We know that in web page layout, there are some special cases where we cannot directly use external CSS styles to control DIV styles, such as setting a:hover to A, so how can we change it without applying CSS styles? What about mouseover styles?

You can use onMouseOver (mouse moves over the target) and onMouseOut (after the mouse moves away from the target) to achieve the a tag or other html tagsSet hover style.

You can use it directly on tags, regardless of A tag, SPAN tag, DIV tag, etc.

text-decoration:none"

onMouseOver ="this.style.color='#F00';this.style.textDecoration='underline'"

onMouseOut="this.style.color='#00F';this.style.textDecoration=' none'">DIV

The above sets the default style for the ahyperlink code, the style after the mouse moves to the target and the mouse moves away from the target. The feature code is relatively long.

Important Note: In order to see the same default style after the mouse is moved away, you usually need to use style directly on the label to set the default CSS style and keep it the same as the onMouseOut setting CSS style. In order to avoid the difference between the initial state object style and the style after the mouse moves away from the object.

The above code:

style="color:#00F; text-decoration:none"  
与
onMouseOut="this.style.color=&#39;#00F&#39;;this.style.textDecoration=&#39;none&#39;"

Set the default font color #00F and not display underlines.

The examples of hover style setting methods through regular hover and without external hover are as follows
