柔性盒物品的空间不均匀

Question

我试图通过将flex-grow属性设置为1来使flex-box容器中的项目均匀分布，但它没有任何影响。在包裹之前，物品的列根据最宽的尺寸确定。在所有项目中均匀分配空间的正确方法是什么？

# Without touching the `id` column, I create a sequential column `my_id`, assuming that the name of the  table is `times`:

alter table times add my_id int(3) not null after id;
SET @count = 0;
UPDATE times SET my_id = @count:= @count + 1;

# I use a temporary table `times2` that starts with the second row of the `times_from` column; Here, 9999 can be any large enough number:

create temporary table times2 as select my_id, time_from from times limit 1, 9999;

# Now I add a new column `time_end` to the original table. I update it with data from `time_from` column but 'shifted' by one row upwards:

alter table times add time_end int(2) not null;
update times a join times2 b on a.my_id = (b.my_id - 1) set a.time_end = b.time_from;

# Ensure that the value of `time_end` in the last row is not zero:

update times set time_end = time_to order by my_id desc limit 1;

# The required value is taken by using the minimum of columns `time_from` and `time_end`:

select sum(LEAST(time_to,time_end) - time_from) from times;

# Uncomment below to clean up just after getting the results:
    # alter table times drop column my_id;
    # alter table times drop column time_end;  

如何让所有带有flex-item类的容器均匀分布，所以列的宽度都相同？

Answer 1

如果你想拥有相同的宽度，那么你需要定义每个元素flex-grow:1。或者在元素之间只需要空格，那么只有justify-content: space-between;到父div就足够了。你不需要定义flex-grow：1，如果不需要相等的宽度

.flex-item{
  display: flex;
  justify-content: space-between;
}

.flex-item input, .flex-item label, .flex-item span {flex-grow:1}

<div class="flex-box">
      <div class="flex-item" ng-repeat="campaign in mvm.regionCampaigns.results | orderBy:'name' track by campaign.id">
        <input type="checkbox">
        <label>test</label>
        <span>test</span>
      </div>
    </div>

希望这对你有所帮助。
