Ottenere l'altezza dell'elemento del blocco in linea per riempire il genitore

Question

Ho un contenitore con due elementi. Uno di questi elementi è un elemento select, quindi ho bisogno di impostare l'attributo size tramite HTML. Voglio l'altro elemento nel contenitore per allungare la sua altezza per adattarsi al contenitore. Non riesco a capirlo. Non voglio impostare in modo esplicito l'altezza del contenitore perché non conosco la dimensione della casella di selezione.

.container { 
 
    padding: 5px; 
 
    border: 1px solid black; 
 
} 
 

 
.container .column { 
 
    display: inline-block; 
 
    width: 40%; 
 
    background-color: #AAA; 
 
    padding: 5px; 
 
    margin: 5px; 
 
    vertical-align: top; 
 
    height: 100%; 
 
} 
 

 
select { 
 
    width: 100%; 
 
}

<div class="container"> 
 
    <div class="column">Stretch to fill?</div> 
 
    <div class="column"> 
 
    <select size="15"> 
 
      <option>Option 1</option> 
 
      <option>Option 2</option> 
 
     </select> 
 
    </div> 
 
    <div>

Answer 1

Se table-cell è un'opzione, ecco un modo per farlo:

.container { 
 
    display: table; 
 
    width: 100%; 
 
    padding: 5px; 
 
    border: 1px solid black; 
 
} 
 

 
.container .column { 
 
    display: table-cell; 
 
    width: 40%; 
 
    background-color: #AAA; 
 
    padding: 5px; 
 
    border: 5px solid white; 
 
    vertical-align: top; 
 
    height: 100%; 
 
} 
 

 
select { 
 
    width: 100%; 
 
}

<div class="container"> 
 
    <div class="column">Stretch to fill?</div> 
 
    <div class="column"> 
 
    <select size="15"> 
 
      <option>Option 1</option> 
 
      <option>Option 2</option> 
 
     </select> 
 
    </div> 
 
    <div>

Answer 2

Se ho capito quello che stai dicendo, si trovano ad affrontare il problema 100% height columns. Mi dispiace dirti che non esiste una soluzione reale ma "hack".

Here è possibile trovare alcuni di questi soluzioni alternative. Mi piace usare l'unico vero metodo di layout.

A proposito, questo sta pensando che non si desidera utilizzare le proprietà delle colonne css3 sperimentali.

Un esempio in cui avevo bisogno di un elemento pseudo anche:

.cf:before, 
 
.cf:after { 
 
\t content: " "; /* 1 */ 
 
\t display: table; /* 2 */ 
 
} 
 

 
.cf:after { 
 
\t clear: both; 
 
} 
 

 

 
*, *:before, *:after { 
 
\t -moz-box-sizing: border-box; -webkit-box-sizing: border-box; box-sizing: border-box; 
 
} 
 

 
.faux-columns { 
 
\t width: 80%; 
 
\t margin:3em auto; 
 
\t background-image: -webkit-linear-gradient(left, #f2f7fa 25%, #fff 75%); 
 
\t background-image: -moz-linear-gradient(left, #f2f7fa 25%, #fff 75%); 
 
\t background-image: -o-linear-gradient(left, #f2f7fa 25%, #fff 75%); 
 
\t background-image: linear-gradient(left, #f2f7fa 25%, #fff 75%); 
 
\t background: -webkit-gradient(linear, left top, right top, color-stop(0%,#f2f7fa), color-stop(25%, #f2f7fa), color-stop(25%,#ffffff), color-stop(100%,#ffffff)); 
 
\t background: -moz-linear-gradient(left, #f2f7fa 0%, #f2f7fa 25%, #ffffff 25%, #ffffff 100%); 
 
\t background: -webkit-gradient(linear, left top, right top, color-stop(0%,#f2f7fa), color-stop(25%,#f2f7fa), color-stop(25%,#ffffff), color-stop(100%,#ffffff)); 
 
\t background: -o-linear-gradient(left, #f2f7fa 0%,#f2f7fa 25%,#ffffff 25%,#ffffff 100%); 
 
\t background: -ms-linear-gradient(left, #f2f7fa 0%,#f2f7fa 25%,#ffffff 25%,#ffffff 100%); 
 
\t background: linear-gradient(left, #f2f7fa 0%,#f2f7fa 25%,#ffffff 25%,#ffffff 100%); 
 
\t border:1px solid #c1c1c2; 
 
} 
 

 
.col-1, .col-2 { 
 
\t float:left; 
 
\t vertical-align:top; 
 
\t padding:2em 3em; 
 
} 
 

 
.col-1 { 
 
\t position:relative; 
 
\t width:25%; 
 
\t background:#F2F7FC; 
 
\t border-right:1px solid #c1c1c2; 
 
} 
 

 
.col-2 { 
 
\t width:75%; 
 
\t border-left:1px solid #c1c1c2; 
 
\t margin-left: -1px; 
 
} 
 

 
.col-1:after, 
 
.col-1:before { 
 
    top:100%; 
 
    border:solid transparent;content:""; 
 
    height:0; 
 
    width:0; 
 
    position:absolute; 
 
    pointer-events:none; 
 
    display:block; 
 
} 
 
.col-1:after { 
 
    border-color: rgba(255, 255, 255, 0) rgba(255, 255, 255, 0) rgba(255, 255, 255, 0) #f2f7fa; 
 
    border-style: solid; 
 
    border-width: 21px 0 21px 22px; 
 
    left:100%; 
 
    top: 47px; 
 
} 
 
.col-1:before { 
 
    border-color: rgba(0, 0, 0, 0) rgba(0, 0, 0, 0) rgba(0, 0, 0, 0) #c1c1c2; 
 
    border-style: solid; 
 
    border-width: 22px 0 22px 23px; 
 
    left: 100%; 
 
    top: 46px; 
 
}

<div class="faux-columns cf"> 
 
    <div class="col-1"> 
 
     <h4>First column with bordered triangle pseudo element attached to it. The background needs to be the full height of .faux-columns</h4> 
 
    </div> 
 
    <div class="col-2"> 
 
     <h4> Second column which in some cases will be much taller than column</h4>

Answer 4

Nessuna risposta qui mi ha dato conforto, così sono andato a cercare la verità. Ho aggiunto un po 'più css per fare un punto sulla spaziatura tra due scatole.

CSS:

.wrapper { 
    background-color:gray; 
} 

.container { 
    margin: 25px auto; 
    display: inline-flex; 
} 

.leftbox { 
    height: inherit; 
    display: inline-block; 
    border: 1px solid #D7D2CB; 
    background-color: #FFFFFF; 
    border-radius: 5px; 
    max-width: 550px; 
    margin-right: 18px; 
    align-items: stretch; 
    padding: 15px; 
    width: 100%; 
} 

.rightbox { 
    height: 100%; 
    display: inline-block; 
    border: 1px solid #D7D2CB; 
    background-color: #FFFFFF; 
    border-radius: 5px; 
    align-items: stretch; 
    max-width: 300px; 
    width: 100%; 
    padding: 20px 15px; 
} 

HTML:

<div class="wrapper"> 
    <div class="container"> 
    <div class="leftbox"> 
     There is something here, I am not avoiding it. 
    </div> 
    <div class="rightbox"> 
     Probably something else here but much much much much much much much much much much much much much much much much much much much much much much much much much much much much much bigger. 
    </div> 
    </div> 
</div>
