Calendar - How to align symbol and text to left

wmx

Hi @all,
I’m running my MM for a while (now @ v2.16.0), but since the update, the formating for calender seems to has changed.
I run 3 (default) calendars, the upper two with whole width of the column, the third in the left column of two.
I did some adjustments in custom.css for format my calendars.
I tried to get the same column with for the symbol col and symbol an title left aligned. But there are some spaces, I do not how to resize them.

It now looks like this

But I would like to get the red areas all same width.

For testing I colored the fields and they show up like this

Why are the title fields of the upper two calendars different?

These are my custom.css entries for calendars

/* Calendar Einträge - Symbol */
.calendar .symbol {
  font-size: 30px;
  text-align: left;
  width: 34px; 
}

/* Calendar Einträge - Text */
.calendar .title {
  font-size: 36px;
  text-align: left;
  line-height: 40px;
}

/* Calendar Einträge - Zeitpunkt */
.calendar .time {
  font-size: 36px;
  line-height: 40px;
  color: #dddddd; /* white! */
}

Some advices?
How do I align symbol and title to the left?
Is there a way to get this without custom.css?
What is the correct way to control the size of the fields and the size of the space between?
