on means there is an auto-complete function
off means no auto-complete function
The novalidate attribute specifies to cancel the validity check of the form when the form is submitted. After setting this attribute for the form, the validation of the entire form is turned off. All forms within the form control are not validated. Use the method novalidate="novalidate"

The list attribute specifies the datalist element bound to the input box, and its value is the id of a certain datalist element.
The multiple attribute specifies that the input box can select multiple values. This attribute is applicable to email (separated by commas) and file (file).
The min, max, step attributes are used to specify limits for input input types containing numbers or dates.

DIV CSS layout
Common properties of layout
Label float attribute
selector {float: attribute value}
float common attribute values
left label floats to the left
right label floats to the right
none label does not float
Float features: 1. The floating element is out of the document flow and no longer occupies a position in the document. 2. After setting the floating element, the element will move to the left or right of the parent element. 3. Floating elements will not be moved from their parent elements by default. 4. When a floating element moves to the left or right, it will not exceed other floating elements in front. 5. If the floating element is above a block element that is not floated, the floating element cannot move upward. 6. The floating element will not exceed the height of the floating element above it, and at most it will be as high as it. 7. Floating elements will not cover text and text will automatically wrap around the element.
clear float
Selector {clear: attribute value;}
left does not allow floating labels on the left
right does not allow floating labels on the right
both clears floats on both sides at the same time
empty label clear float
Use overflow to clear floats
Applying the overflow:hidden style to a label can also clear the effect of floating on the label.
Label positioning attributes
Selector {position: attribute value;}
static automatic positioning
Relative relative positioning, positioning relative to the position of its original document flow
absolute positioning, positioned relative to its previously positioned parent tag
fixed fixed positioning, equivalent to positioning the browser window
The position positioning mode is only used to define how the label is positioned, and cannot determine the specific position of the label.
The top offset defines the distance of the label relative to the upper edge of its parent label.
The bottom offset defines the distance of the label relative to the bottom edge of its parent label.
leftThe left offset defines the distance of the label relative to the left line of its parent label
top right offset defines the distance of the label relative to the right line of its parent label
Other properties
Selector {overflow: attribute value;}
The visible content will not be trimmed and will be rendered outside the label box
hidden overflow content will be trimmed, and the trimmed content will be invisible
aoto generates scroll bars when needed and adapts to the content that needs to be displayed.
The z-index attribute adjusts the upper and lower positions
layout type
single column layout
multimedia embedding
Video file and audio file formats
Video formats supported by HTML5: ogg, mpeg4, webm
Audio formats supported by HTML5: ogg, mp3, wav
Embed video and audio
Video: <video src="video file path" controls="controls"></video> Whether to display the video plug-in. Text can also be inserted between videos. If the video cannot be displayed, the text can be displayed.
Attributes: autoplay automatically plays the video after the current page is loaded The loop video ends and starts playing again The preload video is loaded when the page loads and is ready to play, but this attribute is ignored if the autoplay attribute is used. Poster When the video cannot be played, link a picture and display the picture according to a certain ratio.
Audio: <audio src="audio file path" controls="controls"></audio>
Attributes: autoplay automatically plays audio after the current page is loaded The loop audio ends and starts playing again The preload audio is loaded when the page loads and is ready to play, but this attribute is ignored if the autoplay attribute is used.
Excessive deformation and animation
over
transition-propensityproperty
noneWithout attributes, excessive effects will be obtained
allAll attributes gain excessive effects
property defines the name of the css property that applies the excessive effect. Multiple names are separated by commas.

ease-out transition effect that ends at a slow speed
ease-in-out transition effect that starts at a slow speed and ends at a slow speed

rotated3d (x-y-z, angle (rotation angle)) comprehensive attribute settings
animation
@keyframes rule animation represents the name of the current animation keyframes-selector key frame selector form (0) means start to (100%) means end css-style defines the animation to respond to when executing the current keyframe
The animation-name attribute is used to define the animation name to be applied. The animation name will be referenced by the @Keyframes rule. animation-name:Keyframename|none none means no animation is applied
The animation-duration property is used to define the time required for the entire animation effect to complete. animation-duration: time
The animation-timing-function attribute is used to specify the speed curve of the animation animation-timing-function: value;
linear specifies a transition effect that starts and ends at the same speed
ease (default) starts slowly then speeds up then ends slowly
Ease-in transition effect that starts slowly and then gradually speeds up
ease-out animation ends at low speed
ease-in-out transition effect that starts at a slow speed and ends at a slow speed
cubic-bezier (n,n,n,n) defines the shape of the Bezier curve of acceleration and deceleration by yourself
The animation-delay property is used to define the delay time for executing animation effects. animation-delay: time defines the waiting time
The animation-iteration-count property is used to define the number of times the animation is played animation-iteration-count: number | infinite; defines the number of playback times
The animation-direction property defines the direction of the current animation playback
The animation attribute is used to define a collection of the above six attributes
