background wieder da!

.flexbox
{
    width: 90%;
    margin: 5%;
    background: #dadada;
    float: left;
}

Letztes div nicht mehr float left

        <div class="flexelement-clear">Box 4</div>
        <div class="flexelement">Box 5</div>

.flexelement-clear
{
    background: #ff6600;
    color: #ffffff;
    text-align: center;
    margin: 10px;
    padding: 15px;
    clear: left;
}

STM32Cube ADC

I believe there is a bug in HAL_ADC_ConfigChannel(). Using the STM32g071, with ADC_SCAN_SEQ_FIXED, ADC_EOC_SINGLE_CONV, and NbrOfConversion == 1, when HAL_ADC_ConfigChannel() is called, it OR’s in the new channel number, which is incorrect.
