动态将元素宽度的宽度更改为固定宽度

Question

I have a div width a fixed width:

// CSS

@media only screen
.column.small-centered:last-child, .columns.small-centered:last-child {
  float: none;
}
.lesson_lt_mc_div .small-centered {
  margin-top: 15px;
  margin-bottom: 15px;
  width: 296px;
}
foundation.css:1@media only screen
.column.small-centered, .columns.small-centered {
  margin-left: auto;
  margin-right: auto;
  float: none;
}
.text-left {
  text-align: left !important;
}

// HTML

<div class="small-3 small-centered text-left columns">
    <input type="radio" name="lt_mc_ans" value="1" id="lt_mc_ans_1"><span> 1. </span>
    <label for="lt_mc_ans_1">I</label>
    <br>
    <input type="radio" name="lt_mc_ans" value="2" id="lt_mc_ans_2"><span> 2. </span>
    <label for="lt_mc_ans_2">rsr rs rsrs rsrs r rrrs</label>
    <br>
    <input type="radio" name="lt_mc_ans" value="3" id="lt_mc_ans_3"><span> 3. </span>
    <label for="lt_mc_ans_3">Very</label>
    <br>
    <input type="radio" name="lt_mc_ans" value="4" id="lt_mc_ans_4"><span> 4. </span>
    <label for="lt_mc_ans_4">She</label>
</div>

The reason I'm using fixed width is that I want the div to be centered and for the text to be aligned to the left. The problem is, when the text is too long it wraps, making the options look ugly.

Is there a way to dynamically change the width of the div with jQuery or JavaScript? (I'm also open to CSS solutions, although I doubt there's any).

Answer 1

USE display:table; margin:auto; display:table; margin:auto; on small-centered class and remove width...

Answer 2

Use an outer and inner element.

Align the text of the outer element in the center. And display the inner element as an inline-block, so it will only be as width as its content.

 .outer { text-align: center; background: lightblue; } .inner { background: lightgreen; display: inline-block; text-align: left; } 

 <div class="outer"> <div class="inner"> Some text in it <br />and some more <br/>and more </div> </div> 

Note: instead of using an inner div, you could use your form... (saves you an element).

Edit

With your HTML (note that I've added the form tag)

 .outer { text-align: center; background: lightblue; } .inner { background: lightgreen; display: inline-block; text-align: left; } 

 <div class="outer small-3 small-centered text-left columns"> <form class="inner"> <input type="radio" name="lt_mc_ans" value="1" id="lt_mc_ans_1"><span> 1. </span> <label for="lt_mc_ans_1">I</label> <br> <input type="radio" name="lt_mc_ans" value="2" id="lt_mc_ans_2"><span> 2. </span> <label for="lt_mc_ans_2">rsr rs rsrs rsrs r rrrs</label> <br> <input type="radio" name="lt_mc_ans" value="3" id="lt_mc_ans_3"><span> 3. </span> <label for="lt_mc_ans_3">Very</label> <br> <input type="radio" name="lt_mc_ans" value="4" id="lt_mc_ans_4"><span> 4. </span> <label for="lt_mc_ans_4">She</label> </form> </div> 

Answer 3

If you change your width attribute to be a min-width attribute and then set the width attribute as follows:

width: intrinsic;
width: -moz-max-content;
width: -webkit-max-content;

It should behave as you expect. More information on the 'max-content' option available here .

Answer 4

您是否不仅可以将div设置为min-width，还可以将CSS的宽度设置为允许文本扩展的最小宽度？
