Angular-Material2：垂直对齐文本和 md-icon 以匹配垂直样式？

Question

I know I am probably missing something here. I am trying to align md-icon and some text vertically, right now the word "sample text" displays below the icon.

<div>
  <md-icon>home</md-icon> Sample Text
</div>

Output:

I did try playing around with vertical align on the Sample Text using a span but couldn't get anything working and felt kind of hacky anyway.

Anyone know how to get this effect?

Answer 1

This is a common issue when using <md-icon> . To align the icon and text, you can put your text inside a span and apply style to that:

<div>
  <md-icon>home</md-icon><span class="aligned-with-icon">Sample Text</span>
</div>

In your component.css:

.aligned-with-icon{
    position: absolute;
    margin-top: 5px;
    margin-left: 5px; /* optional */
}

You can also use relative position if you'll be putting multiple icons in the same div. Here is the css for that:

.aligned-with-icon-relative{
    position: relative;
    top: -5px;
    margin-left: 5px; /* optional */
}

Another option is to use flex display on the outer div and align-items to center :

In your html:

<div class="with-icon">
  <md-icon>home</md-icon>Sample Text
</div>

In your css:

.with-icon {
    display: flex;
    align-items: center;
}

Answer 2

I utilize the inline attribute. This will cause the icon to correctly scale with the size of the button.

    <button mat-button>
      <mat-icon inline=true>local_movies</mat-icon>
      Movies
    </button>

    <!-- Link button -->
    <a mat-flat-button color="accent" routerLink="/create"><mat-icon inline=true>add</mat-icon> Create</a>

I add this to my styles.css to:

• solve the vertical alignment problem of the icon inside the button
• material icon fonts are always a little too small compared to button text

button.mat-button .mat-icon,
a.mat-button .mat-icon,
a.mat-raised-button .mat-icon,
a.mat-flat-button .mat-icon,
a.mat-stroked-button .mat-icon {
  vertical-align: top;
  font-size: 1.25em;
}

Answer 3

You can use

div {
    display: flex;
    vertical-align: middle;
}

or

span {
    display: inline-flex;
    vertical-align: middle;
}

Answer 4

This can be achieved using CSS flexbox

<!-- HTML part -->

<div class="outer-div">
 <mat-icon>home</mat-icon>
 <span>Home</span>
</div>

<!-- CSS part -->
.outer-div {
  display: flex;
  flex-direction: column;
  align-items: center;
}
.outer-div > span {
  font-size: 10px;
}

Answer 5

I must say such a simple thing should automatically work out of the box. But you can use position: absolute to center icon vertically as follow:

You can find a demo here

button {
  /* manually making space for mat-icon because
    mat-icon is not position: absolute
  */
  padding-left: 30px; 
}
::ng-deep .mat-icon{
    font-size: 16px !important; /*change this as per your needs*/
    position: absolute;
    top: 50%;
    transform: translate(-22px, -50%);

    /*centering image inside mat-icon box*/
    display: flex !important;
    justify-content: center;
    align-items: center;
  }
