var
Variablendeklarationen werden immer ausgeführt bevor Programmcode ausgeführt wird, egal wo sie im Programmcode vorkommen. Der Gültigkeitsbereich einer Variablendeklaration mit var ist der aktuelle Kontext. Dieser ist der Kontext der umschließenden Funktion oder für Deklarationen außerhalb von Funktionen der globale Kontext.

let
let ermöglicht es Variablen zu deklarieren, deren Gültigkeitsbereich auf den Block, den Befehl oder den Ausdruck beschränkt ist, in dem sie deklariert sind. Der Unterschied zum var Schlüsselwort ist, dass der Gültigkeitsbereich auf Blöcke und nicht auf Funktionen bzw. Global beschränkt ist.

Why does this CSS margin-top style not work?

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>

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.
